The Icestone (氷竜石 Hyōryūseki, lit. Ice Dragonstone) is a Dragonstone that appears in the Archanea Series of Fire Emblem Series. Infused with the compressed power of an Ice Dragon, the Icestone allows a Manakete to assume the form of such a dragon, granting them numerous statistical bonuses that enable them to engage in combat in the process. Notably, the Ice Dragon specialises in Skill and Defense, allowing for Manaketes using the Icestone to be highly accurate in their attacks, alongside being able to absorb most physical attacks.
