None of the paragon package powers are meant to be 1/ever - they all refresh at logistics, like any spell or martial skill. You are also free to exchange any "Choose one" skill you like for any other valid subset: you can change your cloaks, your selected Magic X spell, your "treat carrier X as normal", or your Deception of Chithiss.
The only exception is the Elf high magic points - those function exactly as normal high magic points do, including restrictions based on caster school, 9th level spells required, and 5-day duration.
