Sitting in a stall in the bathroom, Jayce opened his system to look at his rewards. He skimmed over the other rewards as he focused on the skill.

[Contract Creation]
[During the Demonic War, demons would trick humans into signing contracts. By lending them demonic energy, the humans would in return swear loyalty. Although the demonic energy would strengthen them, it would corrupt them over time, slowly turning them into demonic beasts.]
[To form a contract, three rules must be followed at all times.]
[Rule A: All conditions and requirements must be written on the contract for it to come into effect. Verbal agreements do not affect the contract.]
