I accidentally four stared Diabolist. warmaiden, heiress, and spirithost. This was after I ascended them all the way as well and got most of them to 30. i just went back to look at the fusion for relic keeper, and it says I cant fuse them..... because they're supposed to be 3 stared. is there any way I can get my champs reverted back to 3 star? I can send screenshots as proof.
