Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
Sona is full support. **Impotent** She cannot be alone!!!! Giving her a lot of mana, and mana per sec can make a huge different when helping out your teammates. During the game there should not be that may kills then assist. If the enemy have champions that stuns a lot i recommend having least 2 mercury's treads depending on the situation, for faster mana per sec innervating locket, and when face tankers use deathfire grasp and crescendo, so they can take magic damage and see them dance while your team teams finish them off. Rod of Ages is not suppose to be there but it will a substitute for Shurelya's Reverie(http://www.mobafire.com/league-of-legends/item/shurelyas-reverie-111) which you really need more then Rod of Ages get this when you get mercury's treads.
