Azir Passive can be used on Summoners Pool and never die.
Was just playing a bot game for FWoTD and picked Azir. I was using his skin aswell and had a Yorick, Lissandra, Garen, and Ashe with me. It was some time into the game and I noticed that Azir's passive was on the Summoners pool where the lazer comes from. So I clicked it and his Passive spawned. I got a tower in the Pool that was always gaining HP and would never die. My passive never went on cooldown either but I could not use it on any turrets. Just reporting this bug as a miss-click could completely ruin an Azirs day.
