Tristana "E" does some damage the moment it hits
I just played a game as Tristana and I noticed that a little number 2 popped up when I hit and enemy, when I tested it later on on a minion, it lowered the minion's health by 2 and when I checked the stats of that minion with left clicking it, I noticed that it only had 318/320 hp. This isn't game breaking but someone might be unlucky enough to die with the extra 2 damage added.
