I know the how Brave and Default work. But something I have not quite paid attention to is what spells like Free Lunch that 'Make MP cost 0 for "two turns"' ACTUALLY mean.
If I Brave 3 times (so when I am up, I do 4 attacks) is that "four turns" so my fourth attack will cost normal MP?
Turn 1: (Free Lunch, Free Summon, Free Summon, 40 MP Summon)
Or is that "one turn" and the next time I get to go I have four more free spells again?
Turn 1: (Free Lunch, Free Summon x3) Turn 2: (Free Summon x4)
Or is it the more complicated, All effects for that turn pretend you are on your first turn and but since I actually spent 3 extra turns I am now down to total turns affected - 4 uses.
Turn 1: (Free Lunch, Free Summon x3) Turn '5': (40 MP Summon)
