Aquagirl Aquaboy

Aquagirl or Aquaboy is a perk in Fallout 4, Fallout 76, its Nuclear Winter mode, and Fallout: The Roleplaying Game.

Fallout 4

Fallout 76


The perk grants some of the benefits (namely 100% Radiation Resistance and underwater breathing) as the one for Fallout 4; however, it is limited to one rank and does not offer the benefit of becoming undetectable while being submerged.

Fallout: The Roleplaying Game
