Etymology[edit | edit source]

Circadian rhythms are physical, mental, and behavioral changes that follow a daily cycle. They respond primarily to light and darkness in an organism's environment.

Trivia[edit | edit source]

  • Circadian Beat appears to be a fusion of the skills Elbow Room and Natural Cover from Fire Emblem Fates, in that offensive and defensive stats are boosted depending on a unit's surroundings, though the trigger here is sunlight rather than terrain.
  • Despite what the cutscene in Chapter 3 of Cindered Shadows may imply, hiding in treelines from the sun does not trigger Circadian Beat in sunny maps.
