i the only way - besides a CotW - to get this skill.
But as many people , me included, experienced, this skill simply feels quite weak.
As for the Set - I guess no one really tried to build around it after the mana cost reduction and the slight damage buff. If you want to try it anyways - go for it but do not expect to much
