I got torches
Well I believe you need a full round action to get the torches, then light them then either throw them (which will probably make them puff out after a time) or hit them.
They are also improvised weapons so that -4 to hit.
I mean if you can drop the 1 troll, and can keep them from getting up which they will due to regeneration and use the acid or torch to go through their HP...well...your golden! It'll be interesting.
