About license levelling
ZZZ License Level progress is tracked by the Investigation License, which tracks your progress in Hollow Zero mode, and each level pays rewards. Whether you are new or experienced, the service moves you up faster by clearing zones in the order that earns the most points.
Here is how it flows: you choose your range and extras, your login goes through the encrypted form on the order page, and a verified player completes the work. You get progress updates and a final confirmation in order chat.
How to set up your order
Completion Speed is optional. Express and Super Express raise your queue priority; timing is confirmed in order chat.
Range is a slider from level 1 to level 90. Set your current license level and your target.

Frequently asked questions
What rewards do I get?
Each license level's rewards, plus Resonia and Withered Crystals.
What do I need to start?
The Qualification Assessment Zone must be cleared.
Which levels can I choose?
Any range from level 1 to level 90.

How long will it take?

Is there a warranty?
Yes, after your order is completed: 8 business days, or 2 business days when a top-rated booster completes it. Some top-rated boosters offer their service without a warranty. Your order page shows exactly which applies as soon as a booster is assigned; if it shows no warranty and you want one, ask support for a different booster before the work starts.
Is it safe?
FullBoosts assigns verified players and protects piloted-service logins with an encrypted form on the order page. Only you and your assigned player can access those credentials while the order is open; they are erased when the order closes or a dispute is opened. Keep logins out of chat. Where Self-play is available, you play together and keep control of your account. Every delivered order has a 72-hour review window.
