A runestone made by an Dragonborn runesmithy with the glyph for the Fire. Equipping and removing this runestone with a Runekeeper (Occupation) check, removing this rare runestone from a weapon will most likely guarantee its destruction. Any weapon or item this rare runestone is put on will require attunement to check the strong magics within. 

This runestone is a Firerune that when equipped to a weapon the glyph allows it to deal an additional 1d10 Fire damage +1d10 Fire damage for every level of spell put into it upon creation. 

This complex runestone has 3 charges that fully recharge every long rest. One charge can be used to alight the sword in flame that lasts 1 hour and sheds bright light in a 15-feet radius and dim light in additional 15-feet. The flame ends if the weapon is dropped, sheathed, or if the user dismisses the fire using a Bonus Action.

Notes: Damage: Fire
