Geryon

Geryon is a three-bodied ruler and warrior whose distant red cattle are guarded by Orthrus and a loyal herdsman. His joined forms allow several weapons, viewpoints, and voices to operate as one will. Geryon treats theft as invasion and arrives prepared to recover property through overwhelming force, but he is capable of formal challenge, ransom, and proof of ownership.

Three Bodies, One Aim: Geryon makes three 3d10+5 weapon attacks, no more than two against the same target. Joined Advance: if all three bodies attack different targets, each target that is hit makes a Tough save or is moved 15 ft as the locked shields divide the battlefield. A successful save prevents the movement but does not undo the attack damage.

Challenge Recognized: a formal single-combat challenge accepted by Geryon prevents attacks against anyone else until the challenger withdraws or an ally interferes. Separating the three shields lowers DR by 2.
