Threats to Sion with this build
Welcome in my first guide ! Don't like supporting ? Think it's can't be fun ? Try to supp with Sion ! Trust me. I'm not very good player, but Sion is one of my mains, and with 5 maestry level i know what im talking about.
Pros / Cons
2 stuns & slow
Long range damage with E
If your team needs it, you can change you build and play like normal offtank/tank
"Sion supp !? WTF ?" effect guaranteed...
... But not all of your teammates like it
At early game, you have only Q to stun
Long casting Q
Hard to use R good
First about runes. Do what you want. All TANK runes is good for this build. AD runes is ok too, for more Q and ult damage.
Tank, support, cooldowns is key words. In build i show you my, but you can do your own. Only remember, TANK,SUPPORT,COOLDOWNS.
Remeber. You starting all teamfights. All damage is on you. Start with R, try to stun a lot of enemies, than use your Q to stun them for a long time. If you stun it 2 times (R,Q) for max time, and your teammates is not idiots, teamfight is yours. For better effect you can launch W, before R, but remember not to steal kills with using it.
Kill Big mininons, attack from long range with E. Rest the same like in teamfights.
Q - You can chose a time of casting it, if you hold button longer, it's hit stronger and stunning, but enemy has got more time to run away from range of ability. You MUST learn how long hold Q to make the best reasults.
W - Nothing special. Just a shield on you. Absorbing damage, and dealing it when you use it second time, but you must wait few seconds to next use.
E - Slowing, attacking from distance skill. Just see in 18 second: https://www.youtube.com/watch?v=BS9aTrNquek
Kill big minions with Relic Shield passive. The same with normal minions, but only when you want heal your teammates. In late game, just kill minions with Q, and E.
