The blade is seems really nice until you read the last part. The way i understand it any character wielding it gets a -5 will penalty and another -5 will every time they are critically hit? This is a debuff to your own character and not to your opponent? Am i reading this wrong?

 

 

that's correct, there's an enchantment to turn it off(silence the dead)

yes, its a debuff

 

 

you can enchant it to remove the debuff

Tks!
