House of reincarnation using 4* childs (Restoration)FORUM
Is it even worth it? It takes probably 50(?) 4* star childs and 120 blood gems to guarantee a 5* child. No matter how you slice it, I can't justify all that for just one 5* child. You might as well use your 120 blood gems on a blood summon and turn those 4* child into onyx instead of throwing them away.
