Otherworldly Patron: The Accursed

Many warlocks seek and beseech power from immortal beings or powerful fiends and monstrosities. In exchange for service they are given tremendous magical abilities. However, in your case an ancient being has placed curses upon your very soul. These curses may be a burden, but how you use them will determine your true strength. Many questions will remain unanswered until you grow stronger. Like, what does the entity want from you? Possibly, how could you separate these curses from you? The path you take will be difficult and full of hardships. Nevertheless, power is power even if it is accursed.

Your DM may make changes to this class depending upon the situation. They can add their own curses as well. Furthermore you as the player can discuss any ideas about curses you have. Your DM has final say on the matter.
