You only need a skill of 1 to use Clineschmidt's Blade.
Considering how comparatively early in the game you can get it, and that you start the game with enough skill to use it, it's a score.
The puzzle in the game is broken, so obviously you'd apply the statue's button sequence as soon as you get there... instead of waiting to find all the puzzle stones.
There's also the idea that it's identical to a Mithril greatsword, but still Fast. That's almost as good as the vampiric quality.
