Q 45

A: What happen when a spell that is normally dismissible by the caster is coupled with permanency?

I would guess it's no longer dismissible, but is it stated somewhere?

B: What happen when the beneficiary of a spell coupled with permanency is hit by a spell with opposite effects, where's it's usually described that it "counters and dispels" the other spell? (For examples, enlarge person vs. reduce person or vice-versa.)

Is the permanency-fied spell countered for the duration of the other spell? or fully dispelled?
