Notes
This is an Alien Gear item.

This armor has 2 less DEF than the T13 Hydra Skin Armor, doesn’t have the DEX bonus of tiered leather armors, and unlike most UT armors, does not provide any additional stats. Instead, it has a special effect which renders you invulnerable if you take any damage when at critically low health, albeit once every four minutes. It’s not the most practical effect, but this armor giving you more reaction time to back off or escape to the Nexus can still be a godsend in extremely tight situations.

However, the armor’s most important benefit is being a part of the Alien Gear sets. When worn with any Alien Core, the resulting set bonus will provide a significant stat boost depending on the core worn. With an Alien Weapon and/or stronger cores added in, the set bonus will get even more powerful. So, if you have the rest of a compatible Alien Set available, the completion of the set bonus usually outweighs the loss in raw stats.
