Gameplay[edit]

Playstyle
Oracle minimap icon.png Oracle is a versatile spell caster whose spells can be used defensively or offensively depending on how the combinations of spells are used. A well timed ultimate can change a surprise attack from the enemy into a failed gank. Oracle is not very mobile and is susceptible to getting picked or focused first in fights if poorly positioned.
Pros Cons
  • Strong spammable nukes.
  • Great spell utility, Fate's Edict can be used to negate magical damage or disarm opponents for example.
  • Can save his allies with ease (or his enemies).
  • Can make combos with all of his available, for healing or damaging, disarming or magic immunity.
  • Can purge debuffs.
  • Easy last hits with his Purifying Flames.
  • Lacks any strong area of effect spells.
  • Inexperienced players might cause more harm than good to their team or aid the enemy if they cast the wrong spells at the wrong time.
  • Players need to be experienced with this hero before using his spells, as Oracle is one of the hardest heroes to play.
  • Very dependent on his allies.
  • Quite easy to kill because of his low Strength gain, unless he uses one of his spells as an escape.

Support[edit]

Oracle is almost always played as a support. If there are vital spells to purge (e.g. Hex (Lion) icon.png Hex) or getting a strong Fortune's End and Purifying Flames combination is important, more points should be invested in Fortune's End. If the enemy has strong physical attack carries or relies heavily on spell damage, more points should be invested into Fate's Edict. Having more points in Fate's Edict allows Oracle to get the spell off a lot easier with the increased range as well and a longer duration.

Tips & Tactics[edit]

General[edit]

  • Oracle's strength lies not in his individual spells, but in how he utilizes his spells in combination with each other, as well as those of his teammates. This means that playing Oracle effectively requires communication and coordination with allied players, as well as good reflexes and knowledge of what each ability does.
  • Like most other intelligence supports, Oracle suffers from poor strength and agility, making him extremely vulnerable to any types of damage. Because of his array of abilities, Oracle should build items that provide mobility rather than survivability, since he can use mobility items both to position himself for casting his spells and to escape enemy attempts to kill him. As well, his heavy reliance on spell casting means that he should invest in increasing the size of his mana pool and acquiring a reliable source of mana replenishment.
  • Be mindful that while Oracle has strong healing and nuking abilities, he possesses no hard disables, meaning that he is unable to interrupt channeling items/abilities, nor is he able to prevent enemies from casting spells or using items. In order to counter enemy spell and item usage, Oracle must himself purchase items to allow him to hard-disable the enemy, or rely on his allies to do so.
  • Oracle's spells all have very high cast ranges, and his good base movement speed allows him to get into position to use his spells relatively easily. However, his extremely low turn rate means that he cannot maneuver as easily as other heroes, so his ability to turn around to cast spells in surprise situations may allow the enemy to catch him off-guard. This means that prior knowledge of the enemy's positions and movements can allow him to orient himself to face the threat axis and be ready to use his spells immediately, making ward vision very important.
  • With his long attack range, respectable cast animation, and extremely low base attack time, Oracle is a very powerful harasser in the laning stage, able to inflict harass damage on enemy heroes safely and frequently, as well as deny effectively with his respectable base damage. Combined with his array of impact-heavy abilities and high base movement speed, this allows Oracle to be a very strong lane support who can very easily protect his safe lane carry.

Abilities[edit]

Fortune's End icon.png Fortune's End[edit]

  • Fortune's End is a channeled nuke that damages enemies in an area around the target, while purging them and immobilizing them based on the channel duration.
  • Because its damage and cooldown scale as it is leveled up, Fortune's End is a good spell to max out early in the game. Leveling up the ability increases Oracle's ability to nuke and disable enemies, and the dispel has strong utility depending on the types of buffs that the enemy is depending on.
  • Fortune's End is a very flexible nuke that can be used in a number of ways. Chief among its utility is to deal nuke damage to an enemy while removing buffs, or to stop an enemy for the channeled duration as a follow-up disable from an allied initiation.
  • Be mindful that no matter how long Fortune's End is channeled, it will deal the same amount of damage regardless. Channeling Fortune's End for a longer duration only increases the amount of time that affected enemies are immobilized, so if the aim of casting the spell is to simply deal damage and/or purge rather than disable, the spell can be immediately released in order to give the enemy less time to react.
  • Never discount the area purging and immobilizing that Fortune's End can provide. If the spell can land on a clumped up group of enemies, the amount of damage it deals increases severalfold, along with purging many more buffs from the enemy and pinning them down for follow-up area disables by teammates.
  • Be careful about using Fortune's End as an initiating disable. Because the enemy can see the spell effects even if Oracle himself is not visible, they will immediately know that they are being targeted by the spell, and can immediately retreat to avoid being caught in a disadvantageous position, or easily disjoint the projectile.
  • Unlike most other purging-type spells, Fortune's End can still target invulnerable units (it is still blocked by spell immunity, however). This makes it a very powerful ability since it can forcibly remove certain instances of invulnerability, particularly a self-cast Eul's Scepter of Divinity.
  • As a root, Fortune's End prevents affected heroes from using certain abilities to move, like Ball Lightning icon.png Ball Lightning and Tree Dance icon.png Tree Dance. However, root does not stop channeling abilities and items.

Fate's Edict icon.png Fate's Edict[edit]

  • Fate's Edict inflicts its target with a disarm while increasing their magic resistance to 100%. It can be cast on allies and enemies alike.
  • Because its duration only scales by 0,5 second for each level, Fate's Edict is best left at level 1 until both Fortune's End and Purifying Flames are maxed out. However, its strong utility means that an early value point can be very strong as it greatly synergizes with Oracle's other spells.
  • Keep in mind that due to Oracle's cast times level 2 of Fate's Edict is needed to cast 2 successive Purifying Flames onto a friendly target and block the damage of both.
  • Generally, Fate's Edict has two primary purposes: protecting allies from magic nukes, or disarming enemies to prevent them from attacking.
    • Casting Fate's Edict on fleeing allies can save them from incoming magic nukes, particularly long-ranged single-shot ones like Assassinate icon.png Assassinate and Thundergod's Wrath icon.png Thundergod's Wrath, and can be used to mitigate the effects damage-over-time debuffs such as Ice Blast icon.png Ice Blast and Poison Nova icon.png Poison Nova. Properly used, Fate's Edict can allow Oracle to defy his allies' fates by preventing their deaths due to magical damage.
    • Casting Fate's Edict on enemies during a fight can render them unable to attack, important for stopping their right-click carries from attacking. If the enemy does not have any dispel abilities or items, a good Fate's Edict can render their carry unable to attack for a period of time, greatly increasing the odds of winning a teamfight.
  • Be very careful about when you cast Fate's Edict on an ally or enemy. Using the ability on an ally in the middle of a fight can prevent them from attacking, hindering their ability to kill enemies, while using it on an enemy can shield them from incoming allied magic nukes. Use your best judgment as to when Fate's Edict can be most profitably used, as casting it on the wrong target at the wrong time can reduce your team's chances at emerging victorious in an engagement.
  • It is possible to manually remove Fate's Edict from an enemy via the use of Fortune's End. If an enemy affected by Fate's Edict is fleeing and needs to be finished off with magic nukes, casting Fortune's End on them will remove it from them, while dealing nuke damage and immobilizing them to allow allies to follow up.
  • Fate's Edict can also be used as a simple magic resistance buff on allies that do not rely on auto-attacks to be effective. For instance, casting Fate's Edict can allow a teammate to walk into an active Freezing Field icon.png Freezing Field to cast an interrupting disable, or ignore most of Leshrac minimap icon.png Leshrac's damage output while directly engaging him with spells.
  • The magic resistance of Fate's Edict can synergize greatly with many other effects in the game.
    • An ally affected by Cold Embrace icon.png Cold Embrace is immune to physical damage but can still be burst down by Magical and Pure. Casting Fate's Edict on the target can shield them from magic nukes for the duration of the disable, and the disarm can be neglected due to the target being unable to act anyways.
    • Any form of ethereal will leave its target unable to attack or be affected by physical damage, but decreases their magic resistance at the same time. Casting Fate's Edict in such a situation would render them invulnerable to magical damage as well, and the target will have already been disarmed by the ethereal form.
  • Use Fate's Edict on Roshan to disarm him, negating most of his damage and bashes.

Purifying Flames icon.png Purifying Flames[edit]

  • Purifying Flames is an extremely low cooldown magic nuke that applies a healing buff to its target. It can be cast on allies and enemies.
  • As a multipurpose heal and nuke, Purifying Flames is a very powerful spell to max out first. Its damage scales much higher than Fortune's End, and the heal can be very powerful at all points in the game.
  • Oracle's greatest strength is his ability to combine Purifying Flames with his other abilities, using them to completely change how it benefits his team and debilitates the enemy.
    • The 100% magic resistance element of Fate's Edict can be used to great effect when combined with Purifying Flames. Casting Fate's Edict on an ally first, followed by Purifying Flames, will cause allies to take no damage from the nuke portion, and benefit only from the healing portion. As Purifying Flames can be stacked, higher levels of Fate's Edict allows Oracle to heal allies for larger amounts of health per cast.
    • Fortune's End can purge positive buffs from enemies, Purifying Flames included. Casting Purifying Flames on an enemy first, then hitting them with Fortune's End, will cause them to be healed for the minimal amount of HP while taking the full brunt of the nuke damage from both spells.
  • Be wary that the damage portion of Purifying Flames will always take magic resistance into account, whether it is cast on an ally or enemy. This means that unless the target is inflicted with powerful magic resistance debuffs, they will always be healed for more HP than the damage taken. This means that abilities such as Spell Shield icon.png Spell Shield and Berserker's Blood icon.png Berserker's Blood can greatly mitigate the nuke portion of Purifying Flames, which can be a boon or a hindrance depending on which team possesses either hero.
    • Assuming basic 25% magic resistance and factoring in the initial damage, it can effectively heal up to 31.5/63/94.5/126 health per cast (not considering any further damage manipulating factors, such as spell amplification).
  • The short cooldown and small mana cost on Purifying Flames allows it to be used as a basic nuke. This can be used either to finish off low-health enemies, or score easy last-hits. Beware, however, that unless the target is killed quickly, they can eventually heal up a large amount of HP, which may necessitate the use of Fortune's End.
  • When using Purifying Flames in combination with Fortune's End to nuke enemies, keep in mind that Fortune's End has a travel time, while Purifying Flames will instantly apply its effects at the end of its cast animation. Start the attack, wait for the projectile to appear, and with the right timing of Purifying Flames the nuke will hit just before the projectile lands. Or, if an enemy is within range of Purifying Flames but is more than 400 range away, Fortune's End can be channeled first and then interrupted with Purifying Flames; the enemy will take the damage from Purifying Flames during the travel time of Fortune's End, and then immediately have the healing buff removed and be nuked by Fortune's End.
  • Purifying Flames, by itself, will never be lethal to allies. This allows Oracle to save time by directly casting Purifying Flames on a low-health ally rather than consuming time and mana with Fate's Edict first. However, be sure to check for damage over time debuffs first, and never do this if an enemy is nearby, as it can put teammates low enough for the enemy to easily finish off.
  • As with Fate's Edict, Purifying Flames can be used to great effect depending on what heroes are present on Oracle's team.
    • In the case of an ally being shielded by Cold Embrace icon.png Cold Embrace and Fate's Edict, Purifying Flames can be added on top to further magnify the healing effect of Cold Embrace, significantly boosting the amount of HP healed inside of a few seconds.
    • If the enemy has been affected by Ice Blast icon.png Ice Blast, repeatedly nuking them with Purifying Flames can prevent them from benefiting from the heal for the duration of the debuff, especially if the allied Ancient Apparition has an Aghanim's Scepter.
  • Beware that Purifying Flames is still registered as player damage, even when targeted on an ally, and can trigger on-damage effects. This means that it can remove layers of Refraction icon.png Refraction, Living Armor icon.png Living Armor and Gravekeeper's Cloak icon.png Gravekeeper's Cloak if not shielded by Fate's Edict first, and can cancel Clarity icon.png Clarity, Healing Salve icon.png Healing Salve and Urn of Shadows icon.png Urn of Shadows even if Fate's Edict was cast first; it can even put an allied Blink Dagger icon.png Blink Dagger on cooldown at an inopportune moment if not shielded by Fate's Edict first. Be careful about when you use Purifying Flames to heal allies, as using it even in situations with no present threats can be a detriment to your team.
  • Purifying Flames is a strong lane control spell as it can be used to secure last hits and denies as the spell has a relatively low mana cost and it does not have a projectile.
    • A neat trick about Purifying Flames is that it can act as a pseudo Sacrifice icon.png Sacrifice from level 2 and above. Simply cast it on your range creep and start denying it before it heals past the 50% threshold.

False Promise icon.png False Promise[edit]

  • False Promise temporarily delays all damage and healing done to an ally, while applying a strong dispel on them, dealing its damage and double the heal at the end of the duration.
  • The delayed damage at the end of the spell can be lethal, meaning that the target for False Promise is not guaranteed to live. However, all healing done during the spell is doubled, which means that enough healing items and abilities can allow Oracle to save an ally from the brink of death and restore them to full health at the end of the spell.
  • Constant use of Purifying Flames during False Promise, along with any other healing abilities and items, are key to allowing a teammate to survive at the end of the spell, as the doubled healing portion will allow the target to recover far more health than the damage they take from the nuke portion. Depending on the situation, casting Fate's Edict first may or may not be a good idea, as the disarm can prevent the target from attacking during the spell despite the strong dispel.
  • Because the heal is doubled at the end of the spell, False Promise greatly benefits from healing sources that are not Oracle himself. Abilities like Chemical Rage icon.png Chemical Rage, Inner Vitality icon.png Inner Vitality, Death Pulse icon.png Death Pulse and so on can go a long way towards ensuring the survival of the target at the end of the spell.
  • Beware that it is still possible for a False Promise target to be disabled during the spell, as area disables like Chronosphere icon.png Chronosphere, Black Hole icon.png Black Hole, Static Storm icon.png Static Storm, or Smoke Screen icon.png Smoke Screen do not place a dispellable debuff on the affected units. As well, spells like Doom ability icon.png Doom and Demonic Purge icon.png Demonic Purge place debuffs that cannot be dispelled. Take the enemy's spell composition into account when using False Promise, as casting it on the wrong target or at the wrong time can still waste the spell.
  • The damage vs healing calculation does not take into account whether the damage is non-lethal or lethal. While the damage from Purifying Flames is normally non-lethal, it nevertheless still contributes fully to the damage calculations.
    • Example 1: Unit A is on 100 HP. Oracle casts False Promise on Unit A. Unit B deals 700 damage to Unit A. Oracle casts Purifying Flames twice to Unit A, dealing 600 damage but healing 1000 during the remaining of the False Promise duration. Total damage = 1300. Total healing = 1000. Therefore, once False Promise ends, Unit B lands the killing blow of 100 damage onto Unit A.
    • Example 2: Unit A is on 700 hp. Oracle casts False Promise on Unit A. Unit B deals 600 damage to Unit A. Near the end of the False Promise duration, Oracle casts Purifying Flames on Unit A, dealing 300 damage and only healing for 100. Total damage = 900. Healing = 50. Therefore, once False Promise ends, Unit B deals 600 damage to Unit A, and Oracle deals 99 (non-lethal) damage to Unit A, leaving Unit A at 1 hp.
    • Casting Purifying Flames with less than 5 seconds of False Promise remaining is thus not a good idea.

Items[edit]

Starting items:

  • Tango icon.png Tango sustains Oracle's health in-lane, preventing him from being harassed away by enemy attacks.
  • Iron Branch icon.png Iron Branch is cheap and gives Oracle extra attributes. It can be used to build Magic Wand or Mekansm.
  • Clarity icon.png Clarity restores mana so Oracle can use his abilities on enemies and allies more often.
  • Animal Courier (Radiant) icon.png Animal Courier ferries items to allies.

Early game:

  • Magic Stick icon.png Magic Stick allows Oracle to instantly replenish his health and mana, useful in a tight situation or in the middle of a teamfight, surviving just long enough to cast one or two more of his high-impact spells to change the tide of an engagement.
  • Boots of Speed icon.png Boots of Speed helps boost Oracle's respectable base movement speed. In the early game, it allows him to quickly get within range to cast Fortune's End on an enemy during a gank.
  • Wind Lace icon.png Wind Lace also provides a small movement speed bonus, a great cost-effective item for supports; it can upgrade to Eul's Scepter of Divinity later.

Mid game:

  • Magic Wand icon.png Magic Wand gives Oracle extra attributes, crucial to have on a hard support with no farm priority. The extra charge storage can give Oracle enough mana to cast his ultimate, or another round of his basic spells.
  • Arcane Boots icon.png Arcane Boots increases Oracle's mana pool, allowing him to get more out of his spells, and the active can replenish mana for himself and his allies.
  • Mekansm icon.png Mekansm replenishes the health of teammates and Oracle. Most notably, use in tandem with False Promise to heal an ally for 500 HP rather than 250.
  • Observer Ward icon.png Observer Ward provides crucial vision for Oracle's team. Knowing where the enemy is allows him to be present at fights to change the fate of allies and enemies alike.
  • Town Portal Scroll icon.png Town Portal Scroll gets Oracle to be in the right place at the right time because his ability to defy fate with his spells makes him a powerful ally to have in any fight.

Late game:

  • Glimmer Cape icon.png Glimmer Cape is a powerful utility item that synergizes with Oracle's ability to protect teammates. Cast on an ally, it can help with initiation for casting short-ranged disables in lieu of a Blink Dagger. As well, it can be cast in place of Fate's Edict to give an ally invisibility as well as increased magic resistance when fleeing. While not as strong as Fate's Edict at mitigating damage from Purifying Flames, it does not disarm the target, allowing them to act if needed.
  • Aether Lens icon.png Aether Lens provides as extra mana and mana regeneration and can be built with Energy Booster disassembled from Arcane Boots. The increased cast range allows Oracle to use abilities and items from a safe distance.
  • Guardian Greaves icon.png Guardian Greaves greatly improves Oracle's support potential, allowing him to replenish both health and mana for his allies. Just as importantly, using the active allows Oracle to remove debuffs from himself, chief among them silences that may be preventing him from casting spells.
  • Force Staff icon.png Force Staff is an easy-to-build item that gives Oracle many good benefits and synergizes with his abilities. The increased intelligence gives him more mana, while the health regeneration keeps his health topped up. The active allows Oracle to quickly re-position himself for casting his spells, and in a pinch can be used as an escape ability. It can be cast during False Promise to help a fleeing ally clear the area faster and put them in a safer place from where Oracle can quickly heal them back up.
  • Eul's Scepter of Divinity icon.png Eul's Scepter of Divinity greatly improves Oracle's casting ability while giving him a powerful active. The increased intelligence and mana regeneration fuel Oracle's spell casting, ensuring that he can use his spell combos more easily, and the bonus movement speed grant him more mobility for positioning himself for casting his spells. The active can be cast on himself to purge debuffs (such as silences) while providing temporary invulnerability, or can be targeted on an enemy as a hard-disable that purges buffs, doubling up on his ability to do so with Fortune's End.

Situational items:

  • Blink Dagger icon.png Blink Dagger gives Oracle greatly improved mobility and positioning. Getting within range to cast his spells allows Oracle to change the tide of engagements, and it can also help to increase his mobility around the map, reaching hot-spots more easily and allowing him to escape ganks as needed, especially as False Promise can be used to prevent it from going on cooldown due to player damage.
  • Flying Courier (Radiant) icon.png Flying Courier is crucial to purchase as early as possible, in order to facilitate ferrying important items to Oracle's team.
  • Sentry Ward icon.png Sentry Wards should be regularly purchased along with Observer Wards, in order to de-ward enemy vision where possible.
  • Urn of Shadows icon.png Urn of Shadows is a useful support item and synergizes well with False Promise, doubling Urn's heal amount.
  • Medallion of Courage icon.png Medallion of Courage is a useful utility support item that gives Oracle many benefits. It increases Oracle's armor, giving him more survivability, and some mana regeneration for sustaining his mana pool. While Oracle does not specialize in dealing physical damage, the active can be cast on allies to give them more survivability, particularly during False Promise to increase the odds of surviving. Upgrading to a Solar Crest icon.png Solar Crest further increases the benefits it provides.
  • Pipe of Insight icon.png Pipe of Insight is a strong teamfight item that helps Oracle to further protect his teammates. The magic resistance and health regeneration help to make Oracle more survivable, while the aura gives his team improved resistance to magic damage, including from Purifying Flames. Using the active in a teamfight will allow him to shield allies from enemy magic damage, without having to resort to Fate's Edict.
  • Lotus Orb icon.png Lotus Orb is an expensive but powerful utility item that allows Oracle to take False Promise to its limit. The item gives Oracle more armor, increasing his survivability, and health and mana regeneration for self-sustain. Echo Shell, when cast on a False Promise target, can dissuade enemies from targeting them with single-target abilities, increasing the target's survivability.
  • Aghanim's Scepter icon.png Aghanim's Scepter reduces cooldown of Purifying Flames, making it a highly defensive purchase in the late game because Oracle can use the ability more frequently for massive amount of heal during False Promise.
  • Shiva's Guard icon.png Shiva's Guard greatly improves Oracle's survivability and gives him more casting power. The intelligence greatly increases the size of his mana pool, while the armor helps him to resist physical damage. The Freezing Aura can reduce enemy attack speed, allowing Oracle to reduce the effectiveness of enemy physical attacks, particularly against a False Promise target, while Arctic Blast can be used to add more nuke damage and slow enemies from fleeing or pursuing.
  • Scythe of Vyse icon.png Scythe of Vyse is a powerful item to build on any intelligence support hero. It improves Oracle's attributes, and greatly increases the size of his mana pool and gives him powerful mana regeneration. The active allows him to instantly hard-disable an enemy from long range, drastically improving his impact in teamfights.
