Notes
This spell will raise the strength of undead targets in addition to healing them but it only affects targets that fit the standard hostile targeting scheme. This can be useful to buff summons or shifter allies, if the PvP setting permits targeting them with hostile spells. Passing the saving throw only cuts the damage in half; it does not negate the strength damage.
