I'm currently using almost all 3* items. I'm trying to beat the Jelly King for the first time, so this is what I have when I do that run.
Chroma Helm 3* >UV Bonus to normal defense<
Chroma Suit 3*
Prismatech Alchemer MKII 3*
Shadow Alchemer 2*
Pepperbox 3*
Defender/Skelly Shield 2* (I switch between them depending on what Clockwork route I take)
There's a severe lack of decent armor/shield for Gunners, I already own the 3* Gunslinger helm and armor, but Chroma gives me Piercing defense and status resist against poison/fire.
Question; what armors should I consider getting in the future? And to that extent, what guns?
Fact-Jelly King is impossible with only guns.
I suggest you go swordie, like me but...
You'll want a grey Owlite shield, then eventually a crest of Almire.
In the end, the guns you will want are:
Biohazard
Callahan/Blitz Needle
Polaris/Argent Peacemaker
Leviathan Blade or some other gun.
Armor-
If ya want tocovert the hardest... Welll, go Nameless/Deadshot.
If you want to make multiple, make nameless, Justifier and Deadshot.
Trinkets-Damage damage damage. More damage.
