Wrenches

Wrenches are a currency exclusive to Scrap Clicker 2, unlockable at x100 Stars through the Skill Tree.

Obtainment
Once unlocked, each merge awards the player 1 Wrench. At x105 Stars, the player can then purchase a Tree Upgrade which increases Wrench production so that each merge is worth 0.1 more Wrenches than the last. Later on, the player can unlock the Wrench Storm to get even more Wrenches.

Spending Wrenches
Wrenches are primarily used in the Scrapyard v4, multiplying Brick production by 1,5 with each level. Wrenches can also be spent in the Skill Tree to increase Scrap production, Steel Beam production, and unlock Tires.

Trivia

 * Wrenches (Unlocked at x100 Stars) and Tires (Unlocked at x130 Stars) can be seen as a part of the Team Map's car before unlocking them. (Map is unlocked at x50 Stars)
