Ghostly Flames
(2) Is there anyway a player could get them at some point? [Racial ability, God ability or Fixed Art]?
(3) I say racial, god or Artifact BECAUSE a Necro/Fire Spell would be...mostly useless (most player summoned undead cannot be healed) and maybe too powerful for those it is useful to (For undead it could be used as Lesser Self-Healing or a Much faster Regen, depending on how long the Ghost fire cloud lasts.)
[Start discussion.]
Not in GDD, because trying to start a discussion and not yet ANY kind of specific proposal.
