Wrecker
From Legends of Cphera
Plate armor (Breastplate, Half Plate, Full Plate, and Enforced Full Plate), while exceptionally tough, is susceptible to certain weapon designs. A weapon with the that is described as a wrecker treats the armor as if it had a much lower hardness than usual.
Weapons may also be described as a Wrecker -2 or -4. If a wrecker -2 deals damage to an armor with a wrecker hardness of 4, it treats that hardness as two higher, 6. A wrecker -4 would treat it as 8, and so on.
