So im Izzy and i love shen and i want to share this love with you through this guide. When i play draft pick/ranked i always play Shen Amumu or Skarner.This is my first guide on MOBA, and i hope you will like it. In this guide i will show you my way playing Shen The Eye of Twilight. Shen is my main champion and i really like him :)

About runes. I use those runes because i think they are the best.

Yellow : Greater Seal of Armor I use them and i think they are must have for almost all jungle champions. They help me at early game sustain, and early game survivability.

Red Greater Mark of Health I use them for Ki Strike bonus damage, for survivability when ganking mid, so the AP can't burst me down so easy.

Glyphs Greater Glyph of Magic Resist I use mr glyphs for early game magic resist so the lanes where are some ap's don't deal so big damage to me.

Quintessence Greater Quintessence of Health I use them for bonus damage Ki Strike and for normal health bonus. I don't think they are best so you can change them with Greater Quintessence of Movement Speed(im buying those runes right now).

I use 0/21/9 masteries for early sustain and ganks. The most important masteries are Vigor , Tough Skin , Bladed Armor , then Swiftness and Runic Affinity .
I think this masteries are good and i recommend them to you.

About items, i start with Boots and 3 Health Potion, because i go gank at lvl 2 so i need that bonus movement speed. Then i buy hearth of gold for bonus health and gold per 10 second. After that i buy mercury treads or Ninja Tabi depending on enemy team comp. If they have many CC and ap's then buy mercury treads, and if they have many ad's buy Ninja Tabi. After that finish Randuin's Omen. I build that item beacuse of bonus health, health regen, armor, and very useful passive and active. When team fight is in progress active your Randuin's Omen. Then i buy Sunfire Aegis for bonus health and armor, then Force of Nature for bonus speed and magic resist. Then i buy guardian's angel for armor and magic resist and for passive. And after all I buy Wit's End for bonus attack speed which is great due to your passive, and for bonus magic resist. This is all about my item build.

I think Shen is very durable champion, with many ways to absorb damage. His spells are very good, and useful.

His passive is Ki Strike

Ki Strike Every 8 seconds, Shen's next attack will deal bonus magic damage equal to 4 + (6 × level) + (10% of his bonus health). Whenever Shen hits an enemy unit with a basic attack, the cooldown is reduced by 1.5 seconds. Shen restores 10 / 20 / 30 energy when he Ki Strikes.
This is really good skill for big damage, and for energy regeneration.

His q is Vorpal Blade

Vorpal Blade Shen throws a sword at an enemy, dealing magic damage. The enemy is life-tapped for 5 seconds; allied champions that damage a life-tapped enemy are healed over 3 seconds, with the duration refreshed upon subsequent damaging. If Vorpal Blade kills a target, Shen is healed for 33% of the normal amount.
THIS is really good skill for harassing.

His w is Feint

Feint Shen is shielded for up to 3 seconds or until it is destroyed. While Feint is active, Ki Strike's cooldown reduction on hit is doubled to 3 seconds.
This is really good skill for absorbing damage and for shielding at the end. I love when i go tower dive with teammate we kill enemy and my Feint saves me :)

His e is Shadow Dash

Shadow Dash

Shen dashes to a target location, dealing magic damage and taunting enemy champions he collides with. Shen gains 40 energy per enemy champion he collides with while dashing, and has 50% physical damage reduction from taunted targets.
This is really good CC, and for saving your teammates.

His ultimate is Stand United

Stand United Shen begins channeling for 3 seconds, immediately shielding an allied champion for up to 5 seconds or until it is destroyed. If the channel completes and the target is still alive, Shen teleports to the target's location.
This ultimate is one of most amazing ult's in game. It can save your teammate around map, you can ult to help gank or just to help your teammate killing an enemy.

About summoner spells I use Flash and Smite. Flash is good for running, and chasing enemy's.
You can change flash with Ghost or Exhaust depending what your team needs.

Pros:
Very good ganking due to Shadow Dash
Very secure and good jungle with Feint and Vorpal Blade
Very good damage absorb with Feint, which can save you from deadly damage, and some ults Hemoplague, Requiem, finales funkeln
Can save an ally in trouble with Stand United, and can turn tides of battle in your profit
Cons
Easily counter jungled
Not so fast jungle

Start with boots and 3 health pots. Start ad red and get a pull, at lvl 2 lvl Shadow Dash, and go gank top/mid/bot. When you ganking ping your allies and say them you coming. If lane is pushed go gank. Start the gank and head over the enemy if they are close to your allies or your side of lane. Shadow Dash in them, and try to taunt them both while your allies are attacking them. Spam your Vorpal Blade so you have enough energy for another Shadow Dash, and because of your taunt and slow from red buff you shall be able to kill them. If they Flash its successfully gank. When gank is over continue your jungle with clearing the whole jungle and then going back or looking for another gank( i always go for another gank is there is an chance). When you hit lvl 6 level up your ult and always look around map if your allies are in trouble. If an Allie is in trouble Stand United him. If he isn't so low at HP you can try to back. Shadow Dash enemy and wait your allie help you. If he is wounded and needs to go back hold a lane for him until he comes back.

At start of teamfight ult to your ad carry, and Shadow Dash in their team, activating your Randuin's Omen. While they are taunted try to focus they AP/AD carry and spam your Feintand your Vorpal Bladeas much you can. Say your teammates they can bait enemy's so you ult to them. ALWAYS BUT ALWAYS look around map if your allies are in trouble. You have to start teamfight with your Shadow Dash and you have to protect your ad/ap carry. If the enemy's are chasing you and they are getting closer to your team(if ad/ap carry is alive) dash into them to save your teammates.

Whenever you see and chance to farm an lane go for it because you need money. Last hit with your auto attack and with vorpal blade. DON'T BE ANGRY IF YOUR TEAMMATES ARE KSING YOU BECAUSE YOU DON'T NEED KILLS BE HAPPY WITH ASSIST AND SAVING YOUR TEAMMATES :)
