Good build

Outdated.

If you read the "Laning" part you will see around 5 "thus"'s; thus here thus there, a bit disturbing as it shows you never reviewed at least a part of what you wrote down. That can cause information to be duplicated and it just looks unproffesional.

"I play her duo lane as support. I pick only a minimum of farm so I need a cheap build, while giving my carry mate the chance to get a very expensive build quite early." - you pick a minimum of farm? you shouldn't farm AT ALL unless your ADC is in the base and creeps are at your tower.
"Blue Buff is sometimes offered to support." - nop, unless you play in like -1500 elo. It goes to the mid > jungler > top > adc > support.

For items you should get apart from the gold per sec dagger the philo stone as well.

That's all I read right now, it's outdated so I won't continue.
Guide is decent with some mistakes here and there, good job nonetheless.

Needs update.

제가 영어를 잘 못해서 죄송하지만 한글로 쓰겠습니다. 이렇게까지 댓글을 쓰는 이유는 이공략으로 많은 도움을 얻었기 때문입니다

처음에 이공략을 보곤 이해도 안되고 활용가치가 있을까 하는 의구심마저 들었는데요

카르마를 주력으로 하는 입장에서 서폿에 대한 많은 자료를 보았으나 이렇다할 성과를 얻지 못했는데요

이공략으로 굉장한 효과를 거두었네요

It's very nice and im heard op karma support. Please update.

Your nice think appreciated me.

This is a very good build. The positioning in teamfights was most helpful. Thank you for writing this guide.

each I play with I feel good

pretty op but I began with philosoph stone

Wall of text. It conveys the essentials, but due to the bad format I wouldn't rate it above 60%. It has potential tough and is the only decent support-Karma build on the site. I hope you can improve it...

Nice guide with a updated skill tree

Hi Maramix! I'm not sure if I've upvoted your guide before or not. Is there a link to it on my guide? I'm pretty sure there is... somewhere. Do you want to take over managing my guide? Please let me know; I am too busy and you seem like the most qualified person.

well thats your opinion but I do not agree. Have you tried my build?

I'm currently testing a bit with Locket of the Iron Solari as an alternative to Randuin's Omen in case you do not need armor that much but run into inventory space troubles so you want to upgrade Heart of Gold. expect that to be added soon.

However Karma is going to be remade, so all those efforts are only of temporary use, thats why I test in low power mode ... lets see when the new Karma comes and what it offers.

karma is not a good support, better ap mid/top
