A warlock is defined by a pact with an otherworldly being. The arrangement is similar to that between a master and an apprentice. The warlock learns and grows in power, at the cost of occasional services performed on the patronâ€™s behalf. This additional arcane spellbook has all of the patron, origin, and tradition spells that warlocks, sorcerers, and wizards might discover. Contains 18 durable, laminated cards including: 16 for Warlocks, 1 for Sorcerers and 1 for Wizards. The perfect supplement to complete any arcane spellcasterâ€™s collection of spells.
