What it does
Multiplies the Speed you gain while training by 4x (Rare).
How to get it
Trails Shop in the Safe Zone for $7.5K, or Robux. Equip it from the Trail menu after buying, or it does nothing.
Pro tip
Buy it in the Desert, before the Golden Pickaxe. Robux shortcut: Trail 2, 19 R$ (tier match is our best guess).
