League of Legends mastery boost from approved eboost players. Fair pricing, live order chat, and payment held until your order is done.
Champion mastery is measured in games played well, and reaching high mastery on a champion you love takes dozens of hours. A mastery boost lets a verified booster play that champion on your account until the mastery level you ordered is reached, with the graded games you would expect from a high-elo player.
You pick the champion, the current mastery level and the level you want. Because the games are played in normal or ranked queues according to your instructions, you can also ask for the booster to prioritise wins or a specific role.
The order chat lets you set playing hours, ask for offline mode and follow progress game by game. Boosters never use the chat in game and never change any settings on the account.
Payment is held until the mastery target is reached and refunded for any part of the order that is not delivered.
