Was Plat 1? back in SEA, but that was three years ago. When I came to OCE, got really tired of climbing and hardly play ranked. Do still play norms so have a fair idea of whats still going on.

Was testing out things to see if it works. I find that Font of Life is a bit meh for Sona, since her only stun is her ultimate and her Power Chord E, which is somewhat useless in teamfights.

While Revitalize is good, the problem is that it doesn't offer as much as the other runes. Cosmic Insight gives you much more. Furthermore, you'll most likely be building a lot of items with +% heal and shield bonus anyway.

But, if you're against a harder lane, you could opt for Revitalize + Chrysalis since it gives you a bit of survival early on which can scale later on.

Honestly, I find that getting Tear of the Goddess is redundant as the fully stacked Manaflow Band as well as the mana regeneration from the support items or the Chalice is enough to keep your mana up, as long as you don't needlessly spam it.

As far as Seraph's Embrace go, it's an alright item, but you need to remember that its somewhat useless until you upgrade it. The gold you spent can normally get you better items, so unless you have a lot of gold for some reason, it's normally better to get something else.

I'm currently still working on the Celerity build although it doesn't seem very promising at this point. Currently, the one I'm working on involves a Tear where you can near permanent upkeep of Song of Celerity but still is a bit sketchy atm.

On the Resolve Tree, if I'm going for it, would go for Revitalise and Chrysalis. Bone plating requires you to get some form of HP for it to be useful otherwise you would still explode too fast. However, the Inspiration tree is currently really good as a secondary with the magical footwear and 5% CDR. Resolve isn't bad per se, it just gets outclassed by Inspiration at the moment.

Now that you mention it. I'm going to try out the Song of Celerity version and will get back to you.

Yes, Blue is not meant to be full damage version since the utility you provide will still be better. Also, this is due to Sona not having the best AP Scaling. Always interested to see another point of view so I'm fair game.

1. A passive lane is normally when both sides aren't pushing for any advantages, instead the ADC will just farm while the supports sit back and not do anything except ward once in a while. (This also implies both jungler won't come down).

2. Sometimes when you're lucky, you can score an extra critical hit when you proc your Q bonus damage or Power Chord. It really doesn't make that much difference, but if it proc during a fair trade, it can put you at an advantage (It's a bit like gambling)

3. You should mentally make a note of it, but if you can't you can just look at the bar where buffs are. You'll see a count of how many spells you have used.

4. Because Sona is the most dominant early game. The other issue is her Heal isn't that good in terms of mana-efficiency since it scales up based on the amount of levels invested in it. You want to use Hymn of Valor to abuse the enemy or force them away from the lane so you can gain an advantage for your ADC.

5. Basically, Sona's abilities work as such. (Mainly for Q and W) When you use the skill, you will damage or heal your enemies or allies respectively. After that, an aura (or a circle) will appear around Sona. Allies that step into said circle will gain bonus effect. For your Hymn of Valor, they will gain bonus damage on the next attack while Aria of Perseverance will give them a shield. Tagging them literally means going to them so that they are in your aura zone to give them the benefit of said aura.

6. Thanks for pointing it out. It's supposed to be Ignite will be useless against them when they DIVE on your carry.

7. Yes, that's exactly the reason why the Green Build (or Heal Build) is a lot better on her. The items you buy on her generally revolves around those that grant CDR or Mana Regeneration or both. The Blue Build (or Damage Build) is specifically for when your team has little to no magic damage. (Say they go for a Zed mid, Nasus top and Zac (tanky) jungle, your allies damage will be significantly reduced since all they need to do is stack armor, so you get some damage to deal with that).
