Vampiric Touch drains hit points from the target and temporarily adds them to the caster.
|“|| Vampiric Touch|
When this spell is cast, the target loses 1d6 Hit Points for every 2 caster levels, to a maximum drain of 6d6 for a 12th-level caster. These Hit Points are added to the caster's current Hit Points, with any Hit Points over the caster's normal maximum treated as temporary additional Hit Points. The temporary Hit Points last for 1 hour.
Note: This spell may not be cast multiple times to radically increase the caster's Hit Points. The caster must wait for the first Vampiric Touch spell to run its course before casting another.
