Black Mage Sanctuary - A Guide to DPS

[Sylvain]

I do want to clarify something though. So you only use B4 with opener, when triplecast is off CD, and no foul up correct? If foul is up, you use the 3.0 with 5 F4s?

That's what I understand.
Basically, if there's nothing else to do, use it.
It's the ultimate filler.
