Cloak of Gaer

This powerful spell surrounds the protected creature with a faint magical aura. It takes effect (days or perhaps years later) when the being it is cast on must make a system shock survival roll, or when the being reaches 6 hit points or less. It can be cast on a just-injured being. When either of the triggering conditions occurs, the following happen:

A system shock survival roll, if required, is automatically successful, regardless of the creature's Constitution.

The creature regenerates severed or missing limbs or body extremities.

The cloak purges the body of all poisons, diseases, insanity, charms and outside mental influences, curses and geas effects, possession or symbiotic life (even if friendly and desired), and feeblemindedness. It also cancels the effects of forget spells previously cast on the being;

The creature is restored to full wakefulness, alertness, sobriety, and a pain-free state.

The cloak heals 4d8 hit points of damage.

If this spell is cast on a hurt creature within 2 rounds of an injury major enough to activate the cloak, the spell has the effects noted above, and allows a being who has failed a system shock survival roll a second chance. This roll is made at a +22% bonus. Failure means death occurs, but the purge and regenerate effects occur to the corpse.

If this spell is applied 3 to 9 rounds after a being has been stricken, it allows a second system shock survival roll, but without any bonus; other spell effects occur as noted here. If the spell is applied later, it only purges and regenerates (even on bodies).

The spell's material components are four drops each of holy water, the caster's blood, and dew. A dispel magic cannot end this spell if it has not been activated. This magic has enabled many dead drow to return and hunt down foes. Certain drow wizards are rumored to use a similar spell.
