On damage modifiers, such as the Kog'Maw's Bio-Arcane Barrage or Kayle's Righteous Fury can the damage given by AP/AD be changed mid-effect? For example:
Say I'm playing Kayle and I have 100 AP. I trigger Righteous Fury which does 60 plus an additional 40 damage from my AP. I had Guinsoo's Rageblade and attacked someone 4 times causing my AP to go up 20. Righteous Fury is still in affect, so will the next attack with it have that extra 20 AP applied to it?
Basically, if I trigger a damage modifier ability, will any respective damage buffs (AP/AD), given mid-ability, affect the damage bonus from said ability?
Will it happen for DoT effects (poisons, Malzahar's Malefic Visions, etc.) and/or channels (Supresses, Kat's Ultimate, Fiddle's Drain, etc.) as well?
P.S. This is even written confusingly for me, I'd appreciate if someone could edit it to make it sound more logical.
