how do you beat karma supp ?

Look up a video on her play style and learn it thoroughly. Once you fully understand her kit.....you will have no issues countering her. Mainly you just need to avoid the Q and pay close attention to the sound/look of her ult.

Holy shit where to begin.

Be behind minions but not close to them, her Q does explode but the radius is as small as a church boys shorts her tether you just walk away from/cc her/use your dash,blink,jump/kill her while shes in "please kill me" range Her shield is too small to even match the damage of a poke spell with half her shields cooldown so her shield isn't going to save anybody

She doesn't hard counter any support the same way she isn't hard countered by supports

If you're adc dont get hit by her obvious poke and use your dash to make her entire kit useless,or kill her her shield aint shit on someone that doesnt stack resistances and her mantra W aint shit on a champ that doesn't stack health.

morg can destroy her if you can hit your black sheild correctly. Basic, she is a poke mage that is extremely squish. Thresh, naut, leo all can go in on her, stun her, and she basically dies before the fight bot lane even starts giving you that 2v1. You have to be aggressive against her. If you let her push you then she wins lane hard.

giving her a b-i-t-c-h slap, dat simple

with braum. by surviving laning phase. sustain with soraka. Karma is just kind of a lane bully, but she falls off so hard. Take someone with a heal. Braum's shield destroys projectiles.
