This guide is for you joining a match in Proving Grounds going All Random All Mid. No time to figure out what items Udyr needs? I'll keep this short and sweet.

Looking at the build, there is a lot of wiggle room for changes Focusing on Health and Damage.

1. Starting items: Rush Philosopher's Stone + Heart of Gold = Earliest GP5 possible is best.
2. Shoe selection: Mercury's Treads vs. AP/CC OR Ninja Tabi vs. AD
3. Early Durability and Damage: Phage + Wit's End
4. Building Power and Mobility: Trinity Force
5. Pumping some Health and CDR: Upgrade Philosopher's Stone => Shurelya's Battlesong
6. Finally, more power and resistance: Atma's Impaler vs. AD / Maw of Malmortius
7. Personal Preference:
   • Randuin's Omen = Tons of Armor, Health, HP Regen. Adds Minor cool-down and allows for better chasing when paired with Shurelya's Battlesong and Blazing Stampede
   • Banshee's Veil = Great against annoying Burst AP team, huge Magic Resistance
   • Force of Nature = Even greater Magic Resistance + Health regeneration will be decent for those stand-offs; definitely a great pick.

Follow-up with your team, Udyr is not the best initiator. Best way to destroy a surrounded enemy is sequencing,

Blazing Stampede> Wilding Claw(For the proc)> Iron Mantle for retaliation or absorb incoming enemy team damage.

Cycle this for another stun or chase.

Ghost Heal Flash Barrier Ignite

This choice depends on allies, enemies and comfort level

I like to start with 2 in Iron Mantle to absorb pokes as much as possible and 1 in Blazing Stampede for early stunning utility.

I feel Wingborne Storm just doesn't work as well as expected, getting surrounded between enemy champs = bad idea!

Which to max first?
Taking hard pokes? Max Iron Mantle
Getting easy over-extenders? Max Wilding Claw
Providing the CC for your team? Max Blazing Stampede

Your own preference.

That's all there is to it, please provide feedback and don't forget to vote.
