Use one of those stone icicles

Your attention starts lingering to the roof of the tunnels; they're littered with pointed stones just begging to be launched. You quietly speed ahead of the shambling heroes, almost bored from the lack of encounters. You'll give them an encounter all right.

You gaze intently over the spikes, seeing which of these unappreciated **** machines would be your lucky XP benefactor. Finally you land your beating bulbs on a spike with not much stone left to attach it to the ceiling; perfect. You use your sharpened claws to attempt to climb the walls of the tunnels, which was more difficult than thought out. With a pretty pitiful undertaking, you still manage to make your way to top of the cylindrical structure, and you find yourself facing natures made marvelous spear... "Yer little lustful lassies would never drink without a pint, and if the liquor ain't too powerful she never spend night..."

The Bard's obnoxious tune makes your appreciation for your find more and more nerve racking, as time was cut short; too short. You take you claws and slam them into the mediocre crack just big enough for both of your paws. You're not sure if all of your strength would do it, but your only other option now is too let the group pass and just wait for them to come back through or watch for another to come through these parts. It's literally now or nothing.
