How to Get Copper Plates

Copper Plates can be made from Copper Bars in the Processor. You’ll need 3 Copper Bars for every Copper Plate so in total you’ll need 24 Copper Bars to make 8 Plates. If you’ve not made a Processor yet, head over to our guide on how to unlock and build one!

How to Get Copper Bars

Copper Bars are most easily obtained by cooking up Copper Ore in the furnace. Copper Ore is the most abundant ore in the mines. It can be found on the first level of the Abandoned Ruins and you’ll be able to get hundreds of the stuff in no time. You’ll get the most Copper Ore from mining big Copper Crystals found in the mines, but you’ll also get some ore from clearing the blue-brown debris that blocks your path. If you get all of your Copper Bars from mining Copper Ore, you’ll need a total of x72 Copper Ore for the Copper Plates.

You can also get Copper Bars by recycling Copper Scraps. Copper Scraps are a common drop when quarrying the junk piles in Eufaula Salvage Yard so if you have a bunch of Copper Scrap it’s worth recycling it to get some extra materials. As with all recycled scraps, the drops aren’t guaranteed so this isn’t the most effective or reliable way to make a bunch of Copper Bars.

Copper Ore is found on every level of the Abandoned Ruins.

How to Get Rubber Tubes

Rubber Tubes can be obtained in one of two ways. Firstly, you could recycle a bunch of Rubber Scraps in the recycler in hopes of getting the 6 Rubber Tubes you need. Rubber Scraps can be obtained from Junk Piles and Rubber piles in Eufaula Salvage yard.

Secondly, you could make Rubber Tubes using the Grinder. To make 1 Rubber Tube, you’ll need 3 Rubber. In total you’ll need x18 Rubber to make 6 Rubber Tubes. If you’ve not made a Grinder yet, head over to our guide for more information on how to unlock and build one!

Before you can make Rubber Tubes in the grinder, you’ll need to purchase the recipe from the Commerce Guilde Store. It costs around 44 Gols depending on price fluctuation.

How to Get Rubber

Rubber can either be obtained from recycling Rubber Scraps, or it can also be found from just digging in Junk Piles. Make sure to check out Eufaula Scrap yard every day to get as many resources as you can!

How to Get Bronze Pipes

Bronze Pipes can be made using the Grinder. To make 1 Bronze Pipe, you’ll need 2 Bronze Bars.

How to Get Bronze Bars

Bronze Bars can be made in the Furnace with x3 Copper Ore and x2 Tin Ore. You’ll need to build a furnace before you can forge Bronze Bars yourself!

The main way obtain these materials is to mine them in Eufaula Salvage Abandoned Ruins.

As outlined above, Copper Ore can be found in abundance in Eufaula Salvage Abandoned Ruins. In addition to the x72 Copper Ore needed to make the Copper Plates, you’ll need an additional x24 Copper Ore to make 8 Bronze Bars for the pipes - for a total of x96 Copper Ore.

Tin Ore can only be found in the mines once you’ve reached and unlocked at least the 3rd level of the Abandoned Ruins. To get to deeper levels of the mine, you need to search for door ways and holes downwards - most of the time they’ll be hidden behind depris so you’ll need to dig through it. It can be mined from silver spikey crystals. Once you’re at levels lower than the 3rd level, tin ore is very common and easy to mine. To make 8 Bronze Bars, you’ll need x16 Tin Ore.

Alternatively, if you don’t fancy going mining, you can purchase Bronze Bars from Hammertime - the smithing shop. Prices fluctuate in Sandrock, but one Bronze Bar will cost around 45 Gols. Or, you could purchase some Tin Ore and Bronze Ore from Eufaula Salvage Shop. Bronze Ore costs 4 each and Tin Ore costs 8 so it’s cheaper than purchasing the Bronze Bars outright.

How to Use the Hydrogel Door

The Hydrogel Door is a required build for the Moisture Farm Blues main quest. Before you can rebuild the Hydrogel, you’ll need both the Hydrogel Door and the Hydrogel Core.

Time to fix the Hydrogel!
