It's me again and I'm back with yet another idea:
Armor Sets (or at least the effect of Armor Sets)
Examples would include:
Night Vision Goggles
Ghille Suit
Fatigues
Dog Tags
Boots
Effect : +1-3 damage with Firearms, +5% accuracy with Firearms and Bladed Weapons.
Scrubs
Lab Coat
Bio-hazard Suit
Plastic Gloves
Lazarix Access Tag
Effect: +5 to Healing
Cows Skull
Noose
Patchwork Skin Suit
Burial Shroud
Toe Tag
Effect: +5% accuracy with Teeth, +5% chance to infect
Amulet
Eyebrow Ring
Cloak
Fingerless Gloves
Mantis ID-Badge
Effect: +3 Plasma Feeding
A more viable alternative to making it work would probably be to turn them into a recipe and the resulting item would take up the equip slots of the items used to make it. I left out anything Armor related to try and simplify it further.
