They appear when player has more than 25% Enlightenment and are aggressive toward player above 85%.
When approached, they will ball up and shoot in the player's direction. This can be avoided by moving out of the way. Their attacks deal no damage, and will instead increase Enlightenment by 10 and slow down the player for a few seconds. If the player is hit by too many Gestalt in a row, they will fall asleep for 6 seconds.
