Oh, finally a better unholy melee tree
By better i mean actually freaking playable.
Passive skill in place of the black sleep is propably a bit boring but i'll take anything over what is propably the worst skill in the game. That was sitting on this tree for over 10 years.
The thing is, you made the whole build scale to vitality but you still need mana to use your abilities. It screams bloodmage mechanics on this one. Mana is disabled, using your offensive spells incurs blood-hatred like life drain that gets stronger every base level. You have your Life on Attack skill to counterbalance this. For generic spells like VOJ, DA etc, mana cost is set to 0 if you have grim presence enabled.
