When the Aegis levels up and gains more basic powers for the suit, he can form, change type and dismiss the suit if he likes or needs it. This takes a specific action depending on the new type of suit (swift, move, full-round), and does not require paying power points or customization points.
To confirm that I really understand: Now the Aegis can learn (or gain) non-basic powers for the suit and so he needs to change from basic power of i.e. Astral skin (nimble, speed and so on) for a non-basic power i.e. Darkvision that need 1 pp. Finally in the morning he can choose from basic to non-basic powers paying power points too, if he wants to change from basic to non-basic powers during the day he needs to use the reconfigure ability and then the customization points?
