Login to https://leagueoflegends.com
Click on "Your Username" -> "Settings" located in top right corner.
Change the Email address by clicking on the email address field. (You will see the old email address there, just click on it and it will work)

Change the password from the same page.

We like to leave FULL power to our customers. Some customers like champion capsules, others like pure Blue Essence. Therefore we leave the champion capsules UNTOUCHED. If you want pure Blue Essence then just head to your loot and open all champion capsules, disenchant all the champion shards and use the mission tokens to buy champion shards and disenchant them as well. Who knows maybe you like a champion or two and decide not to disenchant those.

The loot estimate is using the actual value of the champion and not the disenchanted value, this is why we recommend using the champion shards instead of disenchanting.

Once you buy an account make sure to check your email for a "Your Order is complete" email. Open that email and the account info is inside. You will also find the account information on the website after payment completion.

Every account comes with a lifetime warranty that allows you to get replacements. The warranty only applies to accounts banned for botting, bans for flamming and other types are NOT covered by the warranty.
You can get a replacement within seconds by following these steps: Join our discord server using this link or using the "Get Help" Button at the top of the page.
Open a ticket using the #support-ticket channel and by clicking on Envelope icon.
Follow the instructions provided by the Bot and you should get a replacement sent to your Email instantly.
We must have access to your banned account in order to replace it.

You CANNOT benefit from the warranty if you change the username used to login, however changing the ingame name is totally fine.
