Hello! This is my first guide to Sona, so uh, I hope you enjoy! :)

I put much work into this, and it would be nice to give me some suggestions so I can make it even better. Also, so I can make my future guides much better to learn off.

The reason why I choose to build head-on aura is mainly because:

She has many aura passives

She has an OP healing skill

When close to finishing build, VERY tanky with health

Crescendo initiates fights very effectively

Made to support like a boss

Pro's

Crescendo initiates fights very well

Wins teamfights often due to various auras

Makes your ADC very sustainable

Not as squishy/A bit tanky

Very fun!

Con's

May get boring after a while

Must initiate at the perfect moment

May cause the lost of a game if you KS the ADC

Runs out of mana quickly early game

Usually gets targeted first in teamfights

The reason why I chose Exhaust is mainly because.. well.. you're a support. A support with a healing skill. So, that means you don't need to replace a useful summoner spell for Heal. Also, everyone on your team most likely has Ignite and Flash, or the person in mid has Clarity or Teleport, and obviously your jungler has Smite. And Flash is self-explanatory.

I chose Greater Glyph of Armor and Greater Mark of Armor mainly because:

-Makes you tanky
-More chance of surviving teamfights
-Can retreat successfully
-Survive easily early game

And for Greater Seal of Gold and Greater Quintessence of Gold, well, obviously for gold because you're not supposed to lasthit your ADC's minions.

The items, you can replace a Sight Ward for a Vision Ward instead, if the other team has a stealth/assassin jungler.

Also, you may buy a Guardian Angel instead of a Frozen Heart if you usually die a lot in a teamfight and your team is still alive with 1/2+ HP left.

If your team is losing teamfights, and your ADC is getting targeted first, then you can also replace Frozen Heart with Zeke's Herald.

You can also buy a Mobility Boots instead of Mercury's Treads or Ninja Tabi if your team pushed really hard early game, or viceversa, to get into the teamfights quicker to aid them.

Usually in early game, I just spam heal every time my ADC is one full bar or more low, and I harass with Q. Never use E unless you're chasing someone, or retreating.

In a teamfight, you should always stay in the midst of your allies, and when your tank (or CC) uses their ulti, you use yours right after it finishes, and then spam heal and Q. If they start running away or your team needs to retreat, use E and use Shurelya's Battlesong. If your teammates are being chased and they cannot run away, use Locket of the Iron Solari, and spam Q, heal, and E.

Don't lasthit any minions unless you have the lane to yourself (ADC died, ADC recalled, etc.), or it's late game and everybody's farmed, because when teamfights start to happen, you need most of the money to get all your buffs and auras.

You don't need to worry about leveling up, too, because as long as you're a good support and you get many assists, that will be your source.

Send me pictures of your winning stats and games and I'll post them here!
