Smite the crap out of them. Or have someone code a smite-like ability for you. I think Twist had a cool/unique smite echo. (Or maybe that was just for the twist going crazy/returning event).

Especially if it takes half their hp/mana/mv it shows them that they are not a powerful as they *Think* they are. It is a warning after all. Like certain imms would probably impale/cranial/pincer/punt you if they tried that. For lower level people a warning smite might be needed. I really think mortals should fear immortals (especially how powerful battle imms or evil imms).

Of course, serious rules errors are handled the way they should. But that is OOC so yeah.

Again, this is just my opinion. And I like Tac's ideas for punishments.
