Death Mark

(Tome of Battle: The Book of Nine Swords, page 52, DnD 3.5)

Desert Wind (Strike) [Fire]

Level: ; Swordsage 3
Prerequisite: Desert Wind maneuvers
Casting Time: 1 standard action
Range: Melee attack
Target: One creature
Area: Variable spread: see test
Duration: Instantaneous
Saving Throw: Reflex half; see text

As your weapon strikes your foe, his body convulses as waves of flame run down your blade into his body. The fire causes him to briefly glow with a brilliant internal fire before the flames erupt from his body in a terrible explosion.

When you use the strike, you channel overwhelming fiery energy into the body of your foe. In addition to dealing normal melee damage with your attack, you cause fire to erupt from your enemy’s body in a spread. The radius of the spread is determined by the size of the target creature, as indicated on the table below. All creatures in the area, including your enemy, take 6d6 points of fire damage, with a Reflex save (DC 13 + your Wis modifier) for half. This radius is centered on the creature’s position.
You have immunity to the fire damage from your own death mark.
This maneuver is a supernatural ability.

Size	Spread Radius
Small or smaller	5 feet
Medium	10 feet
Large	20 feet
Huge	30 feet
Gargantuan	40 feet
Colossal	50 feet
