Yuan-ti "Copper Heads"

Physical Description:

The Yuan-ti Copper Head resembles a humanoid figure with serpent-like features, including scales covering its body in earthy tones of copper and brown. Its eyes gleam with a sinister intelligence, and its tongue flicks out like that of a snake, tasting the air for prey. Instead of the traditional Yuan-ti headdress, it wears a wide-brimmed hat adorned with feathers and a snake-shaped buckle on its belt. Its movements are quick and agile, reminiscent of a coiled rattlesnake ready to strike.

Fighting Strategy:

The Yuan-ti Copper Head relies on its keen senses and lightning-fast strikes to overwhelm its opponents. It uses hit-and-run tactics, darting in to deliver venomous bites before retreating to safety. Its cunning intellect allows it to outmaneuver foes and set up ambushes in the wild west landscape.
