Actions
Multiattack: Kaemon makes four attacks: one with his Bite, one with his Pincer, one with his Tentacle, and one with his Sting.
Bite: Melee Weapon Attack: +16 to hit, reach 10 ft., one target.
Hit: 25 (3d10 + 9) piercing damage. If the target is a Large or smaller creature, it is grappled (escape DC 23). Until this grapple ends, the target is restrained, and Kaemon cannot bite another target.
Pincer Claw: Melee Weapon Attack: +16 to hit, reach 15 ft., one target.
Hit: 22 (3d8 + 9) bludgeoning damage plus $9$ ($2\text{d}8$) slashing damage. If the target is a Huge or smaller creature, it is grappled (escape DC 23). Kaemon has two pincers, each of which can grapple one target.
Tentacle: Melee Weapon Attack: +16 to hit, reach 20 ft., one target.
Hit: 18 (2d8 + 9) bludgeoning damage. If the target is a creature, Kaemon pulls it up to 15 feet straight toward him, and it must succeed on a DC 23 Strength saving throw or be knocked prone.
Scorpion Sting: Melee Weapon Attack: +16 to hit, reach 15 ft., one target.
Hit: 20 (2d10 + 9) piercing damage plus 28 (8d6) poison damage, and the target must succeed on a DC 23 Constitution saving throw or be poisoned for 1 minute. While poisoned in this way, the creature takes 14 (4d6) poison damage at the start of each of its turns. The target can repeat the saving throw at the end of each of its turns, ending the effect on a success.
Death Roll (Recharge 5–6): Kaemon violently thrashes with a creature currently grappled in his jaws. The target takes 42 (6d10 + 9) bludgeoning damage, is knocked prone, and is stunned until the end of its next turn on a failed DC 23 Dexterity saving throw, or takes half as much damage and is not stunned on a success.
Innate Spellcasting
Kaemon's innate spellcasting ability is Charisma (spell save DC 21, +13 to hit with spell attacks). He can innately cast the following spells, requiring no material components:
At will: contagion, create or destroy water, dissonant whispers, ray of enfeeblement
3/day each: control water, enemies abound, synaptic static, blight
1/day each: dominate monster, feeblemind, tsunami
Tactical Synergies
Opening Gambit: Kaemon opens with synaptic static to muddle the minds of spellcasters and sap attack rolls before closing into melee.
Control & Isolation: While holding an enemy in his crush grip or bite, he casts enemies abound or dissonant whispers to force panicked allies to scatter or turn on each other in the brine.
Rot Infliction: Using contagion (Slimy Doom or Flesh Rot) in tandem with his Death Roll and Scorpion Sting guarantees target vulnerability and rapid action denial.
Legendary Actions
Kaemon 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. Kaemon regains spent legendary actions at the start of his turn.
Tentacle Sweep: Kaemon lashes out with an octopus tentacle at a target within 20 feet.
Venomous Strike (Costs 2 Actions): Kaemon makes one attack with his Scorpion Sting.
Crush (Costs 2 Actions): Kaemon constricts with his pincers. Each creature currently grappled by his pincers takes 22 (3d8 + 9) bludgeoning damage and must succeed on a DC 23 Constitution saving throw or lose its breath and be unable to speak or cast spells with verbal components until the start of Kaemon's next turn.
Abyssal Surge (Costs 3 Actions): Foul brine and necrotic muck erupt around Kaemon in a 20-foot radius. Each creature in that area must make a DC 23 Dexterity saving throw, taking 21 (6d6) necrotic damage and falling prone on a failure, or half as much on a success.
