Not Updated For Current Season
This is the Shen build I ussually play and I get great success with it. Obviously you have to be smart on which order you buy the items depending on what your opponents lack in or have excess in. If they have no ability power character feel free to switch force of nature with a fire cape or another defensive/health related item. If you get all the items you will be virtually unstoppable. It is however hard to afford everything but the health regeneration you get from force of nature and warmog's armour you are set for late game already. There are also some characters that go really well with shen like kassadin or any stunners/slows because of shen's awesome taunt. I specifically mentioned kassadin because Shen can spam his abilities allowing kassidin to cast force pulse a lot. Force pulse plus taunt,vorpal blade and null sphere can dominate an enemy. If you have two casters in your lane, rushing negatron cloak can significantly reduce damage. That and feint can help you tank them. There is also another way of casting stand united on a friendly champ. You press r and then you press an F# button depending on who you want to cast it on. It is also important to note that F2 is for the first champ then F3 and so on. For example, say you want to cast it on your buddy who's a team fight and it would be hard to click on him using the map. You see where he is on your list and if he's fourth you press F5. You should always be looking at te map for opportunities to use it either to help a friend, push a turret or back door. Yes i said back door. if you have a stealth character like eve or twitch, or if you have a twisted fate you can easily back door with them. This is also handy if twitch or tf needs you to tank a turret for them. If you think i should add more here or think i should clarify my item/rune/masteries choices feel free to comment.
