Demon Soul fuses the warlock's soul with his or her demon. This provides warlocks with a self-burst cooldown to use. The specific effects granted by Demon Soul depend on the demon chosen. Demon Soul lasts for a certain number of charges or until it expires (around 20 seconds), depending on the demon used. 2-minute cooldown.
