Playing against Sona

How to counter and exploit weaknesses

1

Sona is one of the squishiest champions in the game — engage on her directly to kill her in one combo.

2

Punish her in the early game: she's extremely weak before her items and levels.

3

Her R is a linear skillshot: dodge it and she has no hard CC left.

4

Engage supports (Leona, Nautilus, Blitz) dominate her in lane.
