I have full battle mage, full Cavalry set, and only the feet, hands, and legs for Infantry, monk, acn, and lnc rings only, and did brayfox upwards to 50x. I had a string of maybe 8x where all that dropped was cavalry belt, and battle mage gear.

I will get my darn belt, head and body! Now matter how much longer it takes.

Oh and for all the ones that have trouble with foe strikers good luck. It took me a while to get that set...but totally worth it.
