Awakened Brawn(Nyrith the Tidecaller)

Legendary Resistance (3/Day). If the dragon fails a saving throw, it can choose to succeed instead.

• Magic Resistance. Advantage on saving throws against spells and magical effects. •
• Oceanic Mind. Immune to effects that would magically alter emotions or force movement.
• Tidal Blood When struck by a melee attack, the attacker takes 2d8 cold damage as a burst of freezing seawater erupts from Brawn's scales. Crushing Depths (10 ft.) Enemies that start their turn within 10 feet of Brawn must succeed on a DC 19 Strength save or have their speed reduced by 15 feet until the start of their next turn. The pressure of the deep ocean weighs upon them.

Bite +13 to hit, reach 10 ft. 2d10 + 8 piercing + 2d8 cold Riptide Pull On hit, the target must succeed on a DC 19 Strength save or be pulled up to 15 feet directly toward Brawn.

Claw +13 to hit, reach 5 ft. 2d6 + 8 slashing Crushing Wave If both claws hit the same target on Brawn's turn, the target takes an additional 3d6 force damage and cannot take reactions until the start of its next turn.

Tidebreak (Recharge 4–6) Brawn slams his forelimbs into the ground, calling forth a surge of sapphire energy and spectral ocean water. 30-foot radius DC 20 Strength save 10d8 force + 4d8 cold (Half on success) Undertow Creatures that fail the save are knocked prone and pulled 15 feet toward the center of the effect.
