Heated Soul

When wielding metal weapons, your internal heat allows your attacks to deal additional damage. As a bonus action, you may flare your internal heat. Any metal weapons you wield deal additional fire damage equal to your proficiency modifier on a hit. Additionally, anyone trying to wield one of your weapons within 1 minute of you releasing it while under the effects of this ability suffers fire damage equal to your proficiency modifier each turn. This effect lasts for 1 minute, or until you lose concentration
