Vorstclaw

Siege Monster. The vorstclaw deals double damage to objects and structures.

Multiattack. The vorstclaw can use its Frightful Presence. It then makes two claw attacks.

Claw. Melee Weapon Attack: +10 to hit, reach 10 ft., one target. Hit: 13 (2d6 + 6) slashing damage.

Frightful Presence. Each creature of the vorstclaw's choice within 120 feet of it and aware of it must succeed on a DC 14 Wisdom saving throw or become frightened for 1 minute. A creature can repeat the saving throw at the end of each of its turns, with disadvantage if the tarrasque is within line of sight, ending the effect on itself on a success. If a creature's saving throw is successful or the effect ends for it, the creature is immune to the vorstclaw's Frightful Presence for the next 24 hours.
