Urkalithor

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

Weakening Energy Cone. The urkalithor's central eye emits an invisible, magical 90-foot cone of weakening energy. At the start of each of its turns, the urkalithor decides which way the cone faces and whether the cone is active. The urkalithor is not affected by its own energy cone.

Any creature in the cone has disadvantage on Strength-based attack rolls, Strength checks, and Strength saving throws.

Multiattack. The urkalithor makes 3 attacks: one with its bite and two with its tentacles.

Bite. Melee Weapon Attack: +10 to hit, reach 5 ft., one target. Hit: 22 (3d10 + 6) piercing damage.

Tentacle. Melee Weapon Attack: +10 to hit, reach 10 ft., one target. Hit: 16 (3d6 + 6) bludgeoning damage plus 5 (2d4) lighting damage and target creature must make a DC 16 Constitution saving throw or become stunned until the start of the urkalithor's next turn.

Deflect Projectile. The urkalithor uses its tentacles to partially deflect a projectile, reducing its damage by half.
