Yet to 3star the Flying Pegasus Knights map, so no plat on that yet. Got every other unit, though. I only started when the event started, too. I have managed to do a 100% kill clear just units end up dying and its by the skin of my teeth, too. If i had used a ranged damage bonus, or defence bonus, i would have probably got it. Though those seem a waste of SC, Hopefully after grinding the armours on monday i can just get it, then get the plat.
