Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
My first Build
Summoner Skills : HEAL - IGNITE
Doran's Shield - For armor ,health and HP regen
Mercury's Treads - for Movement speed and magic resist
Randuin's Omen - VERY GOOD ITEM FOR SHEN , He gives you 300 Health | 90 Armor and 25 Health Regen per 5 sec. His Activate is too good he slows M speed and A speed to target by 35% for 2 sec. + 0.5 seconds for each 100 Armor and Magic Resist.
The Black Cleaver - +75 Attack Damage and His Passive is : Physical attacks reduce your target's Armor by 12 for 5 seconds, (maximum 5 stacks).
Atma's Impaler - I take this item for Armor and his Passive : Physical attacks deal an additional 2% of your max Health in damage.
And Aegis of the Legion - +270 Health +18 Armor +24 Magic Resist. This item is very good because he have Aura effect.
