Build and Runes
Do not clump in teamfights in a line – as the Sona will make your whole team dance!
Sona is extremely squishy at earlier levels. Try to coordinate an assault against her early.
Sona gives good overall utility and harrass, but her spells cost a lot of mana. Try to force her to spam them early game, then make a trade when she’s low on mana.
Her Q poke doesn’t target you if she can’t see you, so hiding in an unwarded bush is a good way to lower her harass.
