Infernal Pawn (Ex): At 1st level you gain Fire, Cold, and Acid Resistance equal to twice your Charisma modifier, the Cold and Acid Resistance are capped at 10 (gained at Charisma +5).
Imposing Presence (Su): Beginning at 3rd creatures suffer a penalty to hit you equal to your Charisma modifier. Once a creature has successfully struck you this penalty does not apply to it for 1 hour. This is a mind-affecting effect.
Vile Blows (Su): Beginning at 7th level whenever you use a martial strike against a creature which is not Lawful Evil, Lawful Neutral, or Neutral Evil you add your Charisma modifier as bonus damage. This bonus damage is Vile damage and is resistant to attempts to heal it (see Book of Vile Darkness).
Words of Corruption (Su): At 11th level you gain the ability to whisper Words of Corruption 3 times per day. When you use this ability make a Diplomacy check to alter a creature's attitude of you (at no penalty for being rushed). The target must make a Will save (DC 10 + 1/2 your Warblade level + your Charisma modifier + 1 per 5 points your Diplomacy check beat the DC for Helpful). If they fail the moral axis of their alignment changes to Evil and they regard you with the new attitude regarding their former allies with an attitude 1 step worse per step their attitude improved towards you. This change to their attitude and alignment both last for only 10 minutes per 2 Warblade levels. This is a language-dependent, mind-affecting, charm effect. Using this ability is a standard action.
Know Your Place Worm (Su): At 15th level you gain the ability to inflict negative levels with your martial strikes. Whenever you make a martial strike you may choose to inflict 1 negative level on any creature you successfully hit as part of it. If a strike allows you to hit multiple creatures this negative level applies to all of them, but no matter how many times you hit a creature it suffers no more than 1 negative level. You may only use this ability a number of times each day equal to twice your Charisma modifier.
