The idea this is the part that actually needs to be talked about
Armors gain a new accessory slot (except Skelly, Jelly, maybe ponchos and armors mentioned below) which adds onto the upper body. I'll call them 'upper body accessories', they add onto the chest and shoulders like the guardian armor does.
It may result in slightly less 'helmet dominance' by giving armors equal slots to helmets.
I would say that some should be token rewards but that's not the point of the suggestion.
What already exists or, The 'why I think it's possible to do this already' part
There are currently 3 armors that are just a normal armor plus an asymmetrical addon. I checked the game files and the armor consists of two pieces
-Azure Guardian = Cobalt + Left arm armor, a cape and shin pads
-Snarbolax Coat = Wolver + Left arm armor with a large spike on the shoulder
-Almirian Crusader = Plate Mail + a large shoulder plate with three cone-spikes, a cape, a loose string and some fur.
Then there is the Guardian PvP gear that goes on any armor it wants
Designs for these new things or, The part you don't actually need to read
Lichen on shoulder
Mecha knight exhaust and other stuff
A gear cut in half, ripping off Almirian Crusader
Something based on Seerus's clothing
An item covered in fur like the Darkfang shield desc. leaving this here for now
Suggest more if you want.
Changing the title constantly because I don't think it's working well
Might want to upload that pic. Your thread will get a lot more attention if you do.
