|Casting Cost||4 Mercury Djinn|
Boreas is a Mercury elemental summon that is available in both games. When summoned, the screen goes to a giant robot-esque guardian in a mountainous setting. A large chunk of ice drops into the back of Boreas, and a little lever starts spinning, crushing the ice and ailing it down upon the enemy party. Boreas ends the attack by hitting the now frozen enemies with a powerful bolt of Mercury energy. To summon Boreas, one must use 4 Mercury Djinni. Boreas is the strongest Mercury summon in the first game and is still somewhat useful in the second game. Boreas is obtained automatically upon gaining 4 Mercury Djinn.
