How do you illuminate an angel? And what does it do?

If you have angel unlocked, it may ask seraph stones, bless stones and angel tears to illuminate them, in unbreakable bond. And each individual angel gives some portion of hp, atk, def and agi mostly . And angels gives combinations. Which when lvled through bonds give various stats, for front row or back row, or whole party, or character only.
So it helps improve you and your heroes . You can lvl them Using wisdom of spring, or spare shards of already unlcoked angels. Like you have Unlocked Fortuna and have 50 shard in invenotry, those 50 shard can be used in unbreakable bond, to lvl up your angel combo . Atm some issues with seraphim shard.
