Modifiers [?]

  • Triggers upon taking damage greater than 0 (before reductions) from enemy and allied players.
    • Neither triggers on self-inflicted damage nor from damage flagged as HP Removal.
  • Combo Breaker first applies a strong dispel, then two types of Incoming Damage Manipulation Outgoing Damage Manipulation damage reductions on self upon activation.
    • Effectively negates the damage instance triggering Combo Breaker.
    • If the wielder has above 70% health, the damage is also negated so that their health does not drop below 70%.
    • Does not prevent instant kill effects.
  • Stacks additively with other sources of generic Incoming Damage Manipulation incoming damage manipulation.
    • Affects all damage types the wielder receive, except damage flagged as HP Removal.
    • Other generic incoming damage amplification sources (e.g. Flesh Golem icon Flesh Golem) can be used to counter the effect, causing the wielder to receive damage.
  • Stacks multiplicatively with all other sources of Outgoing Damage Manipulation outgoing damage reduction.
    • Outgoing damage reduction cannot be countered by any other outgoing damage amplification sources.
    • This affects all damage the wielder deals, including damage flagged as HP Removal.
  • This ability's cooldown is bound to the hero. Purchasing the item again does not reset it.
    • It also cannot be refreshed by Rearm icon Rearm.

  • Aeon Disk can be a good choice for tanks, initiators/counter-initiators or supports who have strong defensive abilities.
  • Aeon Disk is effective against heroes that rely on ambush and/or disables followed up by quick, sudden bursts of damage to finish their prey off, wasting their efforts (and possibly lengthy cooldowns), and allowing their target to escape quickly. Such heroes include Nyx Assassin minimap icon Nyx Assassin, Skywrath Mage minimap icon Skywrath Mage, Necrophos minimap icon Necrophos or Templar Assassin minimap icon Templar Assassin.
    • Conversely, heroes that rely on quick bursts of damage may be better off not buying Aeon Disk, as they could waste their own spells upon attempted retaliation.
    • Aeon Disk also provides protection from heroes with strong initiation tools like Earthshaker minimap icon Earthshaker or Magnus minimap icon Magnus, as (most of) their disable durations will be reduced and their team cannot provide immediate follow-up damage to their initiation.
  • Consider purchasing a Blink Dagger icon Blink Dagger or other mobility items with Aeon Disk, as one can use it during Combo Breaker's duration, allowing a quick escape, provided it has not been disabled beforehand. It can also be used to initiate with, protecting you should you either miss your ability or if there are enemy heroes that you missed.
  • Summoned units are not affected by the outgoing damage negation by Combo Breaker. Heroes such as Witch Doctor minimap icon Witch Doctor, Shadow Shaman minimap icon Shadow Shaman or Lone Druid minimap icon Lone Druid can still be able to retaliate on their attacker while being briefly protected.
  • Other protective items like Linken's Sphere icon Linken's Sphere or Black King Bar icon Black King Bar can help delay Combo Breaker's activation in a teamfight, preventing it from being wasted by either a stray spell or a long-distance attack.
  • The item can save a split pusher from getting killed while being far from his team to run back or teleport to base.
  • Aeon Disk might not be a good choice against disables that can't be dispelled like Black Hole icon Black Hole, Chronosphere icon Chronosphere, Static Storm icon Static Storm, Doom ability icon Doom, etc. It can also be dispelled by Nullifier which makes it less effective in the late game.
  • Techies minimap icon Techies mines deal full damage while they are under the effect of Combo Breaker.
