Wyverns have high HP and Defense, so they may take more than a few hits to kill. When left alone, they can cast Cyclonic, which takes away 15/16 of everyone in the party's HP. They are weak to Ice, so Celes should cast Blizzard against them. Locke can stealDragoon Boots from them, which can be sold for high profit.
[view·edit·purge]A wyvern is a medieval European mythological winged creature with a dragon's head, reptilian body, two legs (sometimes none), and a barbed tail. They appear in many crests of Europe's ancient families, symbolizing strength. The word wyvern comes from wivere, which means serpent.
