Playing against Karma

How to counter and exploit weaknesses

1

Karma is strong early but scales poorly — she falls off in effectiveness compared to other supports/mages in the late game.

2

Her RQ is her only real burst: dodge it and she has no offensive threat left.

3

W roots after 2s: break the connection by moving away before it triggers.

4

Focus her in teamfights to prevent her from shielding her entire team with RE.
