Battletitan

Eldritch Turret. Ranged Spell Attack: +10 to hit, range 300 ft., one target. Hit: 18 (4d8) force damage, and if the target is a creature, it is knocked prone.

Incinerating Beam (Recharge 5-6). The battletitan fires a beam of light in a 150-foot line that is 10 feet wide. Each creature in the line must make a DC 17 Dexterity saving throw, taking 33 (6d10) radiant damage on a failed save, or half as much damage on a successful one. A creature reduced to 0 hit points by this beam is disintegrated, leaving behind anything it was wearing or carrying.

Multiattack. The tyrannosaurus makes three attacks: two with its claws one with its bite or tail

Bite. Melee Weapon Attack: +12 to hit, reach 10 ft., one target. Hit: 34 (4d12 + 8) 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 battletitan can't bite another target.

Claws. Melee Weapon Attack: +12 to hit, reach 10 ft., one target. Hit: 17 (2d8 + 8) slashing damage.

Tail. Melee Weapon Attack: +12 to hit, reach 10 ft., one target. Hit: 19 (2d10+8) bludgeoning damage.

Swallow. The battletitan makes one bite attack against a Medium size or smaller target it is grappling. If the attack hits, the target takes normal bite damage and is swallowed. The swallowed target is no longer grappled, but is blinded and restrained, has total cover against attacks and other effects outside the battletitan, and takes 14 (4d6) acid damage at the start of each of the battletitan’s turns. The battletitan can have only one medium-sized, two small-sized, or eight tiny-sized targets swallowed at a time. If the battletitan dies, a swallowed creature is no longer restrained, and it can escape from the corpse by using its action to make a successful DC 14 Strength saving throw. When a creature escapes from the corpse, it is prone.
