I am currently in a game with a GM/DM that is saying that Warlock and Sorcerer Magic Items are subclass specific.
That they are not available in stores, they would have to be gifted by the Patron or Otherworldly Power, furthermore that a warlock or sorcerer from a different subclass would not be able to use them.
While I understand this would make sense from an ingamein-game roleplaying sense, are there any rules RAW that suppoertsupport this, or are warlock/sorcerer items usable nyby any that pick them up?
