The Sigma Breaker is a wrench that Max will obtain in Dark Cloud 2. This weapon is only built up from the Poison Wrench and if you do so, you'll have the "Poison" and "Steal" ability. However, if you obtain this weapon, it won't have any special abilities. It has the wrenches' standard 5-hit combo, but its attacks are different, and very often, the 3rd attack of the combo will not hit the enemy unless it's lying on the ground. In the Japanese version, it continues to use the attack pattern that all wrenches before it use.
