i fixed copper

people have been shitting on copper too much for being useless so here I am "fixing" it (totally my opinions)

copper set would have 3 times durability of iron but it will oxidise and each time durability and other stats (speed, damage,etc.) would be significantly lowered.

scraping them using axe would un-oxidise them and waxing them would prevent oxidation.

Copper set would have all disadvantages as they have now so they won't replace iron but they would have more reason to be used.
