When you Cascade, the heal happens when a player receives a bounce. When you Divine Star, the heal happens when the star touches a player on its route. When you Halo, the heal happens when the ring touches a player. None of these T90 talents provide all their healing in one burst at cast time.
Instead, there's an interim period between cast and heal (when the spell is "in transit").
In this time, do buffs gained/dropped effect T90 talents that are in-transit? Or are the spell "stats" decided at cast start time (or at cast end time)?
I'm also curious if haste effects the transit speed of any of these talents. (All T90 talents have some magical thing that moves at a certain speed, maybe they move faster with haste?)
Knowing the answers to these questions would be helpful in timing these spells.
P.S. I guess Prayer of Mending would also be under this umbrella of a spell that has a transit time of sorts. If you know anything about how buffs gained/dropped effect it, I'd be appreciative of hearing that too.
