Thanks Almerin for the quick reply. Your answers were definitely helpful!
I'm not sure if this is considered meta-gaming (around our tables it's not so...), but I have a couple suggestions for you, Brianna and Dragon Mistress. You definitely don't have to go with them... I'm not even sure how well they'll work. Anyway, take them for what they're worth.
I noticed Tami has flare and ghost sound on her spell list, as well as silent image. Any one of those three could turn out to be a great distraction.
Also, Tami has Comprehend Languages. Maybe cast that and see what these two are talking about. That might help us understand what's going on here.
The only problem I see with using any of these spells is I'm not sure how much noice Tami needs to make to cast them, seeing as she is a bard and all.
Our ranger friend has an Entangle spell. Does that work underground? That may prove helpful, though I find entangle spells dangerous in that they can trap friends as well as foes really easily.
I also have a Levitate potion which I have no qualms about using if I need to get out of a tight spot. How tall are the ceilings here, Almerin? Is that posted somewhere? I'll go back and check.
Anyway, some thoughts of mine.
