Super-Heated Arctic Arthropods
Habitat: Arctic; Treasure: None
Full-grown remorhazes are single-minded ambush predators. They attempt to bite prey and trap it against their searing bodies, then swallow their meal whole. Remorhazes eat as much as they can, since they might go months without feeding.
Remorhazes are centipede-like terrors that burrow through snow and ice to ambush smaller creatures that trespass in their frozen territories.
Heat Aura. At the end of each of the remorhaz’s turns, each creature in a 5-foot Emanation originating from the remorhaz takes 16 (3d10) Fire damage.
Bite. Melee Attack Roll: +11, reach 10 ft. Hit: 18 (2d10 + 7) Piercing damage plus 14 (4d6) Fire damage. If the target is a Large or smaller creature, it has the Grappled condition (escape DC 17), and it has the Restrained condition until the grapple ends.
Swallow. Strength Saving Throw: DC 19, one Large or smaller creature Grappled by the remorhaz (it can have up to two creatures swallowed at a time). Failure:
The target is swallowed by the remorhaz, and the Grappled condition
ends. A swallowed creature has the Blinded and Restrained conditions, it
has Total Cover against attacks and other effects outside the remorhaz,
and it takes 10 (3d6) Acid damage plus 10 (3d6) Fire damage at the
start of each of the remorhaz’s turns.
If the remorhaz takes 30
damage or more on a single turn from a creature inside it, the remorhaz
must succeed on a DC 15 Constitution saving throw at the end of that
turn or regurgitate all swallowed creatures, each of which falls in a
space within 5 feet of the remorhaz and has the Prone condition. If the
remorhaz dies, any swallowed creature no longer has the Restrained
condition and can escape from the corpse by using 15 feet of movement,
exiting Prone.
