I have not tried it, but when you reset an ascended champ it will only return them to their current enlightenment number and radiance number. When you enlighten and ascend them the information attached to their serial number changes which is (I believe) a permanent change to the NFT. When you sacrifice a Ascended champ to increase radiance level it asks if you want to get rid of the champ, so I think you will lose all the soul stones and sacrificed champs that went in to the champion... 😒
@@MikeGoG583 that's unfortunate :( i like to build my derisda too but its too late when i learn that i can use ascended hero to upgrade the radiance level.
