Hey, I'm a fairly new league of legends player (started start of season 11). At the start I literally hated league of legends so much and never wanted to play but the friend that got me into it said there was a champion where you could literally go afk and still be playing, and so I bought Yuumi.

Eventually I began to actually enjoy the game and became a jungle main for a short time before returning to support. Eventually I got bored of support and thanks had the idea to make Seraphine (someone I was playing a decent amount of at the time) a jungler for fun. Naturally the logical progression from this is yuumi jungle and a friend was inspired by Luminum's movespeed soraka build and gave me the idea of movespeed yuumi jungle, so here we are.

I'm not saying to not play it in ranked, but I'm also saying I most definatley have never brought it into ranked...

Why the hell not? I find just the concept of yuumi going predator funny so predator yuumi jungle? sign me up. But besides that I made a pros and cons list because I want to make this a full guide LMAO

Pros:
+ amazing roaming around all the map
+ so fast a lot of the time the enemy can't even see your ganks coming
+ effectively lets your team have two supports, making all your carries that much stronger, since they can also farm your camps with less punishment
+ fun being so fast and funny to see

Cons:
- VERY easy to invade + kill
- slow (and usually) unhealthy clear
- can be hard to actually make work
- can feel useless if you don't get early lead / snowball
- can very easily tilt people

ok now HERE's the fun part...

you will usually want to do red buff > blue buff > gromp > gank, YOU MUST DO RED BUFF FIRST OTHERWISE YOU WILL DIE TO GROMP. If you really want to gank the other lane first though, you can skip gromp so that you can start on your blue side, since yuumi doesn't have much of a level 3 powerspike since you start the game with a point in your w.

This makes yuumi generally stronger on blue side since you can get your bot lane to leash red buff for you, which is faster than just your top laner leashing.

After your double buff gromp you will want to look for a gank. Its usually easier to gank top since the 2v1 is stronger than the 3v2, so if your top laner is pushed under their tower, this is perfect. Coming from river, you will usually hop on your laner, use q to slow them, and then exhaust them whilst buffing up your laner to run them down for an easy first blood. The same concept applies in bot lane.

POST 6 HOWEVER, IS WHERE THE FUN COMES IN
when your ult is up and you see a lane you want to gank, you can activate your predator, speed yourself with e, and if you took it/have it already, activate your shurelyas and ult as you come in the lane. This will usually be very surprising for the laner since they don't expect a yuumi coming in at mach 10 speed with a book that shoots lasers.
