Notes
  • While charging, Arcanopulse can be interrupted by any hard disables.
  • Arcanonopulse's cooldown starts after firing the beam or after it's cast time ends if not fired, not while channeling.
  • Once casting, Arcanopulse cannot be interrupted. During the cast time, Xerath will ignore crowd control effects but still suffers from them if the duration persists.
  • If Xerath is displaced by a knockback or pull effect during the cast time, the beam will fire from the original point of casting.
  • If Xerath dies while charging or during the cast time, Arcanopulse will not fire but is still placed on cooldown.

Ability Details
Notes
  • There is an 0.2 second casting time that must be completed in order for the impact to deal damage.
    • Cast times cannot be interrupted by crowd control effects, and will only be interrupted by Xerath's death. If Xerath dies during the 0.2 seconds, the impact will fizzle after the 0.5 seconds (and will not deal damage).
    • During the cast time, Xerath will ignore crowd control effects but still suffers from them if the duration persists.
    • If Xerath is displaced by a knockback or pull effect during the cast time, Eye of Destruction will still go off at the target location even if he is no longer in range.
  • The outline of the area of effect will appear the moment Xerath begins casting, and deals damage after the 0.5 delay. After the 0.2 second casting time, there is no way to stop the blast.
  • Eye of Destruction grants sight over a large area on-cast, which persists for a short duration after the blast hits.

  • Arcane Barrage has a 0.8 second cooldown between casts, not affected by Cooldown Reduction.
  • Each cast of Arcane Barrage grants a brief area of sight.
  • Each cast is classified as an activation for the purposes of effects such as Tear of the Goddess item Tear and Spellblade
  • Xerath can use Dark Passage Dark Passage while rooted.
