SPECIAL TRAITS

  • Legendary Resistance (3/Day). If an undead tarrasque fails a saving throw, it can choose to succeed instead. (All uses of this trait refresh when the tarrasque dies.)
  • Magic Resistance. The tarrasque has advantage on saving throws against spells and other magical effects.
  • Reflective Carapace. Any time the tarrasque is targeted by a magic missile spell, a line spell, or a spell that requires a ranged attack roll, roll a d6. On a 1 to 5, the tarrasque is unaffected. On a 6, the tarrasque is unaffected, and the effect is reflected back at the caster as though it originated from the tarrasque, turning the caster into the target.
  • Siege Monster. The tarrasque deals double damage to objects and structures.
  • Turn Immunity. The undead tarrasque is immune to any effect that turns undead.
  • Create Wraith. Any creature killed by the tarrasque rises as an uncontrolled wraith at the start of the creature’s next turn.

ACTIONS

  • Multiattack. The tarrasque can use its Frightful Presence. It then makes five attacks: one with its bite, two with its claws, one with its horns, and one with its tail. It can use its Swallow instead of its bite, and can use Hurl Debris instead of one or both of its claw attacks.
  • Bite. Melee Weapon Attack: +19 to hit, reach 10 ft., one target. Hit: 36 (4d12 + 10) piercing damage. If the target is a creature, it is grappled (escape DC 20). Until this grapple ends, the target is restrained, and the tarrasque can’t bite another target.
