Arknights Endfield introduces many systems that feel familiar yet deeper than before, and Sanity is one of the most important among them. Sanity controls how much content you can clear, how efficiently you grow your Operators, and how fast your account progresses. If you misunderstand this system, you will constantly feel blocked. This guide explains how to get Sanity, how to use it wisely, and how to avoid common mistakes while playing.

Sanity is a resource that limits how many activities you can perform in Arknights Endfield. Almost every meaningful action, including story missions and farming stages, consumes Sanity. Once it runs out, you must wait for it to recover or use items to restore it. This system encourages planning rather than endless grinding.

Sanity has three key traits:

• 
  

  A maximum capacity that increases as your account progresses

  
  


• 
  

  A natural recovery timer that refills it slowly over time

  
  


• 
  

  Multiple ways to restore it instantly using items or rewards

  
  

Knowing how these traits work together helps you stay efficient without burning out.

How To Get Sanity Naturally

The most basic way to get Sanity is by waiting. Sanity regenerates automatically at a fixed rate while you are offline or online. Logging in regularly ensures you never waste regeneration time by staying capped.

You also gain Sanity through normal gameplay rewards. Story progression, tutorial milestones, and certain achievements often grant Sanity or Sanity-restoring items. These rewards are designed to keep new players moving forward without frustration.

Some limited events also provide bonus Sanity as part of daily participation. These are usually tied to event missions and reset regularly, making them a reliable source during active periods.

Sanity Restoring Items And Rewards

Sanity restoring items play a major role in Endfield. These items instantly refill a portion or all of your Sanity, letting you play longer when needed. You will mainly obtain them from:

• 
  

  Daily and weekly missions

  
  


• 
  

  Event rewards and seasonal passes

  
  


• 
  

  Login bonuses and compensation rewards

  
  

It is important not to use these items carelessly. Saving them for farming sessions, limited-time events, or difficult progression walls gives far more value than spending them randomly.

Some premium currency exchanges may also include Sanity options. These should be used carefully and only when you understand the long-term value of the trade.

Best Ways To Use Sanity Efficiently

Using Sanity well matters more than having a lot of it. Prioritize activities that give permanent progress, such as story missions, Operator upgrades, and base development. Early on, story content offers the best return because it unlocks new systems and farming stages.

When farming resources, focus on stages with balanced drop rates and time efficiency. Repeating inefficient stages wastes Sanity and slows growth. Planning your farming schedule around daily resets also helps you maximize rewards.

A smart approach includes:

• 
  

  Clearing story chapters before heavy farming

  
  


• 
  

  Farming materials only when you need them immediately

  
  


• 
  

  Avoiding overfarming low value resources

  
  

This mindset keeps your account moving steadily forward.

Sanity And Event Management

Events are where Sanity management truly matters. Event stages often have better rewards than regular stages, but they are only available for a limited time. During events, it is usually correct to spend most of your Sanity there.

Before an event starts, avoid overusing Sanity restoring items. Save them so you can push harder during the event window. This approach allows you to clear event shops, earn rare materials, and prepare Operators for future content.

Daily event missions often refund some Sanity indirectly through rewards, so completing them early each day improves overall efficiency.

Common Sanity Mistakes To Avoid

Many players struggle with Sanity because of poor habits. One major mistake is letting Sanity stay capped for long periods. This wastes free regeneration and slows progress without you noticing.

Another mistake is spending Sanity on stages you cannot clear consistently. Failed attempts still consume Sanity, making experimentation expensive. Practice new strategies on lower difficulty stages before committing.

Finally, avoid panic spending Sanity items just to keep playing. Playing less but smarter often leads to better long-term results.
