From publisher blurb:
When a warlock strikes a bargain with an otherworldly patron, they may seek some arcane secret or power, but the gifts over which they barter are as diverse as the warlocks themselves – some ask their patrons for immortality, while others would beg for the destruction of a foe. Others ask for abilities they might lack, or the means to undo a tragic mistake they’ve made. Whatever the case, a patron may be willing to provide what a mortal asks, but will the price be worth it?
Building off of the existing Fifth Edition rules to build a warlock character, Dark Barters offers warlocks 6 new choices for their Pact Boon class feature, from the ability to escape from impossible circumstances to the facsimile of a beloved companion to further expand the playstyle options available for warlocks with any Otherwordly Patron.
