Sounds kinda cool. However I would suggest a few changes.

Copper is heavier than Iron, so maybe allowing it 10% Crit, -2 Durability, and +1 weight

For Armor, I don't think it should be like that. Infact, that makes it worse than quite a few armors.

Instead, I think it should give 5% Lightning Resistance, -1 DEF, and either +5 evasion, or +3 Magic Protection.
