Fire Elemental

At the end of each of the monster's turns, each creature of the monster's choice in a 10-foot Emanation originating from the monster takes 10 fire damage. Creatures and flammable objects in the Emanation start burning.

The monster can move through a space as narrow as 1 inch without expending extra movement to do so, and it can enter a creature's space and stop there. The first time it enters a creature's space on a turn, that creature takes 10 fire damage.

The monster sheds Bright Light in a 30-foot radius and Dim Light for an additional 30 feet.

The monster takes 3 (1d6) Cold damage for every 5 feet it moves in water or for every gallon of water splashed on it.

The monster makes two Burn attacks.

Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 2d6 + 3 fire damage. If the target is a creature or a flammable object, it starts burning.
