Hello,
Iam a Master Yi main and today do i want to show you my way for the patch 5.23 .

Devourer
If you take Devourer(I highly recemmend it) you have to Farm alot. By the Way never do the Herald/Drake before you have devourer ready the Herald/Dragon s giving you 5 stacks what is a insane boost to farm your stacks. For each Jungle Camp you have finished you get 1 stack btw you can give you midlaner the Blue-Buff if you want you will get a Stack also if ou dont lasthit it. You can have up to 30 Stacks on Devourer then do you get the Sated Devourer.

I would recommend you to start always at botside.
BLUE TEAM:
Start with Krugs and smite it early, bt if you have a adc like twitch i would recommend you to smite late because of the dot it could happen that he gets the krug and that would put you hard back. As the secound one pick up he Red-Buff and set a ward into the bush to take care of invades. As third one Take the Blue-Buff u can smite that one too and after that u will get lvl 3 if you are on low hp go for the w on lvl 3 and if not go for the q again. That means low after Blue = w on lvl 3 and q on lvl 4 and if you arent so low go for the q on lvl 3 and the w on lvl 4. After Blue try to gak top if you cant go for the crab and try to gank mid. After ganking mid (if you could or not) go back to the jungle to farm your jungle. With Master Yi you are going to farm a lot on the first 20 minutes because then should you have your Sated Devourer.

REDSIDE:
On Redside its the same but you are starting also from botside.
At First do you do the gromp, then the Blue-Buff, the Red-Buff..... Just like in Blue side
