Epic Boon of Crushing Depths

Your connection to Elemental Water enhances your Fathomless abilities, allowing you to summon more tentacles at once.

When you activate your Tentacle of the Deeps feature, you can use one of the options below:

• When you make a melee spell attack with your spectral tentacle, you can make a second attack against a target within 10 feet of the tentacle. On a hit, the target takes 2d8 cold damage, and its speed is reduced by 10 feet until the start of your next turn.
• Instead of making a melee spell attack, you can choose to consume your spectral tentacle to drag a target partway into the Elemental Plane of Water. Choose a creature within 10 feet of your spectral tentacle that is Huge or smaller. The target must succeed on a Strength saving throw against your Spellcasting DC or take 2d8 bludgeoning damage, 2d8 cold damage, and be restrained for 1 minute. A target that starts its turn restrained by this effect takes an additional 2d8 bludgeoning and 2d8 cold damage at the start of each of its turns and can repeat the saving throw at the end of its turn, ending the effect on a success. A creature that succeeds on the initial save takes half the damage and isn't restrained.
• Instead of making a melee spell attack, you can choose to consume your spectral tentacle to manifest an eruption of tentacles that pulls in all nearby creatures. Each creature within 15 feet of your spectral tentacle must succeed on a Strength saving throw against your Spellcasting DC or take 2d8 bludgeoning damage, 2d8 cold damage, and be pulled 15 feet into the space the tentacle occupies, or the nearest available space. Each of those creatures' speeds are reduced by 10 feet until the start of your next turn. A creature that succeeds its save takes half the damage, isn't pulled, and doesn't have its speed reduced.
