Okay, so on site the mod is hosted on, I told you that my supposedly unbreakable Valyrian Blade broke. Well, it turns out it that all three Valyrian Blades can break. I'm quite sad. T_T
Take note, I'm speaking of the Valyrian Weapons that you can get from the blacksmith in Qohor. All three Valyrian Blades break, I don't know about the rest.
Here's a Screenie of All Three Valyrian Blades. The two One-Handers and the one One-Hander/Two-Hander. The rate at which the weapon breaks differs, either that or deterioration of the weapon carries on to the next battle. Sometimes it'll break like at the very beginning of the battle, sometimes it'll break after I've killed around +20 Men, then there are the rare times it doesn't break.
Also, don't know if it's only for Valyrian Weapons, but I had two of the same Valyrian Blades in my equipment slots and when the first one broke, so did my second one, weird.
All three of them are called, "Valyrian Blade".
