Upgrade your Arknights: Endfield account with Authority Level Boost!

Authority Level is basically how far you’ve progressed in your account. If you want to unlock story missions, get access to more gear blueprints, and boost your maximum Sanity, leveling up is the way to go. As you level up, you’ll also snag some Oroberyl that you can use for Headhunt.

At the start, leveling up is pretty easy and doesn’t take much effort. But once you hit around level 50, it starts to slow down a lot. You’ll need to complete a bunch of side quests and do open-world stuff like hunting for chests and solving puzzles.

That’s where KingBoost comes in! We offer an Authority Level Boost service that lets you skip the grind. Our skilled players will take over and help you reach your target Authority Level quickly and smoothly. 

YOU WILL GET

  • Desired Authority Level obtained
  • Access to Story Missions and High-Tier Content
  • All currency, loot and resources obtained during the boost

Been using KingBoost for a couple of years now, and the experience is always flawless. From their support agent on discord who replies instantly about any issues, concerns or progress updates. To their booster who completed the guns before I expected him to. I’m over the moon with my experience and will continue to use them as and when I need. Couldn’t be happier with their customer service, after sales and booster who always delivers over and above what I need. Service agents are always so polite and patient and eager to assist with anything needed. Overall 10/10 experience and will continue to use KingBoost.net for years to come

Honestly I had left a review that was a bit lower than I usually would but customer support reached out to me to make things right including some free services and honestly I appreciate it
It shows that these guys do take this seriously
So if you have any mistakes that occur from your end or theirs definitely reach out and the will make things right
I have used them several times now and each time was great except for one hiccup but at the end of the day they made sure things turned out well
