WD, Produce Lightning is good for 3 minutes if you only use it as a melee weapon (which I've been assuming Ape is doing), so it should be good for a while yet.
Healing aside from stabilizing tends to be ok at best. But I could do a Cloistered Cleric and with the DMs consent use the reserve feat Healing Hands from Complete Champion to be able to keep the whole party at their feet for a while.
I'll start putting a concept together and see what I can come up with.
