+1 overall, this is great for a start

i think you could still better code this. for instructions, check out jhoijhoi's guide on making a guide. also more situational runes and item should be needed. make your pros/cons chapter into columns. maybe more information and indepth about supporting with sona will be needed. i'd also recommend turning on require comment to vote.

keep up the good work!

I dont usually need those items early. And I do sometimes use CDR boots. Depends really on if im spamming like a bech or not. I will probably update the guide at some point. My items actually are bought when ever I need them. So the order is what ever needs to come 1st. But thanks for your advice.

Hi! Not a bad start for your first guide. I'm going to go through it with you and suggest some things that you could possibly change.

Alright, first I see your runes. Good choice of runes, but you have a total of 10 seals (Whoops!) It's not a huge deal but you might want to think about changing it for correctness sake.

Your skill sequence is fine but I'm confused a bit by your item choice/sequence. Instead of building Mobility Boots for speed, have you ever thought about building Ionian Boots of Lucidity for the much needed CDR that Sona craves? She has a movement speed boost, heals, and an AOE stun if she ever gets in too sticky of a situation. Also, I think it is always the case that support items should be finished first before finishing items for yourself when playing support, mostly because your team benefits more from doing so. This being said, shouldn't Shurelya's Battlesong and Locket of the Iron Solari be finished before Archangel's Staff? Just a thought.

Next we have masteries. Good choices down the trees, but if you're going to take Heal, I would suggest taking a point in Summoner's Resolve . The extra heal is a life saver.

The overall feel of your guide is good. You may want to go through and spell check things (I noticed a couple mistakes myself) and expand on your views of what to do with Sona, why you picked what items/runes/masteries, and warding locations. More coding is always good and I would suggest it. If you need help, JhoiJhoi has a guide about making good guides (It's in my sig). Again, good start!
