Golden Yggralith Hearts are intergalactic materials in Xenoblade Chronicles X. They are dropped by Yggralith Zero if the fighting team drops its RP to zero. They can also be obtained by exchanging Reward Tickets at the Network Console. Two of them are needed to create an Ares 90 Skell. One apiece are needed to craft the True Comm, True Cords, True Bangle L, True Bangle R, and True Plastron armor set.
