fun idea i had: wool constructs

[TBeholder]

use possession to dig out if the owner is unconscious

Oh, right - already was done:

‣ Rumored and storied powers of Andrathath's Mask include:
[...]
the ability to possess and animate the unconscious body of its wearer (but only to flee from danger);
- Cormanthyr: Empire of Elves

This is asking for someone to design a Pinata golem.

Why not. But what will it spill if damaged? Hmm... Lots of smaller constructs?
