Abyssal Blast (Su): Once per day a death knight can unleash a blast of eldritch fire. The blast fills a 20-foot-radius spread anywhere within a range of 400 feet + 40 feet per HD of the death knight. The blast deals 1d6 points of damage per HD of the death knight (maximum 20d6). Half of the damage is fire damage, but the rest results directly from divine power and is therefore not subject to being reduced by protection from elements (fire), fire shield (chill shield), or similar magic. A Reflex save (DC 10 + 1/2 death knight's HD + death knight's Charisma modifier) reduces the damage by half.
Reflex save (1d20+9)[16] Ethereal man
Reflex save (1d20+6)[13]7 fighter/archer/caster types
death knight damage (18d6)[61] Half of the damage is fire damage
