Ok guys, before you bash on me, this is the way I play sona, it might or might not work for everyone. So don't comment saying "Omg I can't play this way this guide sucks" It all comes with practice. Noone is good with a specific build at the start

Hey guys, my name is Speardark and I'm a support player. Support is my main role and I am bringing my way of playing Sona here for you guys. I will be updating the guide in the future to improve the grammar(since english isn't my first language) and to improve the quality of the overall guide

Pros

Can be tanky
Great Support
Has buffs to ad and stats
has a stun
Plays an instrument

Cons

Slow early game
Semi-Squishy
Gets banned alot(from my experience)
Easily countered

I use more defensive runes which allows for me to tank enemies for a longer period of time. You could switch the reds for magic pen or attack damage for more poke. You could swap the yellows for gp10 runes. You could even swap the blues for cdr. But I recommend the runes I have listed if you want to be able to tank an enemy team at the start.

I use the 1/8/21 masteries for a standard support champ. you can do a 1/21/8 mastery tree if you wish to be even more tanky though. I mainly went into the utility tree to grab the gp10 with extra xp. Went into the Offensive tree just to pick up Summoners Wrath for the exhaust buff.

The items I have listed aren't in any particular order, you mainly build items depending on how you need to build them, but I prefer to build into the philly stone first for sustain in the lane. I build the HoG second for the extra hp and the pick last. The items you can grab in any order near the end though. Just keep grabbing vision wards everytime you back though.

I generally max my Q first if I'm winning the lane. If you're having problems controlling the lane, max your W first. The bonuses to maxing Q over W would be too give your AD a boost to their ad which is good. The bonuses to maxing the W first would to be getting greater heals and have increased resistances.

Exhaust: One of the strongest spells for a support, can be used defensively to save yourself or a teammate.
Flash: Why wouldn't you want this? It is a good escape mechanism.
Clairvoyance: I would only grab this if your AD wants to grab exhaust instead of heal.
Anything else: I wouldn't grab anything else mainly because they dont really affect me too much.

You really just want to keep your carry alive and help him poke, but make sure not to KS or take his cs haha. Keep the river warded and but wards nonstop( I usually have a fullstack of wards everytime I leave base.) Try to stay in lane as long as possible, keep dragon and baron warded, ward entrances to their jungles, your jungles and deep inside of their jungles.

You really only farm to keep the enemy minions off your tower, or when your ad if out of lane for various reasons. Other than that you don't farm until late game to help your own team push

Time your ultimate in teamfights and pop your items/auras in response to help your team win team fights.

Pick up your Q at level one, level two grab your heal. At level 3, grab either the heal or your Q according to how your lane is going. At level four, grab your E. Then max your W or Q depending on which you grabbed at level 3. Leveling the Q gives ad/ap modifiers which can help when trading with the enemy. Maxing the W first gives sustain in lane and gives the ability to heal after a trade. Use your E to get into fights faster and your R when you can hit more then two people at one time.

This is the way I play sona and it has brought me much success. Leave any comments on with any tips you might have and I will try them out. Leave feedback guys and tell me if the guide has helped you :)
