Reverse Cure (3.5e Spell)

If the target fails its Will save, effects that would cause it to gain health during the duration cause it to lose that much health instead. The same goes for effects that cure ability damage and drain, as well as negative levels. Curing a disease or poison causes the disease to inflict damage one more time or poison to inflict secondary damage. Raising the target from the dead utterly destroys their body instead. In the case of curing damage, ability damage, ability drain, or negative levels, the damage, drain, or negative levels inflicted by any one effect cannot be greater than the quantity of damage, drain, or negative levels they are currently suffering from.

If the target succeeds on its Will save, it does not have healing effects reversed, but does not benefit from healing of any of the above sorts.
