Entropic Fist
Entropic fist: [Minor] by Iczer
'My shadow touch has a bite unlike any you have felt before Mr Amazing'
The character can transform a single limb into a obsidian like shard of entropic energy. The limb Inflicts 3d6 damage (no PS bonus) to anything it touches, regardless of immunities or any invulnerable nature, as it corrodes and degrades matter and energy itself.
The limb may be used to parry energy blasts and projectiles at -2 (no action required). In addition, those struck by the entropic limb must make a saving throw (14+ PE bonuses apply) or lose 1 PE point from wasting flesh ( inanimate objects lose 1 AR instead) Lost PE recovers at a rate of 1 per day. SDC/HP damage done by this attack heals at 1/5th normal rate.
The character however is not immune to his own power. every time he assumes an entropic limb, he takes 1d4 damage himself +1 for every minute of it's use. this damage heals normally however.
