The most efficient way to level up in Endfield is by consuming Stamina. Because Stamina only recovers to a cap, once you’ve used it, you should tackle Energy Alluvium and Temporary Energy Alluvium.

Check Required EXP from the Main Menu

You can check the amount of EXP needed for the next level in the Player Information section at the bottom‑left of the main menu. That required EXP climbs as your Authority Level rises.

Consume Stamina in Protocol Space

The most efficient way to earn EXP is by consuming Stamina (Sanity). Since Stamina recovers gradually, use it in the Protocol Space so it doesn’t overflow.

Tip!	1 Sanity is recovered every 7 minutes and 12 seconds, for a total of 200 recovered over 24 hours.

Use Stamina Recovery Items to Level Up Faster

Besides natural recovery, you can replenish Stamina with dedicated recovery items or Origeometry. If you want to raise your Authority Level quickly, restoring Stamina to grind Protocol Space is a smart move.

Clear Energy Alluvium

Energy Alluvium are places marked by white rifts scattered across the field. Powerful enemies appear there, so be well‑prepared before you tackle them.

Check Energy Alluvium Locations on the Map

You can locate Energy Alluvium on the map. Use the map when searching for Energy Alluvium.

Clear Temporary Energy Alluvium

Temporary Energy Alluvium, which appears as blue rifts, are combat encounters where you must face multiple enemies. Unlike standard Energy Alluvium, these do not appear on your map, so you will need to discover them through exploration.

Complete Side Missions

You can earn EXP by completing missions outside of the main story. You can check the amount of EXP rewarded in the mission details, so use that to prioritize which missions to tackle first.

Complete Operation Manual Missions

EXP is also granted for completing missions in the Node tab of the Operation Manual. These serve as a useful guide during the early stages of the game, so be sure to check off each objective as you progress.

Gain EXP Through Field Exploration

You can also gain experience by unlocking gimmicks and Chests on the field. Since you can obtain other useful items besides EXP, it pays to be proactive in your search.

Exploration Element	EXP Gained
Items	10 EXP
Broken Robot	50 EXP
Chests	Varies by rarity Highest rarity chest gives 160 EXP

Regular Enemies Give No EXP

You will not gain EXP simply by defeating regular enemies wandering the field. Make sure to focus on completing specific activities that increase your Authority Level rather than just grinding mob kills.
