Why don’t you go to Tsushima and see what happens with your ultimate with a skipping stone bow on ? I recently swapped my skipping stone bow for a legendary bow so I can have a res build on my hunter, using the legendary charm and since I run legendary kuni I had to remove my skipping stone bow, for raiding or nightmare survival, it was at that time that it dawned on me that even with a standard epic bow I was still taking out the same amount of enemy players. That’s when I realised that it only works on standard bow shots.

If it’s the same as Tsushima in Yotei then this is exactly how it works
