When you use a Power outside of its normal phase (eg, during the Invader Phase via the Rouse the Spirits event), if Repeats have been granted to you (eg, from Gift of Strength), can you use them then?

Changed answer: No. Unlike Lightning's Boon or Sky Stretches to Shore, you're not actually changing the Power's speed, you're just using it (once) ignoring speed. Repeats can happen in the phase matching the Power's actual speed.
The first-pass answer was "yes" based on the idea that these things changed the Power's speed, but that proved the wrong direction.
Note that this only applies to granted Repeats, like from Gift of Twinned Days or the like. It does not apply to Powers which have "Repeat this Power" as one of their instructions; those can and must be Repeated immediately as an action triggered by the initial use. (After any other triggered actions.)
