Bicheon Mastery skills - How do you feel?

[yongho]

I was curious about which Bicheon Mastery skills everyone thinks are either incredibly useful or incredible useless.

I've read enough on the forum to see that there's a general consensus Chain Sword Attack, Hidden Blade, and Killing Heaven Blade are "must-haves" for anyone choosing Bicheon. (and I 'think' the passive also)

I've tried Castle Shield in the Shield Technique series and because you can't attack while using it, it's a waste of SP. I've also tried Soul Cut Blade in the Blade Force Series and that seems like a waste of SP also.

The only skill I haven't been able to test for myself is the Sword Dance series so I'm not sure how useful that is. There's a blade guide on this forum that gives a description of the skill but I still don't really know if it's worth spending the SP on.

Here's the Blade guide with descriptions of all skills.

Here's the link to my favorite Blade guide. (Fly's SRO guide to the 3 most powerful builds)

Fly's "guide" is really no more than a quick overview.

I've got a 6x blader and I've found uses for all the skills, but I haven't had the sp to up the shield technique skills to make them worth using in real situations.
