Amphibious. The hydroloth can breathe air and water.

Dashing Strike. If the hydroloth uses its action to Dash, it can use a bonus action to make one melee weapon attack or shove a creature.

Innate Spellcasting. The hydroloth’s innate spellcasting ability is Intelligence (spell save DC 16). It can innately cast the following spells:

At will: darkness, detect magic, dispel magic, invisibility (self only), water walk

3/day each: bloodlust, control water, fear, suggestion, terrifying visage

Magic Resistance. The hydroloth has advantage on saving throws against spells and other magical effects.

Magic Weapons. The hydroloth’s weapon attacks are magical.

Secure Memory. The hydroloth is immune to the waters of the River Styx as well as any effect that would steal or modify its memories or detect or read its thoughts.

Watery Advantage. While submerged in liquid, the hydroloth has advantage on attack rolls.

Actions

Multiattack. The hydroloth makes two melee attacks. In place of one of these attacks, it can cast one spell that takes 1 action to cast.

Claws. Melee Weapon Attack: +9 to hit, reach 1.5 m. Hit: 14 (2d8 + 5) slashing damage.

Bite. Melee Weapon Attack: +9 to hit, reach 1.5 m. Hit: 16 (2d10 + 5) piercing damage.

Steal Memory (1/long rest). The hydroloth targets one creature it can see within 18 meters of it. The target takes 4d6 psychic damage, and it must make a DC 16 Will saving throw. On a successful save, the target becomes immune to this hydroloth’s Steal Memory for 24 hours. On a failed save, the target loses all proficiencies, it can’t cast spells, it can’t understand language, and if its Intelligence and Charisma are higher than −3, they become −3. Each time the target finishes a long rest, it can repeat the saving throw, ending the effect on itself on a success. A greater restoration or remove curse spell cast on the target ends this effect early.

Teleport. The hydroloth magically teleports, along with any equipment it is wearing or carrying, up to 18 meters to an unoccupied space it can see.
