Aswangs are sensitive to bright light and loud noise. When an aswang takes radiant or thunder damage, they must succeed on a DC 11 Wisdom saving throw or become frightened for 1 round. In addition, they have disadvantage on saving throws against effects that cause deafness due to loud noise or blindness due to bright light, and Charisma (Intimidation) checks against them have advantage if the aswang is in an area of bright light or in a noisy area (GM's discretion).
