Hi,

My build:
tomb reaver + ardul mephisto + soj

Mercenary:
Pride + fortitude

But my mana is not enought, I should buy a ring ml but will be enought?

Str and dex for gear rest into energy

if u dont have ML on ring/amulet use hex siphon + 2x opalvein +1-3 mana after ea kill

what is better maek o ml?

best is to have +2 warlock skills 15 fcr with ml since not all zones have high density

Use an insight weapon as God told us.

yes you need a source of ml

I dont have enigma, maybe with enigma + ml will be enought

You could switch out your Merc to use insight if you don't want to yourself. Other option is you ditch one SOJ for a nice ring with mana Leech. You need some source of return.
