Necromancers' useless trait "Reanimator"
Enemies don’t rally on pet/minion/summon kills, and the jagged horror at higher levels lives long enough to do some damage. Play necromancer to level 80 before you judge things like this.
It’s a pretty lousy trait, I’ll agree, so I’d prefer if it just offered some ability to toggle whether it turns on or not, and to remove the degeneration, putting a max jagged horror cap at 5.
Main point of Jagged Horror is to be paired with the Death Nova trait for a fast and cheap trigger. But yes it’s pretty annoying if you have just 10 points in Death Magic to make staff more useful.
