Hello and welcome,
i'm la Schoull, french player since 5 or 6 years, reach plat season 6.
I want to share my Xp on SONA as a support.

Bienvenue,
je m'appelle La Schoull, je joue à league depuis bientot 6 ans et je voudrais partager mon expérience sur mon support préféré, sona.

L'idée de ce build est de rapidement obtenir un ROA, qui permettra de spammer les sorts, dégâts et soins, de devenir plus tanky, tout ce que sona a besoin.
En teamfight Rester derrière, punissez les carrys mal placés par un ulti-Q-auto-ignite et protégez vos carry avec vos AOE de soin, bouclier, dégâts et buff de mouvement.
Vous ne pouvez pas gagner seul, protégez les carry !

This build's purpose is to quickly build the ROA to spam spells, become tanky and more difficult to kill.
During teamfight, stay behind the frontlane, punish the ennemy carrys by a good ulti -Q - Auto-Ignite and always protect your carrys with all the nice AOE you have (shield-heal-mouvement-dmg).
You can't win alone, protect your carrys.

Pas grand chose à dire, prenez le patern défense pour contrer l'early difficile de sona et améliorer les soins.

Take the resolve tree to be more solid in early, expetially in laning phase. (Heal buff is also very very good)

Spellthief's Edge
Needed item, use your Q to easly reward gold. Your first objective is to quicly reach the 500 gold earned to have free wards !

Frostfang
Upgrade the support item for more gold income and mana regen.
If the first back you take is more than 1100 gold, take Catalyst of Aeons instead.
I don't take the Remnant of the Watchers since the 3 wards are Ok. Take Control Ward and Oracle Lens as soon as your Frostfang is upgrade !

Catalyst of Aeons
Depends of the back and gold you make. Priorize the Rod of Ages as soon as possible in the game.

Rod of Ages
All you need to spam spells and get more tanky. Core

Athene's Unholy Grail
The second item you need. Heal and mana regen. Maximaze the heal incomes by poking as soon as possible. The little RM helps against AP supp.

Ardent Censer
This item is a realy good choice, you can apply it easly because of your AOE shield, one heal (w) and everybody gets the shield and the ardent censer buff ! cool ! Buff also ypur shield and heal !

Redemption
Buy this item only if your team needs more heal to counter a big AOE damgage like brand's or sthing like that. Buff the heal and shield too.

Shurelya's Battlesong
This item is realy good if your team needs positionning fast or engage (vs poke comp).
CDR and health helps a lot too.

Rabadon's Deathcap
My last item, must have to reach 700 Ap, heal and poke a lot. Ap is realy good on Sona only if you can survive during the fight.


Second choice item:

Zhonya's Hourglass
Take Zozo if you are always focus by assassin in TF


Lich Bane
Very good to poke more. Speed and mana helps. But if you take ROA, you dont need it.

Seraph's Embrace
Take Tear of the Goddess at your first back to start stacking it.
The shield and mana helps. You don't need it if you take ROA.

Rylai's Crystal Scepter
Slow applies on only 2 unts (2 for Q), not very good on sona. Health and AP helps.

Spellbinder
Good choice but raba is a better choice

Twin Shadows
Combined with Shurelya's Battlesong to catch leavers ^^

Void Staff
You are the only AP champ in comp, and they build full armor. Why not.

Morellonomicon
Vs mundo or Ww ? maybe ...

Mejai's Soulstealer
If you are very very ahead.

Hextech Rocketbelt
Need to reach carry for a perfect ult ?

Everfrost
Good for mana and active if the ADC needs a good protection.

Banshee's Veil
Alaways destroyed by an AP assassin ? Why not !

Abyssal Mask
Your team damage is AP and nobody takes it ? Why not !

Locket of the Iron Solari
Protect your team.



BOOTS CHOICE :

Mobility Boots or Boots of Swiftness for MS
Ionian Boots of Lucidity if you don't plan to reach 40% CDR with your build.
Mercury's Treads For Ap and CC Composition
Ninja Tabi For Ad and AutoA composition
Sorcerer's Shoes Best choice to deal more Dmg

The only difficult thing to master is the passive.
La seule chose difficile à maitriser c'est le passif.

You need to be realy focus on your passive, it's all the différence.
Slow,damage or exhaust, it's your choice. Be focused on what is the best choice.

Surveillez bien votre passif, c'est la différence entre une bonne et une mauvaise sona.
Combinez vos sort dans un certain sens avant une auto attaque, en fonction de l'action:
Gank QWE autoA pour ralentir
Défense EQW autoA pour un mini exhaust
Attaque EWQ autoA pour max les dégats
(Cela marche si vous n'avez pas de stack de passif avant l'action, à adapter en fonction)

Pros
+ Good sustain/harass in lane
+ Great against poke compositions
+ Capability of dealing decent damage later
+ AoE stun for teamfights


Cons
- Quite squishy before ROA
- Mid game could be difficult vs Assasin
