Burning Jealosy

While raging, upon dealing fire damage to a creature, you light them on fire. While on fire, the creature takes 5 fire damage at the start of their turn, ignoring resistance to fire damage. The creature remains on fire until it or another creature uses their action to put it out, or if they end their turn in water.

Additionally, you’re always aware of any fires within 30 feet of you, including through solid surfaces.
