ridged coiled
Horn
Coiled: Coiled horns causes the horns to be so curved that they coil around themselves into spirals.
Ridged: Ridged horns are more textured, scale-like or with small spikes. Ridged horns can be partially smooth or twirled, but must have some ridged texture present. If spines/spikes are present they must not be too tall and may not be confused for spined horns.
You're always welcome to draw your own horns, the examples below are intended as inspiration and to show some different ways ridged coiled horns can look.
