Conjure Bone Chimera

You call upon dark necromantic powers to fuse the bones of at least two creatures into a singular, monstrous amalgamation—a Chimera of bone. The bones must be compatible in size and structure (DM’s discretion). The resulting creature is a mindless, soulless undead of bone and decaying flesh, bound to obey your commands. It retains features from each creature used, such as a dragon’s head, a hydra’s many limbs, or an ogre’s massive size. The Chimera exists for 1 year or until destroyed. Once the duration ends, the creature collapses into a pile of decaying bones. If the caster is killed before the duration is over, The Chimera will attack indiscriminately until destroyed or the duration ends.

Feasibility: The bones of creatures must be of a size and physiology that the DM deems compatible. (e.g. A Dragon’s head combined with a squirrel body is not viable, but a Hydra body with Dragon heads and ogre legs could work.)

Stats & Abilities:

• Challenge Rating (CR): The Chimera’s CR is the average of the CRs of the creatures used (multiplied by 2, rounded down).
• Hit Points: Average the hit points of all creatures used, then multiply by 1.5.
• Armor Class: The Chimera’s AC is the highest AC of the creatures used.
• Speed: The Chimera’s speed is the average of the combined movement speeds of all creatures used (rounded down).
• Attacks: The Chimera can make one or more attacks based on the creatures used (e.g., Dragon’s bite, Hydra’s claws, Ogre’s fists, multi-attack cannot exceed 5 attack actions).
• Regeneration: If one of the creatures had a regeneration ability (e.g., Hydra or Troll), the Chimera gains that ability, provided it has at least 1 hit point.

Special Features:

• Each creature contributes one special ability or feature to the Chimera (e.g., a Dragon’s fire breath, a Hydra’s multi-headed attacks, or a Troll’s regeneration). The DM determines which features apply based on the creatures involved.
• The created amalgamation is always immune to necrotic and poison damage, and vulnerable to radiant damage
• If One creature had legendary resistances, the Chimera inherits them.
