- Don't waste your time. The latest version of the JK is much easier to take down then previous incarnations. Just concentrate on damaging the King and keeping him under a status effect (curse, poison, fire, shock) and it will go really quick.
This.
Really, Jelly King is just going to keep making Polyps and, from my experience, they take quite a bit to kill. You and your party(assuming you go with parties.) can out damage his healing rates fairly easy. If the healing is a problem, then look into vials as death mentioned and/or get yourself a status inflicting weapon like the status bombs or the status brandishes.
You could try out the starving method, but I feel you(and your group) can just out damage him more easily than taking out his healers.

I do like to do Calibur charges to clear out the little stuff while hitting the JK or if you are in a group a freeze bomb is handy to lock the small stuff (or any other bomb to kill off the small stuff).
