Cast Sight was changed so it can stack with Shissar.
Song of Midnight was changed so it will speed up enemies.
Song of the Deep Sea's effect text changes.
Feast of Blood (Vulak dagger) proc change from DD to DoT happens in Oct01 instead of Nov01.
Harvest of Druzzil (A PoP-era wizard AA) got some changes?!
