Refreshed my browser and that took care of the banner missing issue. I also got a Mage Multiplier when I tested the chest; wish it was that easy for a building I wanted, lol! The tournament provinces that have mages as the key unit are Marble and Gems, both of them are my boosts, and I use a combo fighting/cater for tournaments; as heavy on the fighting as I can. So, I can use it. I wasn't going for it because both those boosts are over 600%, with gems being 670%. I figure I'll hit the max soon and I've just entered fairies. From what I see so far, pop/culture is going to be my immediate concern in this chapter so I am waiting for those days. Not ready to go all in on double days to try for the 3rd prize until I see the results from this event.
