Yup. Only my essentials were in my car, fortunately.
A gaunt, long-limbed creature skuttles into the arena and up the southern wall, using long, spindly fingers to cling skillfully to the masonry. The thing's skin is rough and grainy, studded with patches of needlelike protrusions, and its bulbous head is topped by a veritable forest of thorns. A thick, barbed tongue lolls out of its devious looking mouth as its beetle-black eyes dart wildly about the arena.
The splinterwaif enters the arena at 0N0E and attempts to mount the wall and run to 0N30E20Z, where it will launch a splinter at the astral construct. If it fails the climb check (Climb +13), then it makes another attempt to move to the same location.
