Magic Defense: 50
This Magus seems like an incomplete version of the North Cape fight. At first he will only do scythe attacks. If the only attack was by the Masamune, it will be switch between wasting a turn and a different attack with no visible difference. Below 50% HP he will always attack with his scythe, and counter with a scythe attack, Fire 2, Lightning 2, or Ice 2 randomly, unless the attack was by the Masamune.
