I suggest there should be a system for weapons and items called "item experience". It would be shown like this:
e.g.
Level 7 (heat) [level and heat progress to next level]
Antigua [name]
Attack Power [power]
2.2 bars piercing [damage]
8 bars speed [speed]
Charge Time Reduction: Low [UVs, bonuses, status, etc]
54 - Used [experience]
*** [star level]
I still haven't told you what it is yet, have I? I'm going to now.
Well, experience works like this. You get an item and equip it. Let's say it's a Wolver Cap. The experience shows 0. You go into the Clockworks. You complete a level. Your experience now reads 1. You complete Gloaming Wildwoods and kill the Snarbolax with it. It now reads 4. You do Moorcroft Manor through Depth 13 wearing it. It now reads 10. Have you figured it out yet?
Yes, item experience tracks the amount of levels you have completed while wearing the item. There'd be different ranks. When you first get it, it'd read 0 and be labeled "Brand New". Complete 10 levels with it, it'd read "New". Ranks:
Brand New: 0-9
New: 10-24
Your's: 25-44
Used: 45-69
Slightly Worn: 70-99
Worn: 100-134
Marked: 135-169
Scratched: 170-219
Scorched: 220-269
Damaged: 270-324
Battle-Worthy: 325-379
Decorated: 380-449
Veteran: 450+
It would be purely cosmetic and not affect the weapon/item in any way. Just a way of knowing how many levels you've used it in. And other people can inspect you and sort of tell how long you've been using it. Wouldn't it be cool to have your gun or sword a Veteran or Battle-Worthy?
That actually sounds cool +1
