Yeah but it's usually because they are fire weilding lunatics
We once had a D&D campaign that resulted in the rest of the party going on a quest and leaving both the Mage and Sorceror chained up behind because they were such a hazard to the players
(The quest was to attains the materials to make rings of fire immunity)
One of them also had a curse placed upon them so they could only cast magic missile when in the boundaries of the city we all resided in by the city council because in a effort to stop one their he cast fiery inferno on a thatched roof
But - I'm not really feeling in the mood to execute anyone, ya know? Just got back from the gateway of the Eye. Had a rough time with some Eldar. And now I'm just wantin' to chiiiiiiiill, man.
I'm sorry to keep y'all waiting! It will be up tomorrow; had a few paragraphs in and for some reason my internet timed out. Starting from scratch, it'll be sometime tomorrow morning.
