Deathstalker III: The Warriors from Hell(1988)

Deathstalker’s back—and this time he’s facing off against Troxartes, an evil wizard with a zombie army and two magical jewels that hold the key to the lost city of Erendor. Teaming up with Princess Carissa, Deathstalker must protect the third gem, storm a heavily guarded fortress, and ride a bolt of lightning straight into battle.
