Blue Blood (3.5e Maneuver)

Creatures slain this maneuver have a ghastly blue hue to their skin, and their faces warped in the terror of suffocation.

Make a melee attack. In addition to the damage the creature must make a Fort save or lose all the oxygen in their blood. For the next 1d4 rounds they take 50% of their maximum hp in damage unless they spend a full round action to catch their breath each round. A successful save negates the suffocation effect, but not the melee damage.

Creatures which don't breathe are immune to the suffocation effect of this maneuver. This maneuver is a supernatural ability.
