Schematics are a group of items found in UnderMine. They are given to specific NPCs to craft the items they are for and unlock them for future runs (Thorium is needed to purchase these items). They can be found in different ways, from looting them from chests to killing bosses.
When unlocking a schematic that item is dropped and can be picked up for use in the next run. Multiple schematics of each category can be unlocked at the same time but only one can be taken with you into the mine. All extra unlocked items will be stolen by Pilfers.
Relic Blueprints[edit | edit source]
These blueprints are given to Wayland to unlock new relics. They can be found in Thorium chests and secret rooms. Some unique relics such as Selt's Egg and Holy Guacamole are dropped by defeating bosses, or given to the player by NPCs like Hungry Ghost and Wayland's Boots.
