Unfortunately, my character died from blood loss due to the aforementioned bug. I'll send the screenshot over.
EDIT: I'll see if I can reproduce it.
I'm 100% sure the spell type was user. It's very inconsistent though. Sometimes, when the mob hits me, the fire damage text appears in the message box, but I check my limb health and I received no extra damage.
EDIT: Would add a screenshot but itch.io doesn't like mine for some reason
The spell, flre aura, seems to bug out sometimes.
-If you cast fire aura, make a new attack and use it, the added fire damage won't apply
-Fire aura randomly applies itself to mobs. I nearly got chunked out by a kobold archer because his shot did 20 extra fire damage
