Warhammer Fantasy

Uttering a dark incantation, you summon a devil of Chaos. You choose the type, which must be one of challenge rating 6 or lower, such as a barbed devil or a bearded devil. The devil appears in an unoccupied space that you can see within range. The devil disappears when it drops to 0 hit points or when the spell ends. The devil is unfriendly toward you and your companions. On each of your turns, you can try to issue a verbal command to the devil . It obeys the command if the likely outcome is in accordance with its desires, especially if the result would draw you toward evil. Otherwise, you must make a Charisma (Deception, Intimidation, or Persuasion) check contested by its Wisdom (Insight) check. You make the check with advantage if you say the devil’s true name. If your check fails, the devil becomes immune to your verbal commands for the duration of the spell, though it can still carry out your commands if it chooses. If your check succeeds, the devil carries out your command.
