Basically take a popular armor and make it look like it got mobbed by a group of monsters.
Jelly costumes with wolver bites out of them.
Skolver costume with burnt sections.
Bomber costume with what appear to be Jelly spines lodged in them.
Plate mail set with several heavy dents, and maybe a broken twig sticking out from a joint here or there.
etc.
Also include torn or broken prismatic accessories.
Maedates with one side burnt and broken off (or with jelly globs on them)
Torn Vitakits, Cracked glasses and goggles, broken Vees, frayed Mohawk, Vented Visors with jelly dripping from one side, cracked wings, etc
I gotta admit, this is the most original content I've seen in weeks. Aside from the additional dialogue suggestion from earlier. Maybe Bolted Vees with one side cracked/missing, like with that Maedate.
