Yeah, for most enemies you'll have 99.1% chance of inflicting status effect instead of 100% chance... I don't think that make such a big difference.Well Vhala is okay I guess, but its -500 LUK so say goodbye to Vhala status effect inducing skills.
You can do that, but I don't see the point. Hilstara need high DEF and MDF scores, not high ATK score.I put it on hilstara. A girl don't need luck when she can tank a nuke and say "meh".
