Healing Spell Nerf (3.5e Variant Rule)
From D&D Wiki
Healing Spell Nerf
When a character is below 0 hitpoints, spells with the Healing descriptor do not affect the character normally. These spells are treated as if each die rolled was a 1 and they do not stabilize the target. If the character's hitpoints are increased to 0 or greater, they are treated as "bleeding" and lose 1 hitpoint per round until they are stabilized.
Fast healing does not stabilize wounds until a creature's hitpoints are increased to at least 0.
A cleric that channels positive energy may make a free heal check to stabilize whenever they cast a healing spell.
