Alderite

Alderite is a HyperAlloy (aka Tier-3 Alloy) in MI, Its very important for buying items and packs alike. Alderite has a very complicated alloying recipe:

50 Gemirite Metallic Plates + 30 Aurora + 45 Metallic Plates + 120 Granite = 4 Alderite

As you can see, the recipe involves multiple Tier-1 and Tier-2 Alloys, which means that making Alderite is, to quote MI's Dev, Hell

He also said you will need about 2.5k Alderite to finish off MI's late-late-game. I did some math and to make all that Alderite you will need in total:


 * 31,250 GMPs
 * 18,750 Aurora
 * 28,125 Metallic Plates
 * 75K Granite
