Light

Light is a significant weakness for certain creatures, especially those adapted to darkness or nocturnal environments. Exposure to bright or even moderate light sources can weaken them, impairing their senses, slowing movements, or making them vulnerable to attack. This sensitivity often causes creatures to avoid sunlight or artificial lights, forcing them to inhabit shadows or underground realms.

In some cases, light sensitivity includes reactions to specific wavelengths or intensities, with certain creatures only weakened by direct sunlight. As a deterrent, it effectively keeps light-sensitive beings within limited habitats, shaping their behavior around times of natural darkness.
