Invert Vita (3.5e Maneuver)

''You strike the opponent and corrupt their life force. Suddenly the healthy hydra began looking ill, as you watched as it began to rot before your very eyes.''

The body heals naturally through the normal regulation of life energy through it. Those whose life force has been disrupted, or do not even have natural life forces such as golem, cannot heal naturally. You go one step further, and reverse the natural healing, turning it into something baneful. As a standard action you may make a melee attack and deal damage as normal. In addition they must succeed on a Fortitude save DC 18 + Wisdom modifier, or have their life force corrupted. They cannot heal, all magical attempts at curing them fail to function unless they succeed on a caster level check with a DC equal to 10 + your initiator level. Any fast healing or regeneration they possess is reversed, causing them to lose that much hit points every round (which, for regeneration, is treated as the bypassing damage type). Thus effect lasts for the duration of the maneuver. A successful save negates the inversion effect, but not the damage.

If the target is already under the effects of Invert Vita, employing the maneuver again may do one of two things. You may dispel Invert Vita on the target (usually used for allies, and with a melee touch attack so not to cause damage), or you may aggrivate the target's natural healing abilities, dealing your normal melee damage +1 point of damage for every HD of the opponent. Invert Vita does not work on creatures that no not heal naturally, or at least possess some form of fast healing (allowing you to target undead and constructs with the fast healing ability, even though most are immune). A successful save negates the additional damage, but not the initial damage from your attack.

This maneuver is a supernatural ability.
