60 / 90 / 120 / 150 / 180 (+ 60% AP)

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.
Active:Xerathroots himself to his current location for up to 10 seconds, gaining the ability to cast Arcane Barrage multiple times, but losing the ability to cast his other abilities.

Rite of the Arcane has a short activation time where Xerath ascends into his true form. During this time, Arcane Barrage cannot be activated and a circle indicating the ability's maximum range appears (starting small and rapidly expanding to the maximum range over the cast time).
The maximum-range indicator is visible to both allies and enemies.
