How to play as Karma
Karma mains describe Janna as an enchanter Karma can pressure in lane, so use early Inner Flame(Q) and autos to claim space instead of waiting passively for later fights.
Keep moving laterally and use Inspire(E)'s speed to avoid Howling Gale(Q); if Janna spends her tornado, step up for poke or a Focused Resolve(W) tether rather than walking straight into its return path.
Karma's Inspire(E) protects an ally and adds movement speed, while Janna's Eye of the Storm(E) shields one ally and increases their attack damage; those shields can blunt each other's poke, but Karma's Mantra(R)-E reaches nearby teammates too.
