Legendary Resistance (3/Day). If the Warden fails a saving throw, it can choose to succeed instead.
Abyssal Guardian. The Warden is immune to the effects of depth pressure, strong currents, and magical water-altering effects. While in underwater combat, it does not suffer disadvantages with melee attacks.
Tidal Stride. Difficult terrain caused by water does not affect the Warden, and it can walk on the ocean floor as if on land.
Multiattack. The Abyssal Warden makes three attacks: one with Crushing Slam, one with Abyssal Strike, and one with Tidal Surge.
Crushing Slam. Melee Weapon Attack: +14 to hit, reach 10 ft., one target. Hit: (5d10 + 8) bludgeoning damage. The target must make a DC 20 Strength saving throw or be prone. If underwater, the target is flung 30 feet away.
Abyssal Strike. Ranged Weapon Attack: +12 to hit, range 60 ft., one target. Hit: (4d8 + 8) force damage. The target must succeed on a DC 18 Strength saving throw or be pulled 20 feet closer.
Tidal Surge (Recharge 5-6). The Warden unleashes a surge of water in a 30-foot radius. Each creature in the area must make a DC 21 Strength saving throw or take (8d8) bludgeoning damage and be restrained in swirling currents until the end of their next turn. Creatures immune to being grappled are unaffected.
The Abyssal Warden can take 3 legendary actions, choosing from the options below. Only one legendary action option can be used at a time and only at the end of another creature’s turn.
-
Looming Presence (Costs 1 Action). The Warden emits an aura of dread. Each creature within 30 feet must make a DC 18 Wisdom saving throw or be frightened until the end of its next turn.
-
Seabed Quake (Costs 2 Actions). The Warden stomps the ocean floor, causing a shockwave. All creatures within 20 feet must succeed on a DC 21 Dexterity saving throw or take (4d10) bludgeoning damage and be knocked prone.
-
Regenerate (Costs 2 Actions). The Warden absorbs abyssal energy, regaining 40 HP.
Description
Phase Transition – The Trial of the Abyss (40% HP)

-
3,000 GP in Sunken Relics.
Lair and Lair Actions
As you drift forward, the ruins pulse with cold, green light, illuminating the seabed beneath you. The broken bones of long-dead warriors shift slightly, stirred by an unseen force.
Then, the silence is shattered.
With a deep, grinding groan, the enormous figure before you rises from its slumber—a towering construct of fused coral and jagged bone, its form held together by strands of glowing abyssal energy. Its eyes ignite like twin ghostly lanterns, scanning you with eerie intelligence
On Initiative Count 20, the Warden can use a lair action:
-
Geyser Blast: A jet of boiling water erupts for a DC 20 Dexterity save or (6d10) fire damage.
-
Dark Tide: Water darkens, heavily obscuring a 30-foot radius until next round.
-
Riptide Pull: A current yanks creatures toward the Warden, DC 18 Strength save or be pulled 15 feet.
