For Psychonauts 2, we need a reason why the player doesn't have all the powers they had in the previous game. That is because all the powers were generated from the merit badges. Razputan has to collect a new kind of item to make those psychic powers generate within him in order to permanently have the powers.
He will also learn other new powers like
Cryokinesis- Ice version of Pyrokinesis
Electrokinesis- Electric version of Pyrokinesis
Teleportation- Used to warp to other checkpoints in areas
Replication- Creates a mental image of Raz to set off traps or distract enemies to get certain items
