I started using Sion about a month or two ago and found he really came natural to me to control. I began by using the AP Crit Tank Build for Sion on here, but found it was really inefficient early in the game. This is a build I am still in the making in, but with it, my most recent k/d ratio was 21 - 10 - 19. The one before that was 15 - 3 - 7. And the one before that was 13 - 5 - 4. As I got used to the build, it became easier. The thing I love about my build is its adaptability.

(PS: Third time is a charm - _ - . It is listed on the unknown creator list twice because the site registered me offline for some reason - _ -)

First Thing, buy the berserk boots. Sion (from my experience) is not a very good solo player until about midway through the game. So try to find a long range player and lane with them (preferrably Ryze). Don't go into the towers and if you get a chance to gang up on one guy with your stun and partner, do it, but make sure you don't go into enemy lines. Depending on if you are getting many minion kills or regular kills, you may need the Averice Blade to help. It helps getting an extra 5 gold every 5 seconds. You can get it either way to get your build quicker, or you can continue to just getting the Tear of The Goddess. I chose that item instead of the rods because of its mana recovery skills, and the stacks of 1000 mana added onto your stats.

This is where what you do may decide whether or not you can finish your build by the end of the match. You have the Zeal by now (I usually get pieces for it here and there with leftover money earlier than this). Get the Phantom Dancer ASAP! Depending on whether there are a bunch of enemy minions lining up on your side, or theirs will be what chooses what you get first. If they are lining up on your doorstep, get Taimat. If not, finish the Phantom Dancer, and then get Taimat. As soon as you get Taimat, you will not have to worry about any of the minions anymore. They will just be feeding you cash now and take a few seconds to kill a group. By the time you get this, save up for the B. F. Sword. Once you got this, you should be near end game.

Now you are able to just feed off of the minions, take the dragon down by yourself, and kill most enemies (with assistance). The only thing you need now is your infinite edge. You will notice with it that you can most likely kill most if not all of their team now, and destroy towers like there's no tomorrow (espescially with your ulti :D). If there is enough time, and you feel like making the other team cry out things like, "Your Sion was fed" or "You guys are cheating. fake!!!" then continue to replace your "money sword" with another infinity edge. This ending has been tested, and works very well. But I have been thinking about testing the last item with something else. So if you adventurous enough, try changing bits and pieces of this guide. It is very flexible, and it is a guide, not a rulebook on how you are supposed to exactly play. Hope this helps for an amazing Sion. More updates soon for this build ^^.
