Since there doesn't seem to be anything in the rules (short of potions and spells) for regaining HPs for Wizards (and only said potions and spells for non-wizards; a wizard can't heal himself), it is my opinion that there's something missing in Deathmaze. Not to worry; I have confered with another DM fan and we have created this house rule:
The Paolo Rule
"A player character gains 1 HP for every 3 hours of rest. In game turns, the player takes a turn to rest (do nothing). For every turn taken resting, the player(s) must check once on the Wandering Monster table. If a WM appears, the monster's Combat Round precedes the player's Combat Round UNLESS a player is "Posted Guard". Guarding Player Characters do not receive the HP benefit of Resting."I particularly like the guarding bit.
I will have another turn ready for posting tommorrow night; I'm in class all weekend.
