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.
By far my favorite toon in LoL, Sona combines the damage of Jana, the heals of Soraka, the auras of Taric and the Ulti of Amumu with a snazzy little bonus for swappin auras. Mana regen and CD reduction. Period. At level 11 (or when you finaly make the fiendish codex) you should be able to solo the blue aura golems no problem, even if you're out of mana. The blue aura stacked on top of your CD reduction and MP5 will make it so that your ulti is dropped to aprox 40 sec CD, and you can constantly have all 3 auras going at the same time during combat. In fact if your hands are fast enough you can actualy find yourself waiting on an aura to refresh. Early game play safe, occasionaly snag a hit on the enemy if it serves your purpose but i use it moreso for last shotting creeps i'm not currently attacking (yes you can technicaly kill 3 creeps at once). And ALWAYS remember to keep a little mana left over for those "B!" moments, just to help everyone GTFO.
