Wehostan, son of Bardolf:
Oh man, THAT is a great idea for a high level monster! Instead of level drain, it gives you levels when it hits you, but if you go over the maximum level for the rules in question*, you die! Talk about a risk-reward situation for the approaching max level characters! And those at max level (14 in BX, 36 in BECMI, 20 in all WOTC editions, LL, BFRPG) would run screaming in fear...
I think you'll find the more
argumentative litigious gamers would start angling for divine accession for their characters, but it still takes them out of the game.
Glad you got the heating fixed, can't imaging dealing with -25
o in either system without heating.
