All fire spells have the same fire aura when casting except Flare. Flare for some reason has an Unaspected cast aura, the same as Foul. The rainbow effect at the caster's feet is typical for spells like Ruin, Clemency, Miasma, Foul, Holy, etc. Despair is a single target version of Flare yet even that has a Fire red aura at the caster's feet. Is this just a 8 year unnoticed bug?
