Alright so I've tried soloing Jelly King twice, even dropping up to 340ce on reviving.
I of course haven't done it yet.
Equipment:
Leviathan Blade Lv. 3: Medium Bonus to Fiend
Nightblade Lv. 3: Low Charge Time Reduction
Vile Striker Lv. 5: Medium Bonus to Undead
Mega Magnus Lv. 5: Medium Bonus to Gremlin
Ash Tail Cap Lv. 7: Low Shock Resist
Ash Tail Coat Lv. 5: Low Piercing Defense
Dark Thorn Shield Lv. 9: Low Damage Bonus
Wise Owlite Shield Lv. 1: Medium Shadow Defense
Maybe I just suck? Not sure, I would consider paying for training though xD
On a sidenote. I watched a few youtube videos and tried kiting other jellies to get them stuck then go at the boss. Just the vials and the Vile Striker charged wouldn't cut it. Even if I kept poison on.
Like title says tips are appreciated.
Thanks for your time,
Maerath
Well you're soloing it so its still going to be a bit tougher. What you want to do first is make sure you've got Poison, Fire, and Curse Vials, along with Health pills. Now the Curse vials are mainly for the end when the King starts to spin. But if you have 3 then using one earlier doesn't really hurt. Poison is a big one here that you want to make sure is always on the King. Add Fire to it to damage him then keep striking him and shield as he attacks.
Save your pills for when you're at half health or lower then run away and find time to use 2 of your health pills (unless 1 fills you up) that way you can run back in at full power.
Obviously the King is invincible when he starts going insane and spins like crazy. After a few times of seeing it you'll be able to estimate his position for when the attack ends at which point you'll want to hit him with Curse and Poison. There is a small interval here so it may be better to go with Curse first since it lasts quite a while. THen you can poison him and strike again.
Other tips are to make sure you're close to the King at all times (except when he's spinning) since you don't want your vials to hit the mini jellies and you still want to attack him. It also keeps you from being boxed off while a vial is in your hands which means you have to waste your vial. Kiting the jellies is a waste of time that I wouldn't bother with its really not that effective. I Imagine with your Ash Tail items and your Thorn Shield it shouldn't be too tough to beat Jelly King down.
