Increase your Champion Mastery in LoL fast and without any problems by placing an order at Kingboost!

League of Legends Champion Mastery is the ultimate way to showcase your skill and dedication to a specific champion. With the recent rework, the system now offers more rewards than ever: cosmetic upgrades, mastery crests, emotes, Hextech loot, and champion capsules. However, farming mastery points is a long grind, heavily dependent on consistent wins and high performance grades.

KingBoost makes this process fast and reliable. Our boosters play piloted only, ensuring direct control and maximum efficiency. You can choose the boost type: Tier Boost for a quick climb through mastery tiers, or Mastery Level Farm for steady accumulation of mastery points. Execution speed is flexible — from standard progression to speedrun priority, depending on your urgency.

As a result, you’ll reach the desired mastery level or points with your chosen champion, secure many wins with high performance grades, and unlock Hextech chests, key fragments, and champion capsules. You’ll also upgrade your mastery crest and emote, while gaining Blue Essence, profile experience, and improved account stats.

YOU WILL GET

  • The selected Mastery Level reached or Mastery Points earned with the specified Champion
  • Many Games Won with High Performance Grade
  • Chance to earn Hextech Chests, Key Fragments, and Champion Capsules
  • Upgrades to your Mastery Crest and Emote
  • Improvement of your Account Stats
  • Blue Essence and Profile Experience obtained during the boost
REQUIREMENTS
Chevron
  • Account level 5+
  • The selected champion must be unlocked on your account

A little slow to complete- but very competitive price.

Did this for Marvel Rivals boosting, I've used these services before in other games and generally get same day turnaround- but normally x3 the price.

This seemed a little too good to be true, but thought I could try it.
Did get a response in about 30 minutes of the order, first person they assigned me to did not respond until late in the night, to which they automatically moved me to someone else who responded pretty much instantly. Took about 3 days to complete, as the booster said they had a lot of throwers/issues in their games and they were playing the full time.
But all my requirements were met and my rank was achieved. :)

Great customer service

So I ran into an issue with my order, which was my own doing by not clicking selfplay and left it on piloted. I messaged king post saying I had messed up and said I wanted to selfplay not pilot and writhin 5 minutes my order was updated and was already put into a session.

These guys are fast and reliable and great customer service. I am happy I jumped and used these guys and would trust to buy more services through them. I think the prices are fairly priced for the exceptional service you receive.
