They are stackable. Anything that converts is an effect on its own. Anything else that converts to the same stat using a different stat for converting, will not stack. This is true. So if you use a BB/SBB that converts half of REC to DEF, then you use one that converts half of ATK to DEF, the on that initiates last, cancels out the first since it's the same buff type.

However, using a BB/SBB with one of those that includes increasing DEF by 100%, will stack. Though keep in mind that the ORIGINAL values are the ones that are taken into use. Not the current values.

So if you have 500 REC and 1000 DEF on a unit, the outcome of a 1/2 REC to DEF and a 100% boost to DEF would be 2250(or 1000+1000+(.5*500)).

If you don't know what stacks, during any quest or battle(aside from the arena), tap and hold a unit on the field after using BB/SBB. This gives a detailed status for each unit, their extra skills, spheres, and all the buffs/debuffs they have currently. So if you use other BB/SBB and wonder if they stack with another, use this method to easily check which effects stack and which don't.
