Unlock a random Metallic Block recipe you don't already have unlocked
— Item Tooltip
Metallic Block Recipes are a type of unlocker that can be crafted at the Runecrafting Bench, uncommonly obtained in Miner's Troves, or very rarely obtained in unique ores. When used, they unlock a random metallic block recipe the player doesn't already know that can be crafted at the Cube Converter. If all recipes are known, they will be unable to be used but can be deconstructed into Blank Scrolls.
