Every time I see an item that's one of a few possible sets, I can't help but to wonder if you get the bonuses for multiple sets at once with one item. Take the O)din's Blessing for example:
Set Bonus with Valkyrja's Shield[1], Fricca's Circlet:
Def+2
MDef+5
Each upgrade made to the headgear raises MDef instead of Def.
Set bonus with Fricco's shoes, Falcon Muffler:
Agi+3
MHP+5%
MSP+5%
Would having all the gear on multi-set items give you all the set bonuses normally? And are there any exceptions to the norm?
