You can find carbon ore, smelt it into carbon ingots, and make a carbon block. Now you can craft tape, and with that and a carbon ingot, you can make graphene.  A slimeball is returned to you after a graphene craft.  Then you can craft upwards to the Graphene Block, Graphene Chunk, and then Graphene Ingot.  With other resources, you can make Energetic Balls, Shells, and Cores.  The Energetic Balls can also come from the Energetic Ore.  With all those resources, you can make the powerful Tech Set.  It has insanely high armor, is unbreakable, and has special abilities...

Helmet = Night Vision

Chestplate = Saturation

Leggings = Speed

Boots = Jump Boost

Full Set = Resistance

It is very powerful, but very expensive... Here are all the materials you need to make a full set (Set aside the next decade...)

2937 Sugar Cane (Nearly 46 Stacks of 64!)
1958 Slimeballs (If you don't count the ones returned from crafting)
979 Carbon Ore
131 Coal (If that's how you choose to smelt the ore)
32 Iron Ore
4 Diamonds
2 Nether Wart
1 Rotten Flesh
1 Blaze Rod
