This is t4, like the other Thebes weapons, but enchantable (like the other Thebes weapons). That's fine, I suppose, but the damage is far less than a Sayha's which is t3. It has 5 less base damage AND 2 less base Dex? The proc seems strong, and if effected by Int would likely make up for the damage, but it's a bit disheartening to see a t4 weapon with lower base damage than the t3.
Just thought I'd bring this up and get your input on it.
