Hello, my name is Etsu. I have played hundreds perhaps millions of udyr games. Recently I was testing out a build based on highly calculated numbers and I am here to post my awesome findings.

For runes I run a standard AD rune page because AD makes your autos hit harder. Also I start tiger stance so it is easy to take down buffs np.

This is where my calculations come in. I have found the most cost efficient items to buy as well as the highest dps output and tankability.

Item order:
Boots-Doran's Blade-Manamune-Sorcerer shoes-Shurelia-Locket of Solari

-You start boots so you can move fast
-Get dorans cause it helps jungle, but only buy one cause repeats are for ***s
-Manamune is the most cost efficient item and it will help jungle speed because you can stance dance
-Sorcerer shoes gives you magic penetration for your tiger stance as well increase healing from turtle and later dps from phoenix
-Shurelia is the next item which will give CD for more dancing and the speed activation so you can dash and stun for an easy catch
-Locket is the next item giving you health and a team shield because you already do so much dps that you need to provide support to your teammates now as the game progresses

Max Q then W then E then R

Q-E-Q-W is the initial first 4 levels

Summoner spells are smite for obvious reasons and flash cause flash stun is flipping overpowered.

Conclusion is this build is worth trying and it is flawless. The only problem is that those items would fit 56 better than 46 and only a few people would understand that. GL and enjoy your free wins
