If you're talking about Erzengal and his +3 italian sword I find it hard to believe that his "perfectly executed stab glanced". If it glanced then it wasn't perfect nor even good. Which is unbelievable cause Erz is killing machine
It wasn't Erzengel. The guy will probably change his setup soon, he wasn't doing great at all.
Also, when you start saying "italian" in the name of a weapon, you can already stop there. I know it's beast. Cmp influencing the unbalancers into his nationalistic schemes.
Finally, the italian sword is not a very good stabbing weapon either. Except with amounts of STR that will leave you helpless when you need a tactical advantage, stabs will glance for no reason. It's one of the best, if not the best straight sword at the moment though, especially for leftswing spam scrubs.
