Battle mage guide

Survivability is important but Battle Mages are pretty hard to die with ok HP and Drain. Less skills casts = more dmg (for ppl who cares about dmg).
I suspect Boss party will ask for Yellow/Dark Aura more than Blue unless party members super weak.

You're still not getting my point. There is nothing better to put the points into. With advanced blue you get an extremely significant passive boost to your resistances, something you won't get by maxing any other skill.

I don't see why it would matter what the boss party would ask for when you can have all 3 of them active at once. Unless you're trying to say that less damage is not really wanted by serious boss runners.
