2.3 BiS Bard Equips?

[Ooshima]

Considering 1965 MP lasts about a minute and 1 PIE = 8 MP.

2381 PIE needed to sing foe requiem for 10 minutes

But this doesn't take into account natural MP regeneration. I don't know the value for that.

First thing, 1PIE=8MP is wrong for BRD, or any class/job that are not caster. 1PIE = 5.26/5.27MP for BRDs

Battle MP regen is 2% of your max MP.
