Made of fiery smoke coalescing into a vaguely humanoid shape, a firegeist is little more than wisps of black smoke and spots of brighter flame.

Elemental Echoes. When a fire elemental meets its destruction in a particularly humiliating fashion while summoned away from its home plane, what returns is a firegeist. Malevolent and resentful, less than their former prideful selves, they exist for revenge.

Indiscrimate Arsonists. Firegeists are not adept at telling one humanoid from another, and so burning any similar creature will do, providing it is flammable.

Brighter Light, Darker Smoke. A firegeist can shine brightly or be primarily smoky and dark, as it wishes. It always sheds a little light, like a hooded lantern.

Elemental Nature. A firegeist doesn’t require air, food, drink, or sleep.

Hide By Firelight. In an area lit only by nonmagical flame, a firegeist gains a +2 bonus on Stealth checks. This becomes +4 when hiding within the fire.

Illumination. The firegeist sheds dim light in a 30-foot radius.

Magical Light Sensitivity. While in magical light, the firegeist has disadvantage on attack rolls and ability checks.

Water Susceptibility. For every 5 feet the firegeist moves in water, or for every gallon of water splashed on it, it takes 3 cold damage.

ACTIONS

Multiattack. The firegeist makes two slam attacks.

Slam. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 7 (1d6 + 4) bludgeoning damage.

Combustion Touch (Recharge 5–6). The firegeist may ignite a target when making a slam attack. The target must immediately succeed at a DC 13 Dexterity saving throw or catch fire, taking an additional 5 (1d10) fire damage at the beginning of its next turn. Until someone takes an action to douse the fire, the creature takes 5 (1d10) fire damage at the start of each of its turns.

But this is where we must stop for now, my friend. My mind, it wanders so at times. Do come see me again, though, for more of the wonders and surprises of Midgard. (OGL)
