Avenging Cubic does not remove debuffs ...or not triggers to remove targets buffs , and a bug summon pet Vampiric Rage from damage inflicted .... devs should check this ... summon has better hp regen then VR from damage inflicted ....
Actually, it's been 2 years that Wynns are complaining about Avenging Cubic not working properly before lv 95. Some of them were smart enough to keep Smart Cubic.
