Fire spirits touched by death, ghostflames resemble torso-sized orbs of flickering blue-green fire. Constantly surrounded by a nimbus of pale greenish light in addition to their own fires, ghostflames occasionally spawn small subspheres that orbit incessantly or drift away to investigate the ghostflame's environment. Bitter creatures that loathe the taint of death inside them, ghostflames hunt undead creatures obsessively and may aid any who plan to fight against the walking dead.

Ghostflames attack with gouts of fire extending up to 15' away, or else with a subsphere; regardless of the method used, each attack inflicts 1-8 hit points of damage and sets the target alight on 2-in-6. Against undead creatures -- or any who habitually wield necromantic power -- a ghostflame's fires inflict double damage.

A ghostflame may also attempt to take over a target, melding with its chosen "mount" in a form of possession. If the target fails a save vs. death ray, the ghostflame takes control of the victim, granting a controllable flame-aura that inflicts 1-4 hit points of damage but forcing a Wisdom check whenever the victim wishes to act independently. A ghostflame may be driven out with the appropriate rituals or clerical magic.

Ghostflames are immune to fire and to non-magical weapons. They may be turned as undead of their Hit Dice.
