Ouch
Turns out I'm not a very good scout. We back-tracked some to make sure we didn't leave anything in our rear. I shifted to a spider to investigate what seemed to be an overlook used for dropping boulders on would-be attackers. Things were going well until I awakened a passel of what I think were gargoyles. Trapped on the ceiling, 3 of them beat the crap out of me forcing me to fall to the hard, snow-packed ground far below.
After that, I tried to cloak myself in invisibility to sneak away, but the snow gave away my footprints, and the beat down continued. Eventually I had to shift into a tiny spider and invisibly scurry up the wall to confound my pursuers whilst my colleagues won the battle on their own.
After a quick rest, we pushed back down stairs where once again my attempts to scout ahead got us surrounded by yetis. We wiped out the yetis, but appear to have awoken a frost wyrm of some type and an alpha-yeti that is even larger than the small guys.
Yikes.
