Leveling up your Endministrator in Arknights Endfield is relatively simple, but things become difficult once your operator hits level 20.
Until you hit level 20, your pathway to growth is relatively linear. You raise the operator level with relevant materials. However, going past level 20 and hitting the level 40 cap will require you to complete a few extra steps. This guide will simplify the complete process and list all the items that you will need.
How to raise your Endministrator to Level 40 in Arknights Endfield
The first step is to raise your Endministrator to Level 20. If you’ve been playing since Jan. 22, you should have already reached that point by now. The difficulties begin from this stage, as you’ll first have to promote your operator.
- From the operator window, hover over the “promote” option. At first, it will say that the promotion is locked, and you need to raise the rank.
- You’re going to need three different resources. The first is the Protodisk. To earn Protodisk, run Protocol Space: Promotions. Repeat the process until you have the required number of items. Playing and clearing the rounds at greater difficulties will offer better rewards.
- Pink Bolete can be found from Rare Growth gathering nodes after you return to your hub. If you’ve harvested the nodes recently, you’ll need to wait till they items respawn.
- T-Creds are easy to earn; just do your dailies and finish side quests.
Once you’ve found all the required resources, click on promote from the operator window. To raise Endministrator to Level 40, you’ll need to opt for Promotion I. Once you’ve secured Promotion I, you can raise Endministrator to Level 40.

You’re going to require a lot more EXP materials to reach Level 40 than you did to hit the Level 20 cap. There are different ways to farm EXP materials, aside from simply playing with the operators and completing various quests and objectives.
