Thanks dude... Also Steam Forums people said this:
Apparently it does boost anything in Necromancer skill tree besides boosting Reaper form attacks.
Sweet. Now I know.
Because now I'm going to boost as much as possible into Arcane and Gift Found. Also Grim Talisman is useful because thankfully that helps collect Reaper Energy a lot.
I like the Ghouls doing all the dirty work while I admire the graphics and use heavy weapons.
Not a fan of dodging.
