This weapon is an excellent carrier for weapon buffs due to its 3 turn usage. A Mech-buffed Wrench with one Deadly Poison adds up to a 5 Attack weapon with 3 Durability. The damage buff is active while you have a mech, in other words the buff goes away and comes back along with any friendly Mechs present on the battlefield. This means that the enemy can try to slow you down by clearing your board, but you can always wait until you draw a new Mech and play it to immediately reactivate the weapon's Attack bonus.

The most obvious Mech choice to synergise with the Wrench is Goblin Auto-Barber.


This weapon appears to rightfully belong to the Cogmaster, who likewise gains +2 Attack when a friendly Mech is on the board.
