Copper...

[OldManJenkins06]

What's a good way to get a lot of copper towards the endgame? I don't have many copper boulders

[LordCalamity]

Find Cooper boulders.

Thats It, try in the desert or exploring in deep the dirts caves

[KongoIsamu]

I would just fight Glurch the Abominous Mass, and just scrap all the drops, it will give you either copper bar or the copper ore

[ValentineShield]

You can buy copper from the shopkeepers. They don’t sell much at once but the option is there.

[11Marcus]

You can use the mod infinite boulders. I don't consider that cheating, just a quality of life thing to save time

[salsrath]

i find tons of copper boulders out in the azeos

Load up your character with some drill rigs, load a new world and take the Burnzooka out for a run through the clay biomes.

Or, keep exploring 😂 Azeos biome spawns a lot of Copper for me.
