Simple little icon made in paint.NET, bordered using borderizer. Use with credits to Modo.
I think it looks good in-game, but I also made it for a reason. It is more freehand than anything, as you may be able to tell. I no longer have the original .jpg so I cannot make a passive, autocast or upgrade version.
If you cannot tell what it is, it is an exlamation mark in front of a fire.
