I could be wrong but this is how I envisioned is:
(shoulder charge * greaves multiplier) + (shoulder charge * arc multiplier -original should charge damage) + (shoulder charge * brawler multiplier - original shoulder charge damage)
The reason I am subtracting the two shoulder charge base damages is because there is only one actual shoulder charge happening. The damage increases are stacked in accordance with their respective buffs. Again, I could be wrong.
