  • Cloud of Carrion. The Tyrannosaurus king is surrounded by a cloud of buzzing insects and the ripe stench of rotting carcasses. All creatures that begin their turn within 15 feet of the Tyrannosaurus king must succeed at a DC 15 Constitution saving throw or gain the poisoned condition until they begin their turn more than 15 feet from the Tyrannosaurus king. A creature that saves against this effect is immune to it for 24 hours.
  • Innate Spellcasting. The Tyrannosaurus king’s innate spellcasting ability is Wisdom (spell save DC 14, +6 to hit with spell attacks). It can cast the following spells, requiring no material components:
  • Magic Resistance. The Triceratops king has advantage on saving throws against spells and other magical effects.
  • Magic Weapons. The Triceratops king’s weapon attacks are magical.


  • Multiattack. The Tyrannosaurus king makes one Bite attack and one Tail attack. The Tyrannosaurus king may substitute a swallow attack for its bite attack. It can’t make both attacks against the same target.
  • Bite. Melee Weapon Attack: +12 to hit, reach 5 ft., one target. Hit: 47 (6d12 + 8) piercing damage.
  • Swallow. The Tyrannosaurus king makes a Bite attack, and if it hits, the creature must succeed at a DC 18 Dexterity saving throw or be swallowed if the creature is Large sized or smaller. While swallowed, the creature is blind and restrained, it has total cover against attacks and other effects that originate from outside the Tyrannosaurus king and it takes 39 (6d12) acid damage at the start of the Tyrannosaurus king’s turn. The Tyrannosaurus king can have only two Large-sized creatures, four Medium-sized creatures, or six Small-sized creatures swallowed at one time. If the Tyrannosaurus king takes 50 damage or more on a single turn from a creature inside it, the Tyrannosaurus king must succeed on a DC 18 Constitution saving throw at the end of that turn or regurgitate all swallowed creatures, which fall prone in a space within 10 feet of the Tyrannosaurus king. If the Tyrannosaurus king dies, all swallowed creatures are no longer restrained by it and can escape from the corpse using 15 feet of movement, exiting prone.
  • Tail. Melee Weapon Attack: +12 to hit, reach 10 ft., one target. Hit: 24 (3d10 + 8) bludgeoning damage.


The Tyrannosaurus king can take three legendary actions, choosing from the options below. Only one legendary action can be used at a time and only at the end of another creature’s turn. The Tyrannosaurus king regains spent legendary actions at the start of its turn.

  • Rampage. The Tyrannosaurus king makes a Bite and a Tail attack.
  • Gobble (costs 2 actions). The Tyrannosaurus king makes two swallow actions.
  • Spit (costs 2 actions). The Tyrannosaurus king spits up to two creatures it has swallowed at up to two targets. This is a ranged weapon attack made at + 4 to hit, with a range of 20/40 feet, and inflicts 27 (5d10) bludgeoning damage on the creature hit and the creature spit out. Both the creature hit and the one spit out must succeed at a DC 20 Strength saving throw or become prone.


Dinosaur kings look like a normal member of the species with which they have bonded, albeit larger and far more intelligent. They are not truly made of flesh and blood, but ephemeral spirit stuff that behaves much the same way. Solitary like the creature’s whose form they have stolen, Tyrannosaurus dinosaur kings do not mate with their physical brethren nor do they associate with others of their kind. Instead, they draw to themselves a cadre of loyal raptors and other smaller predators who serve as a sort of court. While this court shows great loyalty to its king, the Tyrannosaurus king does not share that feeling and happily eats a follower if it pleases them.
