I took my first run through the Jelly King stratum today, solo, and I made it to the king himself without any deaths, but I couldn't down the big guy himself (I took two revives and called it a day on my third death). What I want to know is am I doing the fight itself wrong, or do I just not have good enough gear for it?
What I'm currently wearing:
3* Tempered Calibur L10
3* Cryotech Alchemer Mk II L9
3* Dusker Cap L7
3* Dusker Coat L5
3* Horned Owlite Shield (UV Elemental Medium) L5
