Usefulness of Skills

Like how Slow Poison is useful? I mean come on, there are green pots or even Detoxify for that.

I've never had a Star Glad, but I've heard that Union is how you farm DG ghosts with it. And I think I've seen a few people killing it very fast the damage numbers showed like a bunch of Water Balls hitting Scaraba Queen (watch people confuse over how I'm comparing Union with Water Ball). Well, I'm not sure if they spam healing items like there's no tomorrow or what, but Union is somewhat useful that way.
