So i was looking through the LoL image folder...

I noticed some weird things... For one, all of lee sin's abilies are labled with the name "BlindMonk" And ashe has an unused image labled "crazydance" Xin zhao's pictures are labled xenzhao, and then they have xinzhao copies... so they have double the images... There's a fully completed unused champion labled "water wizard" He's even got a sound file, but it's undecipherable.... In the champion image folder there's an unused mundo skin that's a recolor with him green.... maybe unused, maybe retired... There's a UK fiddlesicks skin All urf content has been wiped from the files... I found something big now... There's a file in "championscreens" caleld vizobscure It resembles nothing in game... it's a black hooded wizard with a triangle on his head... none of the other files have anything refrencing him..

There's a teemo rune in the rune files... In the data files the champion prices are in tiers Ex:

Edit: found another unused champ. His name is averdrian and he seems to be finished, and he looks alien like. There's a unused file called "bantamSting_temp which is a child's drawing of a wizard hat that is sleeping on top of a stick. I also found a image of a old singed passive labled "chemicalman_burnresistance" There's another child's drawing labled "fear" which is a interpertation of "the scream" Amumu's image names are amazing. His ult is caled "bandaidthingy" his Q is called "bandageflighter" there's an alternate W called "disgustingsneeze" There's an alternate teemo passive in which he would turn into a... "mechnobot". I wish that was a joke. he actually has 3 alternate passives. The mechnobot, a "sharpshooter" (which probably lowered enemy's dodge stat before the dodge was removed) and eagle-eye. He also has a alternate R, called tactical-strike... which i kid you not, is a nuke.

Alright i found what i was looking for. Water wizard abilities. He's got 2 different passives. one is called soothing aura, the other entrench. Torrent is his Q Typhoon is his E Vortex is his W And water elemental is his R. That's all i can gather from the image files.
