Bog Burner (Mature Methanosian)

Climate Adaptation: Bog Burner can vitrify his cells to prevent freezing, granting him immunity to cold damage and the effects of extreme cold.

Regeneration: Bog Burner regains 10 hit points at the start of his turn if he has at least 1 hit point.

Plant Camouflage: Bog Burner has advantage on Dexterity (Stealth) checks made to hide in forested or overgrown terrain.

Methane Production: Bog Burner can produce and ignite methane at will. As a bonus action, he can ignite methane in a 10-foot radius, dealing 3d6 fire damage to all creatures in the area (Dexterity save DC 16 for damage)

Multiattack: Bog Burner makes three attacks: one with his Slam and two with his Thorn Blades.

Slam: *Melee Weapon Attack*: +8 to hit, reach 5 ft., one target. *Hit*: 15 (2d8 + 5) bludgeoning damage.

Thorn Blades: *Melee Weapon Attack*: +8 to hit, reach 5 ft., one target. *Hit*: 12 (2d6 + 5) piercing damage plus 7 (2d6) fire damage.

Explosive Seed Pods: *Ranged Weapon Attack*: +6 to hit, range 30/60 ft., one target. *Hit*: 18 (4d6 + 4) fire damage. The target and each creature within 5 feet of it must succeed on a DC 16 Dexterity saving throw or take 9 (2d8) fire damage.

Chlorokinesis: Bog Burner can use his chlorokinesis to control plants in a 60-foot radius around him. As an action, he can cause one of the following effects:

• Create difficult terrain with entangling roots and vines.
• Cause a tree or plant to attack a creature (as if it were using the Thorn Whip cantrip, spell save DC 16).
• Heal himself or another plant creature for 10 hit points.

Methane Burst: When Bog Burner is hit by a melee attack, he can use his reaction to release a burst of ignited methane. The attacker must make a DC 16 Dexterity saving throw, taking 14 (4d6) fire damage on a failed save, or half as much on a successful one
