Darkray's Strength of Life
(Necromancy)

Range:  0
Components:  V, S
Duration:  1 turn + 1 round per level
Casting Time:  5
Area of Effect:  The caster
Saving Throw:  None

With this spell, the caster can alter his Strength to any value between 6 and 25 inclusive, but greater than his current Strength. In order to do so, he must sacrifice (at the beginning of the casting) a number of hit points equal to difference between his current Strength and the Strength he wants.
While under the influence of the spell, the caster gains almost all benefits from the altered Strength. He does not gain any extra attacks, though.
