Behavior
It has two main attacks. When it spawns it will start with the first attack. The 1st attack has it flying around (left and right included) above the player and slowly shoot lasers. The lower his health gets, he'll use his attack more frequent. He will use his attack for about 10-15 seconds, then move one to the second attack. Times to shoot a laser for 1st attack: His second attack is when he spins around and moves around randomly, hovering above the ground by 10 blocks, and summons 5-7 Meteor Vessel. About a second later after releasing all the Vessels, He returns to the first attack.
