Doubletyped. For the purposes of features, spells, and traits, Caliban counts as both a beast and humanoid .

Keen Senses. Caliban has advantage on Wisdom (Perception) checks that rely on sight, smell, and sound.

Pounce. If Caliban moves at least 20 feet straight toward a creature and then hits it with a claw attack on the same turn, the target must succeed on a DC 12 Strength saving throw or be knocked prone . If the target is prone, Caliban can make one bite attack against it as a bonus action.

Relentless Endurance (1/long rest). When Caliban is reduced to 0 hit points but not killed outright, he can drop to 1 hit point instead.

Running Leap. With a 10-foot running start, Caliban can long jump up to 40 feet.

Stench. Any creature that starts its turn within 10 feet of Caliban must succeed on a DC 13 Constitution saving throw or be poisoned until the start of its next turn. On a successful saving throw, the creature is immune to Caliban’s stench for 24 hours.


Multiattack. Caliban attacks once with its bite and twice with its claws, or twice with thrown rocks.

“You taught me language, and my profit on’t Is, I know how to curse. The red plague rid you For learning me your language!”

From Shakespeare’s play The Tempest, the creature known as Caliban is a half-man half-monster born of the witch Sycorax and abandoned on a remote island along with the air spirit, Ariel, who Sycorax imprisoned in a pine tree. Some time after Sycorax’s death Prospero the magician ‒ the former Duke of Milan ‒ and his daughter Miranda were shipwrecked on the island, and using his powerful magic Prospero enslaved Caliban because the first time they met the beastman, Caliban tried to rape Miranda.

The resentful Caliban rejected Prospero and worshipped another shipwrecked traveler, a servant named Stephano. In the end, however he realized the servant was not the magician’s equal, and accepted Prospero as his master.

“That, if I then had waked after long sleep, will make me sleep again and then in dreaming, the clouds me thought would open and show riches ready to drop upon me, that when I waked I cried to dream again.”
