Zarya's weapon causes more damage the more damage you absorb with her abilities. However, the damage slowly goes down over time.
Lets say you fire a grenade when your energy is at 50, but when the projectile actually hits, your energy is at 45. How much damage does this projectile actually cause? Will it cause the damage of the energy it was at when it was shot (50) or the damage of the energy you have when it hits (45)?
I mainly ask this because of Mercy's damage beam, which is only active when the shooter is damage boosted when the projectile hits, not when it's shot (so you'd have to keep your damage beam on the Pharah when the rocket hits).
Does it work the same for Zarya? If it does, how does it work when it's deflected by Genji?
