I'm really enjoying this, I've been playing the flame wizard and I think I'm finally getting the hang of her especially since I swapped to a beam staff and the pyromancer route.
I was finding that my bolt staff was too ineffective (slow moving projectile meant my team mates were getting all the distance kills), and the flamethrower type staff was too close range, instead I'm using the beam as a mid distance sniper and flamethrower type weapon so I can start firing up the mobs before my team get into close combat then cool down a little whilst waving my bright red sword around.
We've done a few runs now where we've got one of the tomes and two grimoires.
