Some people think feeding is easy but they are wrong. In this build you are going to learn how to become a pro feeder.
What you will need:
-Useless champ wit no power whatsoever
-Huge number of email accounts (you are gonna get banned after a few games if you are good)
-A lot of sense for finding enemy ambushes
-A gun when someone finds out where you live in a real life
Runes and Masteries
As a good feeder you must be available to feed the enemy in a lot of occasions. To be able to do that you must reduce the time spent dead to minimum - trough runes and masteries.
Try to buy items that doesn't effect your status at all and NEVER buy armor or magic resist items although buying an item like Zhonya's Hourglass or Banshee's Veil can help you at feeding your favorite enemy champ. Try to buy as many wards as you can so you will be able to see where an enemy champ is in order to feed him as quick as possible.
Once in the game try to wander around alone and go to suspicious bushes often. The best strategy is to run around the jungle all the time and sooner or later you will meet at least an enemy jungler. Try to use champ that has low health, armor and magic resist so you will be able to feed efficiently. Another option includes waiting at red buff, blue buff, dragon or baron - someone always comes to that place. When engaged by enemy champ try to offer a minimum resistance possible.
After the game
If you have succeeded you will get many praises on the end of the match in form of:
-report ''champname'' for feeding
-i'm gonna kill u ''champname''
If you did everything described in this build you have become a PRO FEEDER!
