Clarification: Lockjaw - King's Best Friend

Hey guys,
This seems like it should be an obvious answer but I thought I'd check just in case.
In the Deadpool set I got the card Lockjaw: King's Best Friend. It says:
While Lockjaw is active, before your Clear and Draw Step, name a non-Sidekick die. If you draw that die, gain 1 life and each of your Lockjaw dice gets +1A and +1D,
Is the bonus to A and D a permanent one or just until the end of turn?
Thanks for the clarification!
