So right now I'm in my "next phase" of bringing my Hu (Hunter) subclass to 75 as a main with bringing a subclass Fi as high or to 55. Depending on where it will be at when I reach 75 as a Hu Main. I've been reading a lot about "Perfect Guard" and see it a lot in the Hu Skill Tree.
What I was wondering is how do you execute a Perfect Guard. Is it by chance when you invoke it in battle? It didn't seem like hitting it during the red circle from a last attack made a difference. Plus now gaurantee a monster is going to attack when/if that even worked.
Is it a matter of a chance attack when invoked not doing any damage that triggers it?
