Temper's Flames

Invoke flames to burst from the weapon you are currently holding in your other hand (must be light or versatile)

The weapon ignites and emits dim light at a 10 feet radius and deals 1d6 fire damage on successful weapon hits while this spell is active

The weapon deals this damage 1d4 + 2 times after these charges are expended or the sword is no longer drawn or in your possession the spell ends

At higher levels: per 2 spell slot levels used increase charges and damage by 1d4 and 1d6 respectfully and increase the light cast by 10 feet (the last level's light radius becomes bright)
