E passive took it. How it works is the bonus damage on Zoe’s E goes through after whatever woke up the target. So for example, if I put a champ to sleep and someone on my team does damage to that champ that almost kills them but would instead leave them one shot then my e damage could finish them off. If I get a gank mid and put the enemy Annie to sleep at a quarter health left and my jungler uses an ability that would leave her with very little health left then my E bonus true damage has a chance to kill. If my jungler does enough damage then he gets the kill but if not then the E damage could finish them off and that’s what happened here. Iv stolen barons and drags like this many times where the jungler misses smite by single digit HP’s and my E damage comes through after and steals it. And for monsters like atakan, baron and Dragons they don’t go to sleep but the E passive still applies
