And it's a TN Huge Magical Beast. That might be worth checking, if someone has access to that sourcebook. A high enough strength might justify the tower scene, and maybe even the stomp. No idea how it looks like, appearance-wise.

EDIT: Found this blurb:



Not sure if we're allowed to copypaste that kind of stuff, so if that's a breach of copyright, let me know and I'll take it down.
You haven't pasted anything that isn't easily covered under Fair Use. Very interesting power set....

Would Rich have strayed outside stock AD&D for the source of MitD?
