Hey Sedy, the skill 'Iron Grip' is in the middle tree of the Soul Blader page, it currently requires sp expenditure in the 'Subdue' series of skills and as a result it's not specced into, it also is different in terms of what it does.

Subdue reduces physical hit so it allows the evasion build Merc/SB to work more efficiently.

Iron Grip pulls you to a target and then immobilizes it. It fits in more with the skills present in the left skill tree rather than the middle one and I would quite like to use it without spending so much SP in a few subdue skills if possible, it could also be a standalone skill like Charge. Could you take a look at it Sedy and see what you think?

Cheers!
