Too late. When he was done erasing all his furniture, he just walked through the bars of his cell. By walked I of course mean that he ripped them out with less effort than it took him to reduce his table to dust. I've locked the doors and am now walling him in. HE MUST NOT ESCAPE! I notice though that once he starts breaking furniture, he doesn't stop when he changes back to a dwarf. That kind of behavior pisses me off. I might just change my mind about keeping him alive if he keeps doing that. That gives me an idea...
[edit] he did it again
NEW PLAN!
My miners have been ordered to excavate the earth around the building holding the werechameleon kogsak, taking special care not to breach his basement quarters. this is a special project, handed down by the mayor himself. the stone beneath the structure is to be dug out and removed, creating a deep bore in stone, and pillars built beneath kogsaks prison. When the bore has reached sufficiant depth, a lever will be pulled, and kogsaks prison, along with the vandalistic werechameleon himself, will plummet into the depths to be dashed into oblivion in the darkness below. I only wish I could see it in slow motion.
question, will this actually kill kogsak? considering how dwarf fortress works, I have my doubts. I know constructed stuff deconstructs when it collapses, but im not sure if the natural stone of the basement will collapse and smash him or if it will protect him.
[edit edit] he has escaped.
