In a few games, I have been able to finish this build and it worked beautifully. The other team feared me and retreated when I was present. In most games I lurk around the jungle and feed on whomever approaches. Once, my team pushed to the enemy's base but died when ganked by the other team in their base. They all pushed back but I was lurking in the jungle and popped out of nowhere and slayed them all because of leap for surprise and stun for escape if need be. Right when the other team starts to hit, I initiate my Ult. to increase my mag. resist. by a little, but with no need. Because I am already too OP.

The first item to buy is Doran's Sheild which gives you HP, HP regen, and armor. I would get boots next then a Sheen. After that I purchase a frozen mallet and phantom dancer. I would recommend hextech gunblade for spell vamp and life steal. Sell doran's sheild and get a madreds to take down tanks easier. Lastly, purchase a trinity force from sheen

As you can see, this build gives Jax attack speed, running speed, slow abilities, life steal, spell vamp, hp, ap, ad, and some dodge to aide counterstrike. With this build, I was able to go 5v1 because of counterstrike, empower, and his Ult. If you are chasing someone, leap with empower already on to deal maximum damage. Once you have your target, frozen mallet will continually slow the target and allow you to attack continuously. When you save your teammates, jump in the middle of the enemy team and stun them when you get E available. Leap out if you please or stay and kill them all. Tank a tower if you please, but run away if you see the other team, this build does not allow you to stay and take tower hits and other champion hits.
