Once Human Deviations Tier List: Best Deviants for Combat, Territory & Crafting

Once Human Deviations (also called Deviants) are special companion creatures that provide combat assistance, base automation, crafting bonuses, and various utility effects. Choosing the right Deviations can significantly improve survival efficiency, resource production, and combat performance.

Deviations are divided into three categories:

• Combat Deviations: Fight alongside you and provide damage, defense, healing, or crowd control.
• Territory Deviations: Work inside your base to automate resources and improve production.
• Crafting Deviations: Provide utility effects such as repairs, crafting support, or special items.

This Once Human Deviations Tier List 2026 ranks the strongest Deviants based on overall usefulness, progression value, and endgame performance.

▍S Tier Deviations (Best Overall)

These Deviations provide the highest value across multiple stages of the game. Most players should prioritize obtaining and upgrading them.

Festering Gel is considered one of the most reliable Combat Deviations because it improves survivability in solo exploration, bosses, and dungeons.

The Digby Boy is one of the most valuable Territory Deviations because passive mining helps players maintain a steady supply of upgrade materials.

▍A Tier Deviations (Strong and Highly Useful)

These Deviations are not always mandatory but provide excellent benefits for specific builds or progression goals.

Rebecca becomes especially valuable in later progression because it improves the efficiency of other Deviations placed in your base.

▍B Tier Deviations (Useful in Specific Situations)

These Deviations can be very strong depending on your build or goals but are less universal.

Electric Eel becomes more valuable for players with large bases that require more electricity for production systems.

Growshroom and Buzzy Bee are better choices for players focused on farming rather than combat progression.

▍C Tier Deviations (Situational Picks)

These Deviations have useful effects but are usually replaced by stronger options later.

Some C Tier Deviations can move higher depending on your build. For example, Polar Jelly becomes much stronger for Frost Vortex setups.
