Candlecap

After imbibing this potion, you gain lively flaming locks, which last for 1 hour and shed bright light in a 20-foot radius and dim light for an additional 20 feet. Once on each of your turns for the duration, you can cause an unarmed strike made with your head to deal an extra 1d4 fire damage. Additionally, you can take an action to cause the flame on your head to flare up and burst outward, dealing 2d4 fire damage to all other creatures within 5 feet of you; using this ability causes the effects of this potion to end early.
