Dragoon or Monk

[Zamii]

I'm curious about something.

If Battle Litany raises Critical hit rate, doesn't that mean that it raises both critical damage and critical heals? In which case, it is not only an offensive buff, but also a healing buff. (And defensive buff for something like a critical Adloquium that further mitigates damage.)

Is this correct, or does it work differently?

Also, piercing debuff extends to MCH as well, right?

battle litany only affects critical hit rate and not critical hit damage, unlike the critical stat found on gear.
this means that it does help heals to crit more often, which is especially useful for sch.

and yes, mch currently does piercing damage, so both bard and mch benefit from having a dragoon in party.
