"The Longevity is a unique scientist suit that prioritizes sustain through its 2.0 Periodic Healing trait. At maximum upgrade, it provides 253.7 Bullet Resistance and 400 Environmental Protections, making it capable of surviving in the most hazardous North zones. While its 93 Laceration protection is the lowest in its class, the built-in healing allows the wearer to recover from environmental chip damage and minor mutant encounters more efficiently. It maintains neutral movement speed and a standard hitbox, offering a responsive experience for artifact hunters who value constant regeneration. It is a specialized choice for players who want a "self-healing" explorer build."
