I have found Sion Support to be very broken. There are many ways to build this and its support is fun. Tank is the main one is use and its very fun. You can almost never die and do a fair bit of damage. There is also Lethality or "AD Sion" which is also very fun. You are not as tanky but can destroy the backline people in seasoned. Full AP is one of the weaker Sion build but it's very stupid and powerful. I hope you enjoy playing this as much as I did.


Laning phase
You play Both Tank and Lethality Somewhat similar but there are a few
differences. With the full tank build, you are going for hits with your
Decimating Smash(Q) at level 1 and throughout the landing phase. After that,
you so play it the same but with more damage and a slow to hit it easier. At level
6 you want to charge your ultimate at turret so they don't see where it's coming
from. Lethality works the same but you don't tank for your ADC you deal all the
damage.

Full AP
When you go full AP you want to poke out the enemy ADC with your [[ROAR OF THE
SLAYER]](E). Before you first back you don't deal a lot of damage but it still
hurts the other ADC. When you use this try not to mess up your ADC's farm. Go for
Caster Minion and please don't steal their cannons.


Abilites Order [Full Tank/Lethality]
Abilites Order [Full AP]

Abilities
1. Decimating Smash
This is your main CC through laning phase. The damage from this when going full
lethality is insane. They can not see the outline of it if you are in a bush.
2. Soul Furnace
This is a very good Ability but its passive is the best. When you kill something
like a minion you gain permanent HP. You are not farming late game, so just steal
the raptors or something.
3. Roar of the Slayer
This is used to hit your CC because the slow this gives is very good. When going
full AP this is the majority of your damage and is very powerful.
4. Unstoppable Onslaught
This is a Gaint CC that deals a lot of damage. With this, you can start Fight or
run away from ganks because you become UNSTOPPABLE.


Roaming
You can have an insane roam potential with your Unstoppable Onslaught(R). Try to use it so they can't run away but not too close to where they can dodge it easily. One thing that you can do if you are going full AP or full lethality is going into the enemy jungle and go into a bush to one-shot them. Make sure you can one-shot them or getaway at least.


Team Fighting
You play this two ways depending on which of the three builds you went. If you went full tank you need to tank all the damage and deal your damage as well. Try to keep your carry safe and don't let anyone near them. When going full AP and full Lethality you are going for the one-shot combo's. Try to break their backline and make their ADC go on suicide watch.


In Conclusion
This is a fun role for Sion To go and has many builds to go with it. You can go a Gaint Warlord who will Never die or a Mass murderer. There is a lot of fo fun with this.If you liked it or have any opinions leave a comment.
