The FNAFDyr requires faith and soul to play. If you put your mind into it the whole game would be a breeze. You can jumpscare every champ on the roster from any corner and because Udyr is a slippery mf he can get away with it. For the loadout you want to be agressive and be as annoying as possible. There are two rune pages here for the specialty because you can run the old-fashioned fast runes or be innovative and go tanky as hell. The choice is yours.

Gameplay
The last section is the gameplay. FNAFDyr is a very precise game style for the new reworked Udyr. This build is purely for fun and you can get creative with this shananigans. Your main goal is to STUN the fuck out of the enemy team and slow them to the point they are crying you a river in all chat. No matter if you int hard or lead greatly you will be the CORE of the team.
For all the gaming experience you should go and listen to that song while you play I really recommend it.
