I was wondering how to sustain mana in single bosses fights? Because i'm draining my 4k mana by widowmaker in 5 seconds. I have 30% mana leech but obviously it's not enough at all.
Also is there a way to increase accuracy (aka attack rating) because right now i have something like 45% chance to hit which is okay for trash mobs but it looks like i'm missing bosses all the time and fighting boss on Hell difficulty takes ages.
