found a bug:

as a hunter, if you initiate combat with a mob in the underground area, pull them back to the entrance and wait for them to get close, you can exit and keep attacking an invisible mob. the arrows glitch out a bit and stay in the air as if trying to hit something invisible then when you re-enter the underground, all the built up arrows will stream towards the mob and deal the appropriate amount of damage based on the number of projectiles.
