From 6AM to 12PM, you gain +2 to all SPECIAL stats but from 6PM to 6AM, you suffer -1 to all SPECIAL stats. It is somewhat mitigated by the Night Person perk (resulting in a +1 INT and PER at night), and synergizes extremely well with Solar Powered (+2 Strength while in sunlight).
- Combined with Claustrophobia, being outside from 6AM to 12PM increase each SPECIAL stat by +3, while being inside from 6PM to 6AM reduces each SPECIAL stat by -2.
- Outside of Hardcore Mode, keeping the +2 SPECIAL stat bonuses active is trivially easy, as one can wait until morning in most locations without penalty.
