Soulspike Revenge (3.5e Maneuver)

As your enemy slices you with their sword, spikes pop out of your chest and stab them in the arm.

Immediately after an opponent hits you with a melee attack, you may spend some essentia and initiate Soulspike Revenge to deal 1d4 points of slashing and piercing damage per initiator level to your attacker. If the attacker fails their Reflex save, they also take 1 point of Strength damage and Dexterity damage per point of essentia you spent on Soulspike Revenge.

This maneuver is supernatural.
