Planar Bestiary
The offspring of fiendish parents, or fiendish and mortal parents, is seldom wholesome. Cambions (humanoids with some devilish features and abilities) are one example. Reymcubi are another.
The reymcubus's true form is a gruesome, shadow-dripping fiend of spikes and way too many teeth. Despising themself as much as they despise others, a reymcubus often uses magic to take on a pleasing form, possibly even one of exceptional attractiveness. However, their hunger often wins out over keeping themself disguised.
Many reymcubi begin life already pledged to a demon or devil authority that expects terrible things of them. Such reymcubi are often only too happy to comply. But such service is tested if a reymcubus is ordered to work with a cambion. Reymcubi hate cambions more than all others.
Motive: Serve evil
Environment: Almost anywhere in the multiverse fiends roam, alone (often in a pleasing shape) or with other fiendish allies
Health: 33
Damage Inflicted: Moderate wound (7 points)
Armor: 2
Movement: Short
Modifications: Speed defense as level 6 due to large size; perception as level 9
Combat: The reymcubus attacks twice each round with their bite. If they successfully bite the same target twice on their turn, the target is stuck to the reymcubus's body spikes until they can escape with a successful Might task. All a stuck target's physical tasks are hindered. Victims automatically take damage from the impaling spikes each round they remain stuck.
A reymcubus can unleash a hellish scream every few rounds, targeting a creature within long range. A target that fails a Might defense task takes 10 points of damage from the infernally loud sound and is stunned on their next turn, unable to act.
Whenever they wish, a reymcubus can change their shape, taking the form of a common humanoid species. Their statistics are the same in each form (except they can't bite). Any equipment they are wearing or carrying isn't transformed.
The reymcubus regains 2 points of health each round unless they took damage from radiant energy last round.
A reymcubus is vulnerable to radiant attacks; every time they take damage from radiant energy, they take 3 additional points of damage.
Interaction: While shapechanged into a humanoid form, the reymcubus pretends to be normal, possibly even living as a member of the community. But that's only so they can pursue unspeakable acts when no one is aware. If discovered, the reymcubus reveals their true nature and attacks without mercy.
Use: A wanderer appears, begging for food and shelter in return for helping with chores. The chores are completed in a slipshod fashion, but that's overshadowed by a series of terrible events that begin befalling the larger community.
Loot: A reymcubus may carry a few useful magical cyphers, such as a shirt of wings and an X-ray viewer ring.
GM Intrusion: A character within immediate range of the reymcubus is drenched in a wave of shadow moving almost like liquid, inflicting 7 points of Speed damage (ignores Armor) from necrotic energy and blinding them in residual darkness until their next turn.
GM Intrusion: The reymcubus disappears into shadow, reappearing at any point within long range that is dim, shadowed, or dark.
