Recovery Debuff Pattern

• This pattern start at the beginning. He target one member and shoot a non-lethal laser. This member will have a purple mark on them.
• This person will not be able to recover HP through potions or equipment.

• If the person with the mark die, he will fire all his remaining missiles. This pattern is quite long and almost impossible to survive without invisibility. If you die, don't use coin right the way, wait until his missiles hit zero then revive.

Cross Pattern

• During this pattern, you will see one red area and one green area. The safe zone is where those 2 lines meet (very similar to Black Purgatory pattern)

Land Mine Pattern

• He summons turrets and land mines all around. Dodge by standing away, then stay inside the green safe zone.

Chessboard Pattern

• He alternately fires missiles into the squares. Pretty simple, just avoid the red tiles.

Top & Bottom Pattern

• He divides the map into top and bottom. You will see one side lighted up with an arrow indicating the missile direction. Here simply run clockwise or counter-clockwise depending on the direction.
• In the example GIF below, the arrow is at the bottom going >>>, so you run from the top <<< then go downward (aka counter-clockwise).

Berserk Pattern

• You will see a "Warning" purple message on the screen. He hen jump to the 12 o'clock and start firing missiles. There will be various missile firing patterns here. At any point, if he runs out of missiles, the pattern will stop.
• The first patterns is the sweep. He do a sweep left to right and right to left. Pretty easy to avoid, just stay on the top (or you can jump too).

• Another variant is you will see a tracking cross on the floor. Simply move that cross out of the way so it won't target you.

• During this pattern, you will see a small health bar underneath him. Empty this will give you a small groggy.
