yeah, late game sona is all about mana regen for constant aura twisting. i also think it's interesting that your build is the only one other than mine that focuses on heal and leaves hymn of valor at 1 for so long. i feel that with the fixed mana cost change to songs the heal focus is greatly strengthened.

Thanks for the comment on the Masteries, Silanthous. I switched it out to your recommendation, and I've got a feeling it will be a big help, especially seeing as regen really outweighs max mana.

I also put up a tank sona build. you should check it out =)

Why go for 4/4 expanded mind if you don't use a chalice? is it purely for if you finish your archangels? if so, wouldn't those points be better spent elsewhere like move speed or faster res time or even improved clarity to aid your carries/tanks?

I like the focus on team aura items though.

Xaioli, beat to the tank sona race once more.

Change your sunfire for banshees and you get my +1

Hmmm i play this build with Taric xDD its really good, u can change sunfire and put banshees
+1

I played with this guy using this build and we ran 3-0 stomping every single game. Very good support.
