Scientists need more than their lab coats to survive the threats lurking around the facility in Abiotic Factor. Wearing the appropriate defensive gear can do more than ward off attacks. Some armor pieces can deflect bullets and even heal the wearer without significantly relying on healing items. With that, keep reading this Abiotic Factor Best Armor Set Tier List to learn what to go for when surviving the facility.

Abiotic Factor Best Armor Set Tier List, Ranked

The items gathered in this Abiotic Factor Best Armor Set Tier List went through a thorough examination of their stats, unique effects, and overall bonuses. However, although this analysis aims to compare each armor set’s capabilities objectively, it’s essential to remember that this list shouldn’t define a player’s preference. Ultimately, select the armor set that best aligns with your enjoyment and strategy when playing Abiotic Factor.

10. F.O.R.G.E. Armor Set

The F.O.R.G.E. armor set can be a step above early-game defensive gear.

8. A.T.O.M.S. Armor Set

Despite the A.T.O.M.S. armor set offering excellent defensive capabilities, it still falls short when compared to other options in this tier list, particularly because of the rare items needed to craft its components. Nonetheless, this late-game option makes it highly effective against firearm-wielding opponents, such as those from the Order. Also, wearing the helmet grants Airtight Seal, a great buff when exploring the Mycofields.

Armor Set Pieces

7. Legate Armor Set

Like the A.T.O.M.S. armor set, the Legate armor set is a late-game choice that requires players to open Inquisitor Crates to get each component. This non-craftable defensive set can be an excellent choice for Abiotic Factor players in multiplayer servers. In particular, wearing the entire set grants Rite of Command, a buff that enhances the speed of all nearby allies, including the wearer. Dodging attacks with this armor set equipped can be easier than normal.

6. Hyperion Armor Set

The Hyperion armor set joins this tier list of the best armor sets in Abiotic Factor as one of the ideal late-game options. Crafted using rare materials found in the Residence Sector, particularly in the Voussoir portal world, this armor set surpasses others with its built-in enemy detection system. Doing so increases survivability by allowing the wearer to be wary of hostile NPCs even before they appear. However, like the other previously mentioned options, the Hyperion armor set doesn't make it to the top spots primarily because of the difficulty of crafting its ingredients.

Arguably, one of the best armor sets in Abiotic Factor, if not THE best, is the Hex armor set. Although it provides fewer defenses than other options in this list, this lightweight option has armor set bonuses that no other defensive gear in the game possesses: the ability to heal light and/or heavy bleeding.
