I've found Linu to be pretty good because she'll do the healing thing, plus the occasional useful zap of undead critters. But I swear, the only reason I get into half of these chests is because I have the gloves which give me some electrical damage, which is the only damage either of us does, and that's teeeedious.

I got to the beginning of Chapter 3 and shut it down last night before lioncub killed me. ;-) Am looking forward to Undrentide and Hordes (I bought the gold edition that includes Undrentide and lioncub bought me Hordes before he realized what a time suck this was going to be for me *grin*).
