The Gauntlet's Transmuting Pool is a Module commonly used to obtain Grey LEGO Bricks during Ranks 8 and 9. Guests must spend one White LEGO Brick to click the Module. When clicked, the Module has a chance of giving the guest one Grey LEGO Brick. The owner receives one Grey LEGO Brick per click, with a limit of one per harvest. It is almost identical to the transmuting pool of its enemy, the Mantle's Transmuting Pool, except the Mantle's Transmuting Pool uses one of the owners White LEGO Bricks and the guest must spend a Black LEGO Brick.
