Oxidized Cut Copper Stairs are the final stage of oxidation for cut copper stairs. They have a distinct teal-green color and will no longer oxidize further. Lightning or an axe can remove oxidation levels, reverting them back to previous oxidation stages unless they are waxed with a honeycomb, which prevents further oxidation changes.
These stairs must be mined with a stone pickaxe or higher; otherwise, they drop nothing. They can be crafted from oxidized cut copper or obtained via stonecutting.
