This is a small idea...
While doing pvp you often find you don't have any more protection than other players.

so i thought that having 2 stets of armor and 4 types of health kits might solve this. the hp will be place able on the ground and you just use it like food by pressing e on it to heal yourself but it also heals your armor that's if you are wearing any. The armor would be available at level 4 and the green armor will cost 250 gold and the blue armor will be worth 1 plat or 850 gold. The armor will give you an option to display it or not if the player doesn't like the look of it then they could just click on the display icon in their inventory.

Stimpack: a stimpack would be worth 6hp and heal 1 armor
This would be worth 25 gold in the shop

Healthpack: a healthpack would be worth 10hp and heal 1 armor
This would be worth 50 gold in the shop.

Medkit: a medkit would heal 18hp and a of 2 armor
This would be worth 100 gold or lower in the shop.

Berserk: if you want to include berserk which would heal no armor but restores the player to full health and gives them super strength on melee weapons enabling them to deal 4 more hit points. the super strength would last for 15 seconds.

Each of the health kits would restore your armor if you have bought any if you have not then you can't heal your armor with the health kits. Note the armor will be a 1 time purchase so it can be used and worn but if damaged to the point of 0 then it will take no effect.

Security Armor: security armor is colored green and will give you 6/18 armor near 50% and will cost 250 gold.

Combat Armor: combat armor is colored blue and will give you 18/18 armor 100% and will cost 1 plat or from 500-850 gold.
