Shadowshield

This spell enables a wizard to make a creature more likely to survive an attack by imbuing the creature with a phantom shadow of itself.

This phantom possesses half the creature's normal hit points. When the creature struck by an attack, there is a 60% chance that the phantom absorbs all the damage. The shadowshield is ineffective against psionic or magical attacks that affect the mind.

The phantom makes saving throws just as the affected creature. If reduced to 0 or fewer hit points, the shield is dispelled and cannot be received again until one day has passed for each point of damage the phantom has taken. A creature attempting to use this spell more than three times per year must make a successful Constitution check or lose one point of Constitution.

The recipient's shadow must be visible at the time the spell is cast or the spell fails.
