Resurgent Transformation grants you the ability to recover from deadly wounds with restored vitality and a will to fight, but at a price. Once cast, resurgent Transformation lies dormant for up to 1 hour per level until you are reduced to one-quarter Hit Points or less. Once triggered, you immediately gain a +4 enhancement bonus to Constitution and Strength, Damage reduction 5/—, and the benefits of a haste spell. In addition, you heal 4d8 points of Damage + 1 point per Caster Level (maximum +25).

The advantages from your Transformation persist for 1 round per Caster Level after the spell is triggered. Once the spell ends, it takes a heavy toll, leaving you exhausted and inflicting 1d4 points of Constitution Damage. Utilizing more than one resurgent Transformation in a day is particularly risky. The expiration of a second resurgent Transformation in a 24-hour period inflicts an additional 1d4 points of Constitution Damage and results in death from system shock unless you succeed at a DC 15 Fortitude save, made after the Constitution Damage has been applied.

If the spell expires or is dispelled before the Transformation has been triggered, no adverse effects result.
