This is lame and weak.

Karma has only 2 reliable damage spells as opposed to other champions with at least 1 spammable spell OR 3 reliable damage spells.

Those 2 are Heavenly Wave and Mantra-Soul Shield. That means in order to do decent damage, you'll require lots of CDR, and testing with max CDR, its still not too easy to mantain a Mantra to Soul Shield damage.

Your skills are around yourself, closed ranged. As an AP Carry, walking into the fray and doing that is your only way to do damage. Otherwise, you won't be able to do consistent damage. AND if you walk in with that build, you won't ever walk out.

Which AP Carry has 2 support-type spells? If Nidalee with great damage is still considered a semi-support, Karma will be a full support seeing all her skills BUFF her teammates or HELP in a way.

Your guide has no pictures, little colour and overall it is not even NICE to look at. Nor is it GOOD to read the entire thing.

It's a plain guide but decent, I'm a very avid Karma player and just as support Karma, CDR should be your main objective, it will greatly increase your damage output as well as an "off -support status in team fights with your mantras being up every 12 seconds at max CDR in team fights. As for the items, I think Morello's evil tome, Deathsfire grasp, frozen heart, and the CDR boots should be at the most priority. Don't be afraid to go tanky with with karma because with your passive, it like having a free Deathcap when you get low enough on Hp. As far as her heal, when you get to the high AP levels you are healing for decent amounts and it's Aoe, plus is on a short CD, so I think "Off-Support" Karma is going to see more play with all the nerf to straight support champs, such as Taric and Sona. Also, I don't like how you said, don't use a mantra point on Spirit bond, well, In team fights it can be a great asset, and slowing for 36% instead of a ****py 18% is way better. As far as damaging people with it, don't over extend yourself to get some mediocre damage, but instead cast it directly behind your target on another enemy champ or even a minion. Other than that, Goodjob
