Strategy
The Ancient Wyvern may appear very menacing at first and you may think that you are in for a difficult fight; however, this is not the case. Right as you enter the battle, if you take a right and head up the side of the castle, this boss will become a cakewalk. As soon as you're at the top, roll on the platform below. After this, wait for the boss to stop breathing fire and, as soon as he's done, drop for a plunging attack. Doing this guarantees an instant kill.

An alternative is to use ranged weapons.
