RNG Relic+2/AF2+2 Help

Does anyone know if its possible to swap both bodies in precast/midcast to get the benefits of both? I.e. the 5% chance to double shot with augmented relic and all the nice things that come with af3+2?

Any help would be great.

I would think velocity shot would be akin to fast cast so you would need
Fixed. The velocity shot from sylvan is akin to equipping fast cast gear before casting a spell allowing the spell to complete quicker. However you wouldn't get the added ranged attack from it if you changed bodies, nor the accuracy of course.

So the real question is when does double-shot process? The moment you start the ranged attack or when the shot lands. Easy to test if you have augmented relic body just keep swapping it out and that 5% will surely show itself.
