"A miraculous stone that prevents all adverse effects, and boosts Defense & Magic Defense." - Flavor Text
The Constitution Gem (キ石 Ki Ishi) is an accessory that can be equipped by all party members. Equipping it increases both Defense and Magic Defense by 10, and additionally prevents all negative status effects on the holder.
In both versions of Skies of Arcadia, the Constitution Gem is an item that has a 1% chance of being dropped by the Florast enemies found in the Dark Rift. However, in the remake, one can also be obtained after feeding 18 Moonfish to Maria’s pet Hamachou.
