The Shredder is a polished Iron Sword described as capable of lowering enemies' defenses when used to attack.
How it works
The equipment entry describes The Shredder as a polished Iron Sword and says it can lower the enemies' defenses. Its effect field says to use it to attack. The supplied passage does not quantify the reduction or state its duration, trigger details, recipe, or unlock condition.
