Fallout 3 and Fallout: New Vegas
A single rank perk, granting a bonus to Strength and health regeneration while being outdoors during daytime. The perk has the same requirements in both games. The Fallout: New Vegas version was patched at one point to grant improved regeneration.
The perk was expanded to three ranks and altered in its functionality. The first rank grants a bonus to Endurance and Strength, with subsequent ranks allowing radiation damage and hit points to slowly regenerate. Like in the previous two games, it only functions during daytime and not inside interior cells.
Like in Fallout 4, the perk has three ranks, with each rank granting +1 to Endurance and Strength during daytime hours and while being outdoors. It no longer slowly heals radiation damage and hit points, these effects are handled by the Photosynthetic and Sun Kissed perks instead.
