Bite. Melee Weapon Attack: +1 to hit, Reach 5ft, One target. Hit: 2 (1D6-1) Piercing Damage.   Eye Rays. The spectator shoots up to two of the following magical eye rays at one or two creatures it can see within 90 feet of it. It can use each ray only once on a turn.  

1. Confusion Ray. The target must succeed on a DC 13 Wisdom saving throw, or it can't take reactions until the end of its next turn. On its turn, the target can't move, and it uses its action to make a melee or ranged attack against a randomly determined creature within range. If the target can't attack, it does nothing on its turn.

3. Fear Ray. The target must succeed on a DC 13 Wisdom saving throw or be frightened for 1 minute. The target can repeat the saving at the end of each of its turns, with disadvantage if the spectator is visible to the target, ending the effect on itself on a success.
4. Wounding Ray. The target must make a DC 13 Constitution saving throw, taking 16 (3D10) Necrotic damage on a failed save, or half as much damage on a successful one.

Reactions

Spell Reflection. If the spectator makes a successful saving throw against a spell, or a spell attack misses it, the spectator can choose another creature (including the spellcaster) it can see within 30 feet of it. The spell targets the chosen creature instead of the spectator. If the spell forced a saving throw, the chosen creature makes its own save. If the spell was an attack, the attack roll is rerolled against the chosen creature.
