Spectator

The Spetator is a rare enemy found in the Revenge of Cthulhu event. When one spawns, another one can't spawn unless the first one is defeated. It attacks by blasting one big laser from it's large eye, then using small lasers from it's tentacle eyes every 1-2 seconds.

This was based off of the Beholder from Dungeons and Dragons.
