Why offensive sona? Well with this build you get amazing heals and amazing damage! Also, her ultimate does significant damage and is very good in teamfights.

This build is aimed for Ranked

This is my exact build in ranked games but I also use this build in normal games aswell.

-Passive- This spell is what can make or break a becoming a skilled sona. This can be very bursty when used with your Q. It is important to charge your Power Chord when at the shop. To use this spell wisely pay attention to the chord you are playing. Use this with your Q to deal bonus damage. Use this with your W to stop the carry from doing damage to your carry. Use this with your E to slow them down.

-Q- This is all of your damage source. To successfully use this try sitting in the brush and come out for a Q with power chord. Remember this goes to multiple people so try to hit the support and the carry when in lane. When you get your hextech revolver this ability will give a decent amount of health.

-W- This is your most important ability but, the reason you don't max it out first because the heal is already decent and your Q will keep them from hurting your carry.

-E- I don't usually take this ability early because extra points in your Q can help get kills. Also, this acts as a shurelya's so there is no need for one. The main reason for this ability is for the slow with power chord.

-R- This ultimate in my opinion is one of the best in the game. When used right this can stun their entire team which can be a game changer. This is great when used with other ultimates such as, Enchanted Crystal Arrow , and Curse of the Sad Mummy

Greater Mark of Magic Penetration is to deal TONS of DAMAGE.
Greater Seal of Armor is for the crossfire of the ad carries on bottom.
Greater Glyph of Scaling Magic Resist is because to use most of your spells you need to get up close so you need to survive then close encounters.
Greater Quintessence of Gold is because you only get one GP5 and you get it later.

My masteries are just the standard support. 0/9/21

Meki Pendant- More mana regen than Faerie Charm
and also builds into Tear of the Goddess

Tear of the Goddess- Extra mana and regen for spamablility.

Hextech Revolver- Gives you spell vamp + ability power and also builds into WOTA for you mid.

Ionian Boots of Lucidity - Cooldown Reduction, but only for early game then you get Mercury Treads

Archangel's Staff - Builds from the Tear of the Goddess and gives you alot of mana.

Morello's Evil Tome- Gives you cooldown reduction and build from a GP5 item.

Lich Bane- Stacks on top of your power chord to deal TONS of DAMAGE.

Rylai's Crystal Scepter- Your Q will slow them and you get extra health.

Mercury's Treads You get this later on for the tenacity and the MR.

Clairvoyance - A must have for ranked games.

Flash - Definitely another great summoner spell especially for positioning your ult perfectly.

Heal - Not very good, since your W is basically a Summoner Heal.

Teleport - Just takes up a summoner slot. Why would you even get it.

Ignite - Your a support don't KS!

Exhaust - Actually is not bad at all, but if you are playing ranked CV is better.

Overall, Sona is my favorite support and she can extremely offensive as seen in this build. Hopefully you guys enjoyed my FIRST build ever and please give me feedback so I can improve.
