Planar Bestiary
Ghaths are servitor creatures constituted by other aberrations from the rude matter of the multiverse. A ghath instinctively serves whichever creature formed them. They operate as spies, messengers, soldiers, or, often enough, as part of a nightmare entourage.
A ghath may be built up from two or more corpses of any kind, from stone and soil, or even sometimes from still-living flora and fauna. In this latter case, the living tissue may squirm and cry out, asking for help (if they retain vocal cords) even as the ghath they have become the body for does unspeakable things. A ghath is almost but not quite an automaton. As with anything spawned in the execrable domain outside our own cosmos, definitions and delineations are approximate at best.
If ghaths are abandoned by their creator, they degrade and crumble within a few days. Some manage to persist by remaining in clusters hidden below ground, predating nearby creatures for new raw material to reinforce their own crumbling façades and new life force to keep their minds sharp.
If accompanying a more powerful aberration, ghaths are bold and aggressive, showing themselves and declaring their purpose to their foes. However, lone ghaths prefer to hunt from ambush, using their bodies formed from the environment as ideal camouflage from which to spray prey with a viscous fluid that stifles both movement and breath.
Motive: Hungers for flesh (to reinforce their body)
Environment: Anywhere in the multiverse, alone or in a group of two or three accompanying a more powerful aberration
Health: 12
Damage Inflicted: Moderate wound (4 points)
Movement: Short; short when flying
Modifications: Speed defense as level 2 due to large size; stealth as level 5
Combat: A ghath attacks twice each round with fists formed of their jumbled flesh. Each fist deals 2 points of damage plus 2 points of Speed damage (ignores Armor) from an acidic poison. If a ghath reduces a target to 0 health or Pool points, the target isn't dead but instead falls into a deathlike trance for about an hour, even if the victim is healed in some fashion before the hour elapses.
Every few rounds, a ghath can spray poisonous mucilage at a target within short range. On a failed Speed defense task, the target takes 3 points of Speed damage (ignores Armor) and can't take physical actions as the covering mucilage hardens into a clear shell (level 3). Each round a target can't break free, they take 3 more points of Speed damage (ignores Armor) from insinuating poison.
Interaction: Ghaths can pick up almost any standard language after just a few exchanges. They might use this gift to interrogate newly captured prey about the location of other potential targets (before incorporating the prey's flesh into themselves).
Use: A family living at the village edge is gone. But townsfolk whisper of seeing a horrible creature hunting the night. The creature supposedly contains recognizable features of each missing family member.
Ghaths within a cluster usually cooperate with each other. But if ghaths of two different genesis events discover each other, rival clusters can form. Such groups predate each other.
GM Intrusion: A character's successful melee attack triggers a defensive poison spray that inflicts 3 points of Speed damage (ignores Armor) to the character.
