That's Blade for you.

Which is like, 40 max? I'm not sure how Brd merits work.
That means (this is only speaking with a Rng in the party, the origional case) that if I hit a 7 or above, then I already did better. With Snake Eye, that means I cannot Bust (so if I land on 8, that makes 9) and I automatically did better. Not to mention, this is over the course of 5min, not constantly re-applying :P

Only time I ever bust is if I test a roll of 6 (I only do on less important buffs), and getting two 6's. Double-Up'ing a 7+ is just stupid, reguardless. This is where Snake Eye comes in once I get it :3

To top that off - Chaos Roll effects /ra too. Is there a Brd song that increases Ratt? (of course, Chaos roll is only good if the person has high attack, since it works with %s)
