I tested jelly king new fight (if we can say new) and I have found many problem with it. With a 4 man group fully geared in 3* gear level 10 with no trinket and very good against slime equipement, we had a hard time killing him. We all had to resurect 4-5 times in order to get a kill.
I'd say the main problem is the amount of health the boss regain via absorbtion and the rate small jelly spawn. We had a constant poisoning on the boss in order to keep the healing low, but even then in smal period of unpoisoning. I did 2 man it in 5* star gear evel 10 with fang of vog, and thing really overpowered for this fight but that is exactly the problem. I should be able to do this in a much easier way then right now in 3* gear (considering it is tier 2)
the healing is in my opinion too high (about 57 health per add). Don't make less small jelly spawn since it is the whole essence of this boss. Just make them heal him less often or for less damage.
Agree with the rapid regain of health.
And the animation of the JK moving was a bit slow causing, sometimes, me to it from a distance, like there was a invisible barrier between me and JK...
i used the Dread Venom+Poison Vials+Grand Faust and the Virulusk Combo with the BTS, but i got overpowered and revived 6 times before i quit.
