So after the recent nerf of irelia I wanted to mess around and find a new build. I was playing and came up with this build sort of as a joke and discovered that it kind of made me impossible to kill. She ends up with 104% attack speed and 100% life steal while managing to build a reasonable amount of both attack and AP so all of her abilities will do a sizable amount of damage. The summoner spells are used primarily for escape in sticky situation where your opponents have too much CC at their disposal. If you play this smart you really shouldnt die and you should be a terror through the game. The biggest weakness this has however is if they get a lot of armor your gonna hav a problem a thornmail can be a large thorn in your side. The best thing you can do is stay alert to what they are building and pick on the softer opponents. remember your an assasin so get your kill and get out. If you can stay alive early game and get a few kills you should pull ahead of your opponents for some large midgame advantages. Late game pick at mages and squishies and avoid sustained combat with durable opponents.
