Gall is unaffected by the Cavalry’s buffs on Alterac Pass.
When playing Alterac Pass against AI as Gall, I noticed that Gall was not getting the spell power buffs that the Cavalry normally give. Cho was affected normally and was doing extra damage, but Gall did not get the Cavalry Charge’s buffs and was doing regular damage.
Some people say the flat 10% applies only to AA and others say it gives 10% spell power. Either way it’s inconsistent.

This description makes it seem like it is a flat damage bonus. The Tempostorm article on Alterac Pass says it used to scale with level and is now fixed at 10%.
But according to reddit many heroes don’t benefit from it be it AA or spell damage, for example Baleog splash or Zagara’s Banelings.
I have noticed that it always buffs Auto Attack damage on every hero I’ve tried, though.
