The skill Arrow Nova from Dead Eye is currently not effected by minion cooldown recovery speed.
Reaped the Damned says the Abominations Melee attack is replaced by Soul Reave but it isn’t, it’s a skill with a cooldown that won’t scale with the abominations attackspeed. The abomination still attacks normally between casts.
The Abomination seems to miss with the initial slam of the Skill Tail Slam from Bloated Corpse, likely caused by the increase in the abominations base attack range recently.
