PearcePearceFebruary 22, 2026

Arknights: Endfield is a large-scale, visually exquisite anime-style game. Sanity, an important resource in the game, functions as the stamina system. Many players want to know how to quickly deplete their sanity. Today, Kobayashi will share methods for rapidly clearing sanity in Arknights: Endfield.

How to quickly restore sanity in Arknights: Endfield

1. Three-Step Method to Quickly Deplete Sanity

You can follow the steps below to efficiently complete your daily sanity tasks in just a few minutes:

Check and Prepare: Before the operation, open your inventory to check for any sanity boosters nearing expiration and prioritize using them to avoid waste. You can also replenish sanity by using potions in the "Sanity Recovery" option within the "Operational Manual" interface.

Challenge high-cost missions: Go to the " Operational Manual " and select the "Index" tab to find the "RE-Crisis" mission. This mission consumes up to 80 sanity per run; completing it twice consecutively will quickly use up 160 sanity, making it a key step in depleting your daily sanity.

Managing Remaining Sanity: After completing " RE-Crisis " twice, you will usually have little sanity left. At this point, you can choose to spend it on Operator EXP, Weapon EXP, and other missions in the "Operator Progression" (typically costing 40 sanity per run), or use the remaining sanity to farm weapon essences and other materials.

2. Principles of Efficient Management

Besides quickly clearing stages, the following principles can help you use sanity more wisely:

Main Story Priority: In the early stages of the game, advancing the main story takes precedence over everything else. The main story unlocks higher-level materials and features, and focusing too much on farming materials too early may lead to inefficiency.

The most reliable experience dungeon: If you're unsure what to farm that day or are in the early stages, prioritizing Operator EXP is the safest choice, as Operator EXP is a core resource that remains scarce throughout.

Avoid overflow: sanity naturally recovers over time (approximately 1 point every 7 minutes and 12 seconds). Remember to log in regularly to use it up and prevent wasting sanity recovery when reaching the cap.

3. Personalized Consumption Recommendations

You can flexibly adjust the allocation of sanity consumption according to the development stage of your account:

Early-stage players: Focus on investing in Operator EXP and skill enhancement materials to quickly level up your team and tackle main story stages.

After character development, players can, once the team reaches the required level, redirect sanity towards to the "Energy Alluvium" to obtain essences used for weapon enhancement and etching, allowing for in-depth strengthening of Operators.
