Gameplay[edit]

Playstyle
Oracle Oracle is a versatile spell caster who can use abilities defensively or offensively depending on different combinations of abilities. A well timed False Promise may change a surprise attack from the enemy into a failed gank. However, Oracle is not really mobile, thereby susceptible to getting picked or focused first in fights if poorly positioned.
Pros Cons
  • Strong spammable nukes.
  • Great utilities, including root, dispel, and disarm.
  • Save allies with ease.
  • Spell combos for healing or damaging.
  • Easy last hits with Purifying Flames.
  • Lacks any strong area abilities.
  • Abilities may have drawbacks depending on the situations.
  • Hard hero to play, requires understanding and experience.
  • Highly dependent on allies.
  • Low strength gain and armor.

Support[edit]

Oracle is almost always played as a support. Maxing Purifying Flames first to heal and nuke. Then, invest in Fortune's End to dispel dangerous disables, or if you want to nuke in combination with Purifying Flames. If the enemy has strong physical attack carries or relies heavily on magical damage, invest in Fate's Edict instead for increased duration and cast range.

Tips & Tactics[edit]

General[edit]

  • Oracle's strength lies not in his individual abilities, but in how he utilizes them in combination with each other, as well as those of his teammates. So, playing Oracle requires communication and coordination with allied players, as well as good reflexes and knowledge of what each ability does.
  • Oracle suffers from poor strength and agility, making him 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 spells and to escape enemy attempts to kill him. Furthermore, 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.
  • While Oracle has strong healing and nuking abilities, he possesses no hard disables, so he cannot interrupt channeling items/abilities, or prevent enemies from using abilities and items.
  • Oracle's abilities have long cast ranges, and his good base movement speed allows him to get into position rather easily. However, his low turn rate may delay abilities usage, so good map vision allows Oracle to face allies and enemies ahead of time to maximize his effectiveness.
  • With his long attack range, respectable cast animation, and low base attack time, Oracle can harass enemies in the laning stage safely and frequently, as well as denying with ease because of decent base damage. Combined with his array of impact-heavy abilities and high base movement speed, Oracle functions as a strong lane support who helps the lane partner immensely.

Abilities[edit]

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

  • Fortune's End damages enemies in an area around the target.
  • Because its damage and cooldown scale with levels, you may find Fortune's End a good ability to max out early in the game.
  • Fortune's End's dispel removes buffs from the enemies in an area.
  • Fortune's End's root stops enemies in an area for the channeled duration, serving as extra disable to follow after or set up allied abilities.
  • Channeling Fortune's End longer only increases rooting time.
  • Stop channeling Fortune's End immediately after casting if Oracle only wants to damage and apply dispel.
  • Never discount the area dispel and root that Fortune's End can provide. If the ability can land on a clumped up group of enemies, it actually deals great amount of damage, along with dispelling buffs and pinning the enemies down for follow-up area disables from teammates.
  • Avoid using Fortune's End as an initiating disable. Enemies can see the marking of Fortune's End's visual effects on themselves as Oracle is channeling, so they most likely will retreat to safety or have enough time to disjoint the projectile.
  • Unlike most other dispel, Fortune's End can target invulnerable units. So, it can 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.
  • Start channeling Fortune's End on mobile allies, then release the projectile as they approach the enemies to apply the long duration root.

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

  • Fate's Edict disarms targeted enemies or allies, while increasing their magic resistance to 100%.
  • Have an early value point in Fate's Edict because it synergizes well with Oracle's other abilities.
  • Oracle does not need to invest further in Fate's Edict because it only increases duration by 0.5 second for each level, making it less attractive than the damage and utilities of Forune's End and Purifying Flames.
    • However, maxing Fate's Edict early reduces its cooldown and increases its duration, allowing Oracle to keep disarming strong enemy carries right from early fights.
  • Oracle may want level 2 Fate's Edict to use two successive Purifying Flames onto a friendly target and block the damage of both.
  • Use Fate's Edict on fleeing Oracle and allies to save them from incoming magical nukes, particularly long-ranged single-shot ones like Assassinate icon.png Assassinate and Thundergod's Wrath icon.png Thundergod's Wrath.
  • Use Fate's Edict to mitigate magical damage-over-time debuffs such as Ice Blast icon.png Ice Blast and Poison Nova icon.png Poison Nova.
  • Use Fate's Edict on enemies during a fight to disarm them, particularly attacking carries, gimping the enemy overall damage output in fights.
  • Misuses of Fate's Edict on either allies or enemies lead to disastrous outcomes, stopping friendly carries from attacking or shielding enemies from allied magical nukes.
  • Oracle may remove the debuffs of Fate's Edict from an enemy by using Fortune's End on them, making them susceptible to magical damage again so Oracle and allies can clean up.
  • Fate's Edict works as a simple magic resistance buff on allies who do not rely much on attacks.
    • For instance, Fate's Edict protect allies from magical damage when they are channeling abilities like Freezing Field icon.png Freezing Field, or just running rampage with Pulse Nova icon.png Pulse Nova.
  • The magic resistance of Fate's Edict synergizes with many other effects in the game.
    • Cold Embrace icon.png Cold Embrace protects target from physical damage while Fate's Edict adds magic resistance on top. Furthermore, Cold Embrace already disables the target, making disarm irrelevant.
    • Any form of ethereal will leave its target unable to attack or take physical damage, but decreases their magic resistance at the same time. Using Fate's Edict in such a situation would render them invulnerable to magical damage as well, and ethereal form already disarms the target.
  • Use Fate's Edict on Roshan to disarm him, negating most of his damage output and bashes.
  • To kite a melee hero, use Fate's Edict on your target, wait 0.5/1/1.5/2 seconds and channel Fortune's End for max duration. With maxed Fate's Edict, Oracle can use it a second time. With maxed Fate's Edict and Fortune's End, Oracle can repeat the combo forever.
    • This means you can ignore Purifying Flames and max out Fate's Edict and Fortune's End first against melee carries like Ursa Ursa.
    • You may also consider skipping False Promise at level 6 it works better with the heal from Purifying Flames, but Oracle can just buy Urn of Shadows icon.png Urn of Shadows.

Purifying Flames icon.png Purifying Flames[edit]

  • Targeting friends and foes alike, Purifying Flames deals magical damage on low cooldown, and also applies a heal.
  • Max out Purifying Flames first for great damage and heal. Its damage scales much higher than Fortune's End, and the heal works well at all points in the game.
  • Use Fate's Edict first on friendly target to give them 100% magic resistance, then use Purifying Flames to apply the heal without dealing any magical damage to them. As Purifying Flames can stack with each other, higher levels of Fate's Edict extends the magic resistance's duration, giving Oracle better time window to heal allies more.
  • Use Purifying Flames on an enemy first to nuke them, then use Fortune's End to dispel the heal and deal more damage.
  • At base magic resistance for heroes, Purifying Flames always heals more than it damages at the end.
  • Take high magic resistance into account when using Purifying Flames, as abilities like Spell Shield icon.png Spell Shield and Berserker's Blood icon.png Berserker's Blood make the heroes take less damage, thus enjoying more heal, which could help or hinder Oracle.
  • Use Purifying Flames as a magical nuke to either finish off low-HP enemies, or score easy last hits.
    • Make sure to finish off the target quickly after Purifying Flames, since they will eventually heal up a good amount, which may necessitate the use of Fortune's End.
  • Use Purifying Flames with Fortune's End to nuke enemies. Ideally, you want Fortune's End's projectile to land right after Purifying Flames hit so enemies will not benefit from the heal.
    • If an enemy is within the cast range of Purifying Flames but is more than 400 distance units away from Oracle, channel Fortune's End and then interrupt it at anytime with Purifying Flames. The enemy will take the damage from Purifying Flames during the travel time of Fortune's End's projectile, and then it will immediately remove the healing buff and deal damage.
  • Purifying Flames, by itself, cannot kill Oracle or allies, allowing Oracle to just use Purifying Flames on a low-HP ally without wasting time and mana with Fate's Edict first.
    • However, always check for damage over time debuffs and nearby enemies first because they may just finish off the low-HP ally before Purifying Flames can heal.
  • Pair with Ice Blast icon.png Ice Blast or Spirit Vessel icon.png Spirit Vessel to prevent enemies from healing up from Purifying Flames.
  • Purifying Flames registers as player damage, even when targeted on an ally, and can trigger on-damage effects. That is, it removes layers of Refraction icon.png Refraction, Living Armor icon.png Living Armor, and Gravekeeper's Cloak icon.png Gravekeeper's Cloak. It cancels Clarity icon.png Clarity, Healing Salve icon.png Healing Salve, and Urn of Shadows icon.png Urn of Shadows. It even puts an allied Blink Dagger icon.png Blink Dagger on cooldown.
    • Thus, start with Fate's Edict so the allies do not take damage from Purifying Flames.
  • Use Purifying Flames to secure last hits and denies as it has a relatively low mana cost and does not have a projectile.
  • Like using Sacrifice icon.png Sacrifice in lane, level 2 or higher Purifying Flames allows Oracle to deny ranged creeps. Simply use it on ranged creeps and keep attacking to deny.

False Promise icon.png False Promise[edit]

  • False Promise temporarily delays all damage and healing done to an allied target, while applying a strong dispel on them at the beginning, dealing its damage and double the heal at the end of the duration.
  • The delayed damage at the end of False Promise will result in death if the target takes too much damage but not enough healing from Oracle and teammates.
  • The orb above targeted hero will grow bright red, warning that they are taking excessive damage and will probably die at the end of False Promise.
  • Usually, the double healing during False Promise should save the target if Oracle and teammates keep using healing items and abilities on the target.
  • Keep using Purifying Flames during False Promise because it doubles the healing done during its duration, most likely surpassing that of the damage.
  • Avoid using Fate's Edict during False Promise when fighting as the target usually wants to attack and deal as much damage as possible.
  • Since False Promise halts all incoming damage during its duration, items like Healing Salve icon.png Healing Salve, Bottle (Full) icon.png Bottle, Urn of Shadows icon.png Urn of Shadows, and Spirit Vessel icon.png Spirit Vessel will continue to heal the targeted hero even if the enemies are attacking.
  • Because False Promise doubles any heal during its duration, rely on abilities like Chemical Rage icon.png Chemical Rage, Inner Vitality icon.png Inner Vitality, or Death Pulse icon.png Death Pulse to keep target alive.
  • Watch for certain abilities like Doom ability icon.png Doom or Hex (Shadow Shaman) icon.png Hex which place debuffs that even False Promise cannot dispel.
  • The damage versus 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 uses False Promise on Unit A. Unit B deals 700 damage to Unit A. Oracle uses 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 uses False Promise on Unit A. Unit B deals 600 damage to Unit A. Near the end of the False Promise duration, Oracle uses 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.
    • Therefore, using Purifying Flames with less than 5 seconds of False Promise remaining is not a good idea.
  • Using False Promise before Aeon Disk icon.png Aeon Disk activates to guarantee that whatever damage False Promise delays will be nullified by Aeon Disk, and target will always survive. Though Disk only triggers to hero-based damage, therefore if you get damaged during False Promise at least once by non-hero source Aeon Disk will not save you.

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.
  • Observer Ward icon.png Observer Ward provides crucial vision for Oracle's team. Knowing the enemy positions allows him to be present at fights to change the fate of allies and enemies alike.
  • Healing Salve icon.png Healing Salve helps Oracle heal after early fights and cycles well in the mid game with False Promise to guarantee and double the healing from it.

Early game:

  • Infused Raindrop icon.png Infused Raindrop adds some survivability early on and fixes Oracle's mana issues in tough lanes.
  • 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.
  • Urn of Shadows icon.png Urn of Shadows grants charges when Oracle contributes in kills; furthermore, enemies cannot cancel the heal when Oracle uses it with False Promise.

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.
  • 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.
  • Aether Lens icon.png Aether Lens provides 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 an even safer distance, combining with his high movement speed and already long range abilities makes Oracle's range of action extremely wide.
  • Spirit Vessel icon.png Spirit Vessel, upgraded from Urn of Shadows, provides good movement speed, health, and a fine buff to the active which brings trememdous sustainability to Oracle and allies especially under False Promise.

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.
  • 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 dispel debuffs (such as silences) while providing temporary invulnerability, or can be targeted on an enemy as a hard-disable that dispels buffs, doubling up on his ability to do so with Fortune's End.

Situational items:

  • Tranquil Boots (Active) icon.png Tranquil Boots give mobility and keep Oracle at max health, saving the mana to heal allies instead of himself.
  • 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.
  • Sentry Ward icon.png Sentry Wards should be regularly purchased along with Observer Wards, in order to de-ward enemy vision where possible.
  • Medallion of Courage icon.png Medallion of Courage gives Oracle armor for survivability, and some mana regeneration for sustaining his mana pool. Oracle can use the active 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 with added evasion. Additionally, Oracle can use these items on enemies to reduce their armor so his allies can deal more physical damage.
  • 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.
  • Aeon Disk icon.png Aeon Disk saves Oracle from burst damage and disables at the beginning of fights, keeping him alive to contribute to team efforts.
  • 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.
  • 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.
