Finally done with the event. Might have spared myself one bundle and still would be able to get a full clear.
Now just to farm up for the extra rewards in exchange shop.
Not sure if I wanna spend the Blueprints on Eliting the girls, since the price is so high. I think waiting for the Bluerpint shop to reset to see what 5* will be featured for the next week before doing anything will be the smart choice.
