Continuous Cure Wounds (3.5e Spell)
From D&D Wiki
|Casting time:||1 Standard action|
|Saving Throw:||Will half (harmless); see text|
|Spell Resistance:||Yes (harmless); see text|
When laying your hand upon a living creature, you channel positive energy that cures 1d8+1 points of damage every round for a number of rounds equal to your caster level (max 10).
Since undead are powered by negative energy, this spell deals damage to them instead of curing their wounds. An undead creature can apply spell resistance, and can attempt a Will save to take half damage.
