Anyone happen to know the base duration on this spell? And does Focus Barrier work like blurs/guards in that it will stay on the persons after the group is disbanded?
There is no base duration. The spell stays active as long as the caster retains the mental capacity to be able to maintain it, which may be for hours or even days. It will drop if a group is disbanded.
1213 Mind over Body also seems to have a infinite duration, as long as you remain in the group you maintain the benefit and the caster maintains the benefit until...?
Until you cast another focus, are stunned long enough for the hidden renewal tick (30 or 60 seconds, I forget) or STOP it. Other types of incapacitation than stunning might do it as well.
