Phoenix Blast

At 16th level, if a flamewarden dies, his body explodes in a conflagration in a 20-foot spread. Each hostile creature in the area takes 10d6 points of fire damage unless it succeeds at a Reflex save (DC = 10 + half the ranger's level + his Constitution modifier) for half damage. The flames don't harm the flamewarden's allies, who instead are healed 5d6 points of damage, and any poisons they are currently suffering are neutralized.
