Hold Breath. The spinosaurus can hold its breath for 1 hour.
Multiattack. The spinosaurus makes three attacks: one with its bite, one with its claws, and one with its tail. It can't make its tail attack against the same target as its bite attack.
Bite. Melee Weapon Attack: +10 to hit, reach 5 ft., one target. Hit: 24 (3d10 + 7) piercing damage. If the target is a Medium or smaller creature, it is grappled (escape DC 17). Until this grapple ends, the target is restrained, and the spinosaurus can't bite another target.
Claw. Melee Weapon Attack: +10 to hit, reach 5 ft., one target. Hit: 16 (2d8 + 7) slashing damage.
Tail. Melee Weapon Attack: +10 to hit, reach 10 ft., one target. Hit: 26 (3d10 + 7) bludgeoning damage. If the target is a creature, it must succeed on a DC 18 Strength saving throw or be knocked prone.
Spinosaurus is a giant aquatic predator, almost as large as a tyrannosaurus rex, but shorter and longer. They possess a long crocodile-like head filled with teeth, short, stubby legs, and a massive sail. These predators live in deep rivers and wetlands filled with massive fish and spend most of their time in the water.
