Untouched weapons or armour should oxydize or rust overtime .

This is a basic concept , that will spark more passive actvity in the game . 1) when an armour piece or a weapon/ tool is left in a chest or on an armour stand it shall rust .

2) materials concerned by this are iron and copper .

3) to restore or avoid this problem , use wax .

4) when in best quality and additional wax is applied, armor will shine in daylight .

5) possible new acheivment : «  A knight in shinning armour » obtained when an armour piece is fully waxed .

6) when the weapon or armour is found in a this state , it will have hp and hitpoints deducted , only to be restored when waxed and repaired with an anvil . 

7) thank you for your attention .
