I've been playing with the (AD) Sona guide and this guide appeals to me in the same way. I like the addition of Manamune, although, the health potions seem a bit off. Since this build suffers from a lack of regen (compared to Chalice of Harmony), I believe that mana potions would be more appropriate.

I'll definitely be using a hybrid of this guide and the "(AD)Sona Wins" guide.

That said, I still think this guide is great! Thanks for making it!
