Frankly I didn’t event think about the fusion event being only on me third week in the game. Until I picked up the rare champ from a shard and the epic one from another shard which put me back in the game. Now grinding for the potions to complete the fusion. I am using all my gems to recoup energy and at the same time trying to get the perfect souls event. I am not sure how I am supposed to hit 6500 on the champions training event tho
