My Bard and Shadow heart we're easily able to wipe out three intellect devourers and we're practically right on top of them.
In another thread, The_Red_Queen pointed out that in this patch enemies seem really unobservant of arrows and bolts hitting them from unseen sources, which I've experienced as well. [edit: and in this thread while I was writing this, lol]
I think another factor here is how much we've been playing this game - how many times have you fought those intellect devourers with SH? Probably at least twice with every available class? I think it's really easy to cheese things when we're super familiar with how every system works. That encounter is now trivial, but of course the first couple of times I played it, almost two years ago, I got wiped out in a hurry.
