The Final Boss in Deadly Decks: Curse of the Arachne. The Spider Mage is an ancient magus who absorbed accursed Arachne magic until he became a creature of psychotic consumption. With the Life-giver Orb, the Spider Mage has the ability to raise the dead and control undead creatures. During the final battle, the player must fight not only the strength and violence of the Spider Mage itself, but also the Spider spawner that creates minions who evolve, and the orb which summons the undead to fight by their side.
