| Echo Sabre|
|A deceptively swift blade imbued with resonant magic.|
- One Echo Sabre grants a total of 200 health, 0.6 health regeneration, 10 attack speed, 110 mana, 0.4 (+75%) mana regeneration, 0.71% spell damage and 15 (25 to strength and intelligence heroes) attack damage.
- This ability works exclusively for melee heroes.
- Upon proccing, grants the user 490 attack speed until the next attack.
- This means it does not provide guaranteed full attack speed and can be countered by strong attack speed slows.
- The attack speed has no set duration. It lasts until the user makes a second attack, no matter how long they wait.
- Since it is a simple attack speed bonus, it is possible to cancel the second attack and "store" the attack speed for later.
- The second attack is not an instant attack. It uses regular attack animation times and attack cooldowns.
- The movement speed slow is applied on the proccing attack and on the attack after the proccing attack.
- This means it is possible to slow two enemies with one proc, by switching attack targets after the proccing attack.
- The slow of multiple instances does not stack, but refreshes the duration instead.
Recommended heroesChaos Knight
- Provides Chaos Knight with good overall stats and some extra mana regeneration.
- Additionally, the slow from Echo Strike synergizes well with Reality Rift and the potential critical strike from Chaos Strike.
- The slow also means that Chaos Knight can possibly chase down a hero without needing to use the mana intensive Chaos Bolt.
- Combined with the extra attacks from Moment of Courage, Echo Sabre can quickly bring down an opponent during a Duel.
- Fast strikes with Feast does burst damage, and also provides Lifestealer with a means of quick health recovery.
- A good item for semi-carry Magnus, as he has large physical damage potential with his talents.
- Typically, this build forgoes the usual Arcane Boots and thus Echo Sabre fills the necessity for some mana regeneration.
- Allows Monkey King to quickly build up Jingu Mastery stacks.
- During his ultimate, clones will apply the slow on every hit.
- Echo Sabre allows Cloak and Dagger's backstab damage to hit twice before targets have time to turn around.
- If Echo Sabre is off cooldown, Tricks of the Trade places Echo Sabre's two slow procs on two randomly selected enemies that were hit. If there is only one hero in the radius, they will be slowed by the first proc. The second proc will then be applied on a randomly selected hero in the radius during the next round of attacks.
- Echo Sabre allows Slark to gank with ease, locking down targets and quickly gaining a double stat conversion through Essence Shift.
- Furthermore, the slow from the double attack facilitates a successful Pounce leash.
- Echo Sabre gives Spirit Breaker a better chance of triggering Greater Bash, and boosts his slow attack speed.
- A well farmed Sven can deal massive damage with a crit item and God's Strength, sometimes killing enemies in one hit. Echo Sabre makes that even more likely. Even without a crit item, a double attack from Sven with God's Strength active deals crippling damage to enemies.
- Tiny can use Echo Sabre to hit twice while an enemy is Tossed, increasing his burst damage. It also solves his mana issues, as well as improving his ability to push with Aghanim's Scepter equipped.
- Echo Sabre gives Wraith King a better chance of landing a crit with Mortal Strike, and boosts his slow attack speed.
- Echo Sabre allows Ursa to burst down enemies by quickly building up his Fury Swipes stacks.
- However, the instant extra attack somewhat wastes Overpower's increased attack speed.
- Melee heroes with passive disables work well with Echo Sabre, giving them a greater chance to lock down enemies by compounding the effects.
- Slardar with his Bash of the Deep.
- Faceless Void with his Time Lock.
- Spirit Breaker with his Greater Bash (still goes on cooldown after a successful proc).
- Lone Druid's Spirit Bear with its Entangling Claws (still goes on cooldown after a successful proc).
- Troll Warlord with his bash from Berserker's Rage.
- Melee heroes with passive crit abilities generally work well with Echo Sabre, giving them a greater chance to proc crits.
- When Kunkka is played together with Keeper of the Light, Echo Sabre can be a very powerful item in the later stages of the game, as it allows Tidebringer combined with Chakra Magic's cooldown reduction to hit twice in succession, dealing massive amounts of cleave damage.
- The best items in combination to increase your damage are those who grant critical hit and armor reduction. A Skull Basher is also good to get a chance to bash from the two quick attacks.
- Echo Sabre's ability is effectively a passive 1-hit-only Overpower. This makes it a great item on heroes whose passive abilities rely on attack speed to be effective, similar to how Ursa's Fury Swipes relies on the attack speed of Overpower.
- The attack speed from the passive proc lasts until a second attack is done. This makes it possible to "store" the massive attack speed bonus for a planned strike on an enemy. One just has to attack a creep to proc the passive ability and immediately cancel the second attack. The stored attack speed can come very handy when ganking enemies which have strong attack speed slows like Enchantress with her Untouchable or Phoenix' Fire Spirits.
- Prior to the July 14, 2017 Patch, Echo Sabre's passive ability, Echo Strike, did not have an official name. The name was taken from the Dota 2 Wiki and officially implemented into Dota 2.
