Braum's Passive
So I was playing Nautilus in the jungle and our support was a Braum, and when i went for a gank at bot lane, the enemy tristana had Braum's passive on her. I used my "W" and AA Tristana, but it didnt prock with Braum's passive so she would be stuned.. Happened 2 or 3 times that game, but I think its only when Nautilus "W" is activated.
