Uh... I'm a little bit confused by what this skill actually does. The description says the following:
[Increases Compound accuracy for maturing compound based on LK]
Based on that I was thinking it will increase the success rate of compounding but I thought there is no failure rate for this kind of action.
From what I'm reading it's supposed to increase the amount you get from using the materials onto the equipments. But does the luck stat have anything to do with it? Also there's web compounding and I don't exactly know what that's about but is it supposed to be better than a maxed out 'Compound Master' Skill?
