From left to right: flint deposit, nautilus fossil, acumite ore, desert salpeter ore, mesa saltpeter ore, yellow basalt, void ore, magma cyst, mutite ore, echo ore.
Flint deposits can generate in any gravel in the overworld or nether. When mined, flint deposits yield 2-3 flint.
Flint deposits generate at a frequency of iron but in small numbers.
Nautilus fossils generate on gravelly ocean floors. When mined, they yield a single nautilus shell.
A nautilus fossil emits bubbles that can be seen from a distance.
Nautilus fossils generate at two times the frequency of diamonds, but only generate in groups of one.
Saltpeter ore generates in sandstone in desert biomes and in terracotta in mesa biomes. When mined, it yields 1-2 saltpeter and is affected by fortune.
Saltpeter's main use is to be combined with sulfur (see below) and coal to create gunpowder.
Saltpeter can also be used to brew potions of desiccation which give the "dehydrated" debuff. When dehydrated, a player's saturation is always at 0, meaning they get hungrier faster and cannot heal from food.
Saltpeter can be combined with paper to create firework rockets.
Acumite generates in stone caves at half the rate of iron and in similar vein sizes. It drops acumite crystals when mined and is affected by fortune.
Acumite crystals can be eaten to gain a good chunk of XP or brewed into water bottles to create bottles o' enchanting. This yeilds a similar but more variable amount of XP, but can repair gear enchanted with mending. Additionally, acumite crystals can be baked into acumite pies, which make consuming acumite faster and restores 8 hunger and 4 saturation per pie.
Yellow basalt generates in basalt deltas in the Nether. When mined, it yields one sulfur and can be affected by fortune.
Sulfur's main use is to be combined with saltpeter (see above) and coal to create gunpowder.
Sulfur can replace coal in the torch recipe, yielding twice as many torches.
Sulfur can also be used as a fuel, smelting a total of 10 items per piece. Coal smelts 8.
Sulfur can be used to brew potions of stench which give players the "nausea" debuff.
Magma cysts generate anywhere in the Nether. When mined, they yield 2-4 magma cream and 0-2 blaze powder. These drops are affected by fortune.
Magma cysts generate at 1.5x the rate of iron, but only come in groups of one.
Void ore generates in warped forests in the Nether. When mined, they yield 1-2 void fragments. This can be increased with fortune.
Nine void fragments can be combined to create one ender pearl.
Mutite generates in the end at the frequency and size of iron ore, and can only be mined with a netherite pickaxe. Smelting mutite ore yeilds one mutite.
Mutite is used to transform certain materials into other materials. These include most ordinary materials, stone variants, and wood types. Use JEI to view a full list of the possibilities of mutite. Leave suggestions for mutations you feel should be in the mod! More powerful mutations require purple mutite, which is crafted with one mutitr and one echo crystal (see below).
Lastly, mutite can be used to gain ender pearls. Smelting mutite yeilds ender pearls at a 1:1 ratio. Mutite can be crafted into a pure ender pearl by combining mutite with a popped chorus fruit. A pure ender pearl does not damage its user and never spawns ender mites.
Echo ore generates in the end at the frequency and size of iron ore, and can only be mined with a netherite pickaxe. Smelting echo ore yeilds one echo crystal.
Echo crystals are used to duplicate certain items. Most materials follow this pattern: combine one material item with one echo crystal to yeild two of the material item, essentially transforming the echo crystal into the desired item. Expensive materials may require more crystals to duplicate, and abundant materials may output more than two items per craft. Leave suggestions for materials you think should be able to be duplicated by echo crystals!
