my first public build, maybe i will add some content soon

"Supports need exhaust!"
Not me!
Cmon, search your feelings... Sona is clearly a mana *****.
If you want to support your lanepartner longer than 3 min you need clarity.
And sometimes even your AD Carry will be grateful for some extra mana.
And Flash is a "must have" so there is no space for Exhaust, sorry dude.

I can slow enemys with powerchord and i can boost the damage of my whole nearby team.
That should be enough.

sure, its your first duty to heal yozr teammates. But a little damage buff at the start is pretty nice. And dont forgett your powerchord. You can do some great damage at the start.

With Sonas speedbuff we dont need boots as early as other champions.
Gold is all thet counts. The more golditems you have the less creeps have to be killed.
And as a supporter, you should not kill a single creep.
So give me gold, gold and more gold, i really need it.
The earlyer you buy your golditems, the more gold you get.
So dont be shy, after the first 900 gold port back to base and go shopping, if you buy some wards, your teammate wont be angry.
