Tyrannosaurus Rex, Variant (5e Creature)
From D&D Wiki
Gargantuan beast, unaligned
Multiattack. The tyrannosaurus makes three attacks: one with its bite, one with its tail, and one with its kick. It must make each attack against a different target.
Bite. Melee Weapon Attack: +13 to hit, reach 10 ft., one target. Hit: 35 (4d12 + 9) piercing damage. If the target is a Medium or smaller creature, it is grappled (escape DC 19). Until this grapple ends, the target is restrained, and the tyrannosaurus can't bite another target.
Tail. Melee Weapon Attack: +13 to hit, reach 15 ft., one target. Hit: 22 (3d8 + 9) bludgeoning damage, and if the target is a creature, it must succeed on a DC 19 Strength saving throw or be knocked prone.
Kick. Melee Weapon Attack: +13 to hit, reach 5 ft., one target. Hit: 19 (3d6 + 9) bludgeoning damage. If the target is a prone creature, it takes an additional 7 (2d6) bludgeoning damage.
This apex predator is much more of an ambush hunter, but it is a hunter nonetheless. Relying on its powerful jaws to both crush and shake senseless prey it is able to debilitate prey to the point where they simply cannot fight back. Lone adventurers are a very easy magical meal.
