Priest · Shadow Magic · tier 3 · from level 20 · needs 5 points in Blackout

Improved Psychic Scream

Rank 2/2

Reduces the cooldown of your Psychic Scream spell by 4 sec.

Doesn't change the damage or healing of any Priest spell.

Averages, counting crits and misses, for a level 60 Priest with a typical weapon and no other gear or buffs, against a target your level. Worked out from the game's own data, the same way as the Foresight addon.
