Barnos Indarna, Kyuss Knight

Gifts of Kyuss. Barnos Indarna’s eyeworms are longer and more potent than other Kyuss Knights, and his Mind Siphon is stronger.

Living Wounds. Kyuss Knights inflict horrifying wounds that open and close on their own, like tiny mouths suddenly brought to horrible life. Anyone a Kyuss Knight damages with a weapon attack suffers disadvantage on attack rolls and saving throws until their wounds are dressed with a DC 16 Medicine check or they receive any magical healing. Effects which cure disease or curses also end Living Wounds. This DC is Wisdom based.

Mind Siphon. A Kyuss Knight heals 8 hit points each time it deals psychic damage to another creature.

Multiattack.  Barnos Indarna uses Visions of the Worm, then makes two longsword attacks and two eyeworm bites.

Dagger. Melee Weapon Attack: +10 to hit, reach 5 ft., one target. Hit: 8 (1d4 + 5) piercing damage plus 7 (2d6) necrotic plus Living Wounds.

Eyeworm Bite. Melee Weapon Attack: +10 to hit, reach 15 ft., one target. Hit: 7 (1d4 + 5) piercing damage plus 9 (2d8) psychic damage plus Living Wounds.

Visions of the Worm. Barnos Indarna’s shadow stretches out from him to a distance of 60 feet. If it touches another creature’s shadow, they must make a DC 18 Wisdom saving throw or be stunned for one round, overcome with visions of the utter horror and hopelessness of the as yet unborn Age of Worms.

Worm Healing. A Kyuss Knight is healed by the power trapped within the writing worms of Kyuss. As a reaction, it can consume an adjacent wormswarm to remove all ongoing conditions and fully restore its hit points. The wormswarm is completely destroyed, but makes no move to defend itself from this consumption.

Barnos Indarna can take 3 legendary actions, choosing from one of the options below. Only one legendary action option can be used at a time, and only at the end of another creature’s turn. He regains spent legendary actions at the start of its turn.

Attack. Barnos Indarna makes an Eyeworm Bite attack.

Sicken (2 actions). Barnos Indarna’s shadow stretches out, touching one creature of his choice 60 feet. The target must make a DC 18 Constitution saving throw or become sickened, suffering disadvantage on attack rolls and ability checks. It can make a new saving throw at the end of each of its turns, ending the effect on a success.

Worm Healing (2 Actions). Nezzarin takes the Worm Healing reaction, even if it has already used a reaction this turn.
