The purpose of this build is to test the new Shen rework in the Jungle with two Viable builds. The first is focus on a damage early to mid game using Devourer enchant. The second is primarily tank with a bit of damage from titanic Hydra.

Standard 9 armor seals for the Jungle
Some cool down runes because who doesn't love some CDR
Attack Damage to clear that fat Jungle
Some attack Speed to clear fast early

0/12/18 for some tankyness and to get that Grasp of the Undying healing for the tank late game or you can go 0/18/12 for some quick burst early game to make your ganks just a tad stronger

Items can varying depending on your team comp if you already have a tank like a Braum support and a poppy top lane you could go Devourer, if you do not have a strong frontline you might want to go Cinder-hulk.
Titanic Hydra- This item gives +500 Health, and 50 Attack Damage, this item's passive deals additional damage in a cone shape, this is proc-ed with autos and Sated Devourer can also proc this
Ravenous Hydra- This item gives 75 Attack Damage, and %12 Life Steal, on hit it procs a AOE from the target and is also good paired up with Sated Devourer

Good Tank Items Include:
Spirit Visage
DeadMan's Plate
Banshee's Vail
Sterak's gage
Warmog's Armor
Locket of the Iron Solari
Damage Items if ahead:
Blade of the Ruined King
Guinsoo's Rageblade
Wit's End
Black Cleaver

Max Q first for jungle clearing, and damage
Max E Second for catching enemies out and starting fights
Max R as quickly as possible
Max W Third least useful

I hope this helps when Shen's rework drops, to jungle efficiently.... "The ever-watchful Eye is upon you."
Good luck and have fun!
