This article explains the upgrade of Potential in Arknights: Endfield, including whether you should increase Character Potential and Weapon Potential.
Table of Contents
Should You Increase Potential?
Increase Potential with Duplicates

In Arknights: Endfield, it is recommended to increase a Character's Potential when you obtain a Duplicate. However even without upgrading Potential, the character can still perform effectively in combat by upgrading other stats.
Skip Potential on 6★ Weapons

Increasing a weapon’s Potential only boosts its stats and multipliers. Therefore, we recommend keeping high-rarity (6★) weapons available for other characters instead of investing in Potential.
Raise Potential on 5★ or Lower if Needed
You can generally increase the Potential of 5★ or lower weapons when you obtain duplicates. However, if you are short on a specific weapon type, it’s better to save the duplicate rather than forcing a Potential increase.
How to Increase Potential
How to Increase Character Potential
Pull a Duplicate Character From Any Banner

When you pull a character you already own from the gacha, you will receive an Operator Token. Operator Tokens are required to increase a character’s Potential.
Open 'Operators' from the Menu

Once you've obtained an 'Operator Token', open 'Operators' from the Menu.
Increase Potential From the Potential Tab

When you have a character whose Potential can be increased, select the Bottom tab. From there, select 'Upgrade' to increase the character's potential.
How to Increase Weapon Potential
Open 'Valuable Stash' from the Menu

To increase a Weapon's Potential, first select 'Valuable Stash' from the Menu.
Select a Weapon → Details

Select the Weapon you want to increase the Potential for, then choose 'Details' in the bottom right of the screen.
Open Potential Tab

After selecting 'Details', open the Potential tab in the top-left of the screen.
Add Duplicate Weapon to Raise Potential

In the Weapon Potential menu, select the slot in the lower-left and choose the duplicate weapon. Then, select 'Raise Potential' to complete the upgrade.
