The Scythian Wild Woman is an infantry hero in Age of Empires II: The Conquerors. She makes campaign appearances in The Great Ride and The White Elephant (renamed as Nat Enchantress in the latter) and is available in the Scenario Editor.
She uses the same model as Joan the Maid, which is probably why she also takes bonus damage from anti-cavalry attacks. Like other infantry, Scythian Wild Women are affected by all upgrades that affect infantry as well as any other bonuses that affect them. As a hero, she cannot be converted and can regenerate health.
