You cant say 17,5k trash after 15 min^^ I clear way faster than this and I aint getting no 17,5k on my succ hash^^ Overclearing in marni realm, having to go down to the bottom rotation and up.
Sure he can, he gets 4453 trash in 15minutes *4 = 17.8k/hour. Crypt is a very consistent spot because it doesn't have buff / boss mechanics like elvia / gyfin which fluctuates the trash per hour, if you make 4453 trash in 15minutes chances are he's going to make 17.4k trash in the next 45minutes.
