Never used it.
On my first play-through I mainly used Ruins Greatsword and the heaviest armor available.
Second playthrough was hooked claws with occult infusion into the bird claws once I got them, always light armor class and dragon incantations for range and blunt damage.
Third playthrough was the Crucible knight roleplay, with Ordovis's Greatsword for funny stunlocks. But I quit midway because I got bored and it was too similar to my first run.
My forth run is sorcerer and I'm pissed I have not good counter to runebears. Cristal release sometimes does it, but is risky.
