So I pulled a vicious bloodblade of wizardry (with a 10% splintering mod) off a raider. Mods looked awesome, so I used it on the next raider. Durability went to 6 from 75 on one mob!! What's with that? Is this how splintering weaps work? Are they essentially a single use item? This is the first time I have used one, so have no experience with them.
