tank? not really

Since you are a meat shield and being sona easily draws aggro it's a great way of playing her. I have not thought of MS for her, but since my tanky sonas tend to not die after lvl 10-11, it might be the way to get good ap. Add to that a Lich Bane if your team is on a roll and you can do lots of damage too.

I'd never choose Ninja Tabi though. Most champs armour scales with level, but not their MR. So go for mercs. Also it's the best tenacity item in the game! Great for a tanky champ who wants to draw aggro!

Solid build and a solid guide. :D
