There are three categories of abilities in Powers (p. 153-154). They are Always On, Switchable, or Transient. Modular Abilities are not Always On and they are not Switchable, so they must be Transient. Modular Abilities are 1) normally off, 2) the user must trigger it every time they want to use it, and 3) the effects occurs an instant and immediately shuts off (for example, changing point allocation with Cosmic Powers and Slotted Cosmic Powers takes 1 ready action per ability).
