From D&D Wiki
Eye of Cthulhu
Huge aberration, lawful evil
Saving Throws Dex +5, Wis +6
Cthulhu’s Gaze If a creature starts its turn within 60 feet of the Eye of Cthulhu and the two of them can see each other, the Eye of Cthulhu can force the creature to make a DC 14 Wisdom saving throw or be incapacitated for 1 minute as it realizes the true nature of this being. A creature incapacitated this way can repeat the saving throw at the end of each of its turns, ending the effect on itself and becoming immune to the Eye of Cthulhu's gaze for 24 hours on a success.
Legendary Resistance (3/Day). If the Eye of Cthulhu fails a saving throw, it can choose to succeed instead.
Multiattack. The Eye of Cthulhu makes one bite attack and uses its Summon Servants.
Bite. Melee Weapon Attack: +3 to hit, reach 5 ft., one target. Hit: 10 (3d4 + 1) piercing damage.
Summon Servants. The Eye of Cthulhu summons 3 (1d4 + 1) servants of Cthulhu which are under its control.
The Eye of Cthulhu 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. The Eye of Cthulhu regains spent legendary actions at the start of its turn.
A massive eye with vein-like tendrils trailing behind it. A piece of Cthulhu ripped still-living from his body, the Eye wanders in search of its host body. The approach of the Eye of Cthulhu can be felt far in advance, as those in its path are plagued with a sense of being "watched".
