"Easy" method to cut Seath's tail

Moonlight Greatsword made easy

Breaking the Crystal

All you have to do is to trick Seath into breaking the Crystal itself. During Seath's attack animation, go around it, - preferably by your right -, and cut the tail. You'll need a strengh weapon with a good vertical move set like the Zwei or a Club, especially if you are in NG+
