The temporary effects of powers, whether yours or others', can now become a permanent feature. Whether it's Vista's distorted space or Othala's power that is the target of this ability, they can both be made to persist indefinitely. You can only have a limited amount of permanent effects at once. The more powerful the effects the less you can maintain. Maintaining only a single type of power is easier than maintaining multiple types of power at once. You can dismiss the effects on powers at any time. If taken with Negentropy you have no limits on permanent effects.
