Hagalaz rests in the shallows of a hidden lake deep in the forest at night. Though he is typically more active during the night hours, there are moments he will just sleep an entire day away to regain the energy he needs to Gigantimax.

The water more so helps calm and soothe his aching joints when he sleeps.
