Your power comes from the Thinker Entity. + Your power is dead and can't directly change your personality. - You have to learn how to use your powers. - If you use your powers too much, you could use up all its juice within a couple of decades. + Your powers may be slightly stronger than described. If you chose Character-Insert or Reincarnation, then: - You owe Cauldron 3 favors - You owe Cauldron fifty thousand dollars per Shard Point you use on powers. With powers you can make money pretty easily, unless you're a Ward. If you give Cauldron an extra favor then you don't owe Cauldron any money.
You can choose whether all your powers are distinct or facets of a greater whole, in either case they will be able to affect each other and/or synergize together unless explicitly stated. As your Shard is dead the synergies are imperfect and fixed at the time of Trigger.
