For example if you cast a slow spell (maybe a slow projectile like Ball lightning or Ice Nova thst slowly repeats on Frostbolt) while stationary with Ralakesh, then start walking before it hits the enemy
Does the spell retain the bonuses from all the power/frenzy charges you had when you cast it?
External link →Skills generally do still snapshot their damage throughout all of their hits that aren't considered separate casts, which is why exerts even function. The fuzzy rule is that if the crit roll would apply to all hits then any applicable stats would too
That is not true.
If i cast Ice Nova on Frostbolt with Alternating Sceptre equipped, then weapon swap quickly
Does the Ice Nova inflict Chill or Brittle?
Chill, if you swapped before the nova reached a specific target. Non-damaging ailments aren't determined until a hit is applied.
What if i swap between repeats of the same cast, will it inflict brittle and chill over the single ice nova cast?
Is that intended, hence the “Altenating” part of the item’s name?

Yes.

It's not specifically intended, just a natural consequence of how things work.
That being said I know for a fact that there are some exceptions. Vall Lightning Strike will snap shot any damage buffs from the moment it is cast.
No, it won't
