Torch Slug (5e Creature)
From D&D Wiki
Small ooze, unaligned
Skills Stealth -1
Burning Body. If a creature is grappling the torch slug, that creature takes 7 (2d6) fire damage at the start of the torch slug's turn.
Fire Absorption. Whenever the slug is subjected to fire damage, it takes no damage and instead gains a number of hit points equal to the fire damage dealt.
Spider Climb. The slug can climb difficult surfaces, including upside down on ceilings, without needing to make an ability check.
Slam. Melee Weapon Attack:: +1 to hit, reach 5 ft., one target. Hit: 1 bludgeoning damage, plus 3 (1d6) fire damage.
Invoke Flame (Recharge 5-6). The torch slug erupts with magical fire that gushes in every direction all around it. Each creature in a 10-foot sphere originating from the slug must make a DC 11 Dexterity saving throw. A target takes 7 (2d6) fire damage on a failed save, or half as much on a successful save. The slug regains 7 (2d6) hit points.
Falling Slam. While the slug is climbing a ceiling or wall, it can use its reaction to fall and attack a creature that is moving below it with its Slam attack. If it falls at least 10 feet, the target takes an additional 3 (1d6) bludgeoning damage on a hit.
Upward Flame. While the slug is on the ground, it can use its reaction to blast a gout of fire directly above it. Any creature no more than 5 feet above the slug must make a DC 11 Dexterity saving throw. If the creature is falling onto the slug directly, it automatically fails this saving throw. On a failed save, the target takes 7 (2d6) fire damage and is knocked prone into an adjacent space. On a success, the target takes half damage and continues its movement as normal.
From a distance, a torch slug is indistinguishable from a pile of tar, magma, or black dirt that is visibly burning. This magical fire never consumes it and burns eternally. A torch slug feeds on heat, and as such is found almost exclusively in extremely hot environments such as in Subrosia, or inside active volcanoes. A simple creature, it is normally quite docile. A torch slug defends itself by blasting fiery heatwaves from its body; it only seeks to attack other beings when they are the single available source of heat.
