Death Burst. When the magmin dies, it explodes in a burst of fire and magma. Each creature within 10 feet of it must make a DC 11 Dexterity saving throw, taking 7 ( 2d6 ) fire damage on a failed save, or half as much damage on a successful one. Flammable objects that aren't being worn or carried in that area are ignited.
Ignited Illumination. As a bonus action, the magmin can set itself ablaze or extinguish its flames. While ablaze, the magmin sheds bright light in a 10-foot radius and dim light for an additional 10 feet.
Touch. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 7 ( 2d6 ) fire damage. If the target is a creature or a flammable object, it ignites. Until a creature takes an action to douse the fire, the creature takes 3 ( 1d6 ) fire damage at the end of each of its turns.
