Gold : Used as a currency. Everyone starts with 100, and there isn't any way to generate more other than through trade, and sent you the other details through the PM
Shadow : A material that drops from flesh mutalids, maybe could be used by Sarti to give them invisibility as armor? It would be completely black
Hay : Could be crafted from plant matter, could do something with horses
Plastic : Not really sure how this would be crafted, would look like glass but be more durable
Cloud : Would be cool if you made some clouds, this could be a cushion for fall damage and used in lightweight armor
Water : Instead of having the buggy water in baseplates, you could make this a material
Wire : Could be used later on when events are allowed to stop a lot of OP stuff like manipulating named bricks from across the map
Spike : We need some sort of trap. Touching these would lower health and could be crafted out of stone, though would be very expensive
Silicate : Could be a rare material found in the underground mountain, which would be very close to lava. Very, very durable material that can also make for amazing protection totems.
And
Mihtril: Nice to make armors, maybe stronger than calcite and weaker than nithlite and bad for swords, stronger than stone sword but weaker than the obsidian one. You can get in mountains.
Iron: you can make armors, daggers, swords, arrows. Better than stone but weaker than surtra. You can find it only inside caves
Arcane wand: Turns iron into arcanite and makes mobs run away from you when equiped. It will consume 8 faerie dust and 8 of wood
Arcanite: Only works to makes arrows, daggers and swords, these are weaker than sanguite, but with more magic atributes than Sinnite. You have to make it when having iron in the inventory and using the Arcane wand.
Elven Wood: Its basically the normal wood but with magic atributes. You can get it by cutting off an Elven Tree
Bucket: (If you accept GMOs water request) Can be made of iron or wood. Allows you to pick up water from the lakes, rivers, oceans...etc and save it in your inventory
Aquametallisynthesis wand: (If you accept GMOs water request) It turns water into aquatum and allows you to walk in the water when equiped. It will need 8 faerie dust and 5 of obsidian to craft.
Aquatum: (If you accept GMOs water request): You can craft armors, daggers, swords and arrows. Stronger than calcite and weaker than sanguite. It will allow you to breath under the water
