Keen Sight.

The nothic has advantage on Wisdom (Perception) checks that rely on sight.

Actions

Multiattack.

The nothic makes two claw attacks.

Claw.

Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 6 (1d6 + 3) slashing damage.

Mind Blast (Recharge 5–6).

The nothic magically emits psychic energy in a 30-foot cone. Each creature in that area must succeed on a DC 12 Intelligence saving throw or take 10 (2d8 + 1) psychic damage and have the stunned condition until the end of its next turn.

Weird Insight.

The nothic targets one creature it can see within 30 feet of it. The target must contest its Charisma (Deception) check against the nothic's Wisdom (Insight) check. If the nothic wins, it magically learns one fact or secret about the target. The target automatically wins if it is immune to being charmed.
