Ah, so you wish to bestow a special ability onto your weapon! Good idea. Enchantment? No worries. Bestowing a special ability won't make the enchantment disappear.
Oh, and I have some important news. The skills of all the blacksmiths have improved greatly. You don't need to go through the Blacksmith of Mammon or the Black Marketeer of Mammon to bestow a Soul Crystal effect onto weapons anymore.
It looks like they stopped bestowing special abilities. Wait, did you know this already?
Choose the capabilities you wish to add to your weapons!
