"If you insist." Arkain sends up three more replicas when you destroy those three, he sends up four replicas. Now each time you back is turned to one of them  it attacks you with as many punches and side kicks as it can before the are dissipated. But you will start to notice something with each proceeding replica you dissipate. It takes steadily more effort to do it and each punch is having a stronger impact as if the gel is getting thicker with each one you dissipate.
