Ok now lets start!
THIS IS A CARRY BUILD NOT A SUPPORTER!
I hope this helps to play Karma succesful!

Even in her youth, Karma exhibited almost superhuman composure. While her peers explored the torrent of emotions that came with adolescence, Karma meditated in the Lotus Gardens. She was convinced that the true path to enlightenment was a journey inward, to a place within the self, overlooked by most. She exuded such inner contentment that she quickly became a go-to mediator and confidante in her village. Her instructors used to say: "That girl can not only weather a storm, but calm it." Karma did not live extravagantly; her parents owned a local business selling antiques in the Navori province and they often struggled to provide for themselves, though they did so with cheery optimism. Her most prized possessions were two exquisite fans taken from her family's shop.

When Noxian troops invaded southern Ionia, her village was one of the first to fall. The villagers who survived the assault were captured by Noxian forces. It was then that Karma found her calling. By exploiting the insecurities of the Noxian commander, she negotiated the safe release of the villagers to the northern lands. She was present at the Placidium, where the Elders had considered surrender until Irelia's impassioned last stand renewed the Ionians' hope. Karma used this hope to solidify the Elders' commitment to remain defiant against the Noxian onslaught. For her devotion and charisma, Karma was made the figurehead of the Ionian resistance. She never compromised, and she shared every hardship with her people, even when it came to combat. By tapping into her inner resilience, she discovered that she could bring great force to bear against her foes on the battlefield. She modified her fans into lethal implements, and was tutored by Janna to enhance their effects. The Noxians called her "The Enlightened One," a nickname she embraced, and one which they would come to dread. She joined the League to represent Ionia in the ultimate political arena.

"Her fan technique is a deadly art of grace and poise, but her truest strength lies in the hearts of those willing to die alongside her." Irelia, the Will of the Blades

Heavenly Wave: Karma sends forth a wave of hidden blades from her fans, dealing magic damage to units in a cone in front of her.

* Mantra Bonus: In addition to dealing damage to enemies, Heavenly Wave will also heal allies in the cone. The amount healed is amplified depending upon the amount of life Karma, or her allies are missing


Spirit Bond: Karma bonds an ally or enemy creating a beam between them. Bonded allies have increased movement speed and bonded enemies have reduced movement speed. Enemy units that come in contact with the beam take magic damage, and champions who pass through the beam receive the same movement speed modifier as bonded champions.

* Mantra Bonus: Karma strengthens the bond to double the effect of the movement speed modifier.


Soul Shield: Karma summons a protective shield that absorbs incoming damage.

* Mantra Bonus: In addition to the shield, energy radiates out from the shield, dealing damage to enemy units around the recipient.


Mantra (Ultimate): Karma empowers her next ability to do an additional effect. Mantra is available at level 1 and does not require a skill point.

Pros:
-amazing farmer
-great harass
-nice escape and defense skills
-good amount of dmg
-ulti ,without wasting a skillpoint, at the beginning!

Cons:
-Very Squishy
-looks like a granny

at first the most important thing: GO MID because u are a really farming machine and u need all this gold


The best ist when u always stay at 1/2 or 3/4 of ur life because ur passive who give ability power. dont worry u can heal u with mantra + heavenly wave if u need it.

The greatest thing at Karma is that u can play very agressive without getting much dmg.
normal play rotation is Mantra ->Heavenly Wave->Spirit Bond -> Mantra -> Soulshield when ur enemy isnt dead repeat this.

yeah....and then just farm in early say ss and do the other normal things u do in a game

Here a little Summary

1-6 Early: Farm,Farm,Farm,and harass the enemy at early u should get Ionian Boots and maybe a the Giants belt or the ap staff.
7-13 Midgame: Help ganking ur team and try to farm more so that u get abyssal scepter at the end of the midgame
14-18 Endgame: Time of the Teamfights. Stay always behind ur team and do dmg with ur shield that u give the tank or a meele with mantra so u can damage the enemys and heavenly wave with mantra cuz that heals ur team and that can be important to win a teamfight. when u escape set s spirit bond on a low life mate to help him escape. Dont forget: Always use ur shield to do damage cuz its a ****ing nice spell to protect ur tank and doing damage to the enemy.

ok this is the end of the Guide i hope u like it!

oh i forgot: Sorry for grammatical mistakes :/

Have Fun!
