This is only for if you want to troll the living hell out of players.
I do not recommend using this build for competitive play.

I bought Rengar recently, so I want to try him out...
Game isn't going so well for me, I've been ganked numerous times, killed more than 5 times, and It's only the 15th minute of the game, we can say that I pretty much suck with Rengar.
But I didn't want to surrender, so what I did was build a 'Master Yi build' (Boots of Mobility and 5 Phantom Dancers) so when I ran around the map, no one was able to catch me, not even their Master Yi.
So what I did was, teleport to my Minions that have pushed lane to the Inhib turret and I took out the turret, but the enemy team was strong, so when I saw one I would pop my ulti and run like hell, recall and do the process over again.
I basically did that for 30minutes whilst dodging mulitple champoins by running into bushes and jumping back out on them to only run away in an instant.
My end game movement speed was around 700-800, I can't remember though. So I had A LOT of Move speed.


And when you're building All Phantom Dancers, just buy a Zeal first, then buy the Phantom Dancers itself once you've farmed enough money.

And once again, this is only for Trolling purposes, this is not effective at all in competitive play.

If you would like to add me on LoL my Summoner name is - Blendyy
(I'll be coming out with a videa soon on showcasing how effective this really is, so stay tuned :) )
