The two undead summons offered are extremely tanky versus earth and poison based enemies, though later in the game the 10% knockdown chance is blocked by one rank of Body Building, and the DPS on them is not the highest. Best Skills: Oath of Desecration for your DPS, Absorb the Elements to buff your tank, and Drain Willpower/Soulsap to shut down a boss. Witchcraft is the only ability that does not unlock any talents.
