Both characters in post #4357867 have flames floating above their heads.

What tag best describes them?
Maybe:

• halo (doesn't look like a flame, but the idea behind it is similar)
• wisps
• magic wisp
• paranormal wisp

edit:
Smooshkin calls them crown_flame
But I'm looking for a more general term.

I would go with nimbus(not currently a tag) for supernatural head adornments, aura/aureole for the full body version, and make halo and crown_flame imply nimbus. Or, alias halo to halo(nimbus) to seperate further from the halo game series.

I would also make Sims gems imply nimbus, and other overhead indicators like quest markers, when applied to a character.

So

Would qualify for the nimbus tag too
