Ok, the new RJ/JK has had very confusing complaints about being "almost impossible" and "much easier"
It is extremely hard to find out which it is for me. Why? It's not because im like most of you and just walk through it with tier 4 / 5 gear (which i have with my wolver / calibur tier 4 set)
It's because i go back there with tier 2 gear and find it almost impossible regardless of the huge number comments saying that "Jelly King is more of a true tier 2 boss now" .... Remember: I am NOT using tier 3 gear so no fang of vogs / fausts / skolvers / whatevers when i did him.
So with the new mechanics:
1. There are polyps. these polyps spawn a lot of minis, and these minis heal the jelly king.
2. Jelly king does not spawn minis.
3. Jelly king bounces and damage anything that touches him.
4. The jelly king's normal attack now does a forward slide like normal cubes.
5. The jelly king is now weak to shadow and resistant to piercing with yesterday's update.
As far as tactics go: its kill polyps - kill jk - kill polyps - kill jk accoridng to the "tier 2 new jk is easier" comments. The issue is that doing these tests without 4* or 5* gear shows that the polyps starting in his crown-less phase where he will berserk will respawn quicker than they can even be put down. Remember, I am also soloing. Before I could solo the jelly king with ease and now i cannot.
What I have found is that the polyps have more health compared to normal polyps. It's difficult to kill them since the minis they spawn will be right in your face as well. When i was in full 3* dusker / nightblade (with a plate shield i had a 4* plate shield through all of this but i dont think this would make a huge difference with the true problem) the reach of the nightblade was so small for the jelly king himself that it was hard to avoic being bounced back. Obviously, you could not execute more than one attack since I would not understand how you wouldn't end up being knocked back due to No. 3 stated above. Because of this, i dont think any sword but calibur charge attack would be worth it on the jelly king (remember: this is not a tier 3 gear test, fang of vog is 5*) since you CAN get the 3-hit charge attack to work even with his new bouncing if you touch him.
So, that's that for swords. I also went down there with a shadowtech alchemer mk II and gunslinger gear to see how that would play out, since i read comments stating that it was gunnable and possibly even easier to gun him now. The issue is that i could not kill polyps fast enough like the nightblade, they would respawn too quick. when i poisoned him, he would very soon go berserk and that poison would ware off. if he was even close to any minis before i got that next vial off he would heal a ton, usually repeating his berserks.
So, to sum up that, am I maybe doing something wrong? With 3* gear from what i see the jelly king is not killable due to being unable to put down polyps fast enough and ridiculous healing when you ran out of poison vials you are basically done.
Is this new jelly king truly tier 2 or has everyone been killing him with tier 4/5 easily and then just believing that its doable in 3*? is there some magic that occurs when you aren't soloing (3 or 4 people) with this new jelly king? If you notice i am doing something wrong and you can (from the perspective of someone in 3* NOT 4* or 5*) tell me what it is, that would be awesome thanks!
I don't think you should kill the polyps if you're soloing. If you've got a full group of 4 then it's probably worth having one person go around killing them, but for any smaller groups I'd say just concentrate on RJ.
Your best option is probably to kite the minis around (there's much fewer than there used to be) and dive in on the big guy with charge attacks. The nightblade line charge attack is very useful here because of its long reach with the explosions, and obvious bonus for shadow damage with the latest update.
It helps if you've done a lot of brandish kite'n'charge soloing on the final wave of arenas with the piles of mechaknights so you know just how far away you should be to release the charge attack. It's obviously very important to get the range right to avoid the new head-butt.
