Tactics
Having mastered magecraft from the Age of the Gods, Medea possessed extraordinary power as a magus. However, because her physical ability as a Servant was the lowest, she was at a disadvantage in battles against Servants with high Magic Resistance. Consequently, she faced the battles with basic tactics, avoiding personal combat to the best of her ability and using her Dragon Tooth Warriors as pawns. Even in combination with Kuzuki, he was the attacker and she bore the role of support with magecraft. She laid out a stratagem to summon Servant Assassin (Sasaki Kojirou) and order him to guard the Ryuudou temple gate while she gathered mana and used her own Noble Phantasm to destroy the other Servants' contracts and make them her allies.
