Shield guardians were powerful constructs created by skilled Spellcasters, typically to serve as protectors. Each guardian was bound to an amulet, which allowed its master to issue commands and control its actions from a distance. These constructs were typically assigned to guard important individuals, locations, or treasures, remaining still and silent until a threat presented itself. Once activated, a shield guardian pursued its master's directives with unwavering loyalty and efficiency.
They stood over ten feet tall and were crafted from metal and stone, with a broad frame designed to endure heavy punishment. In combat, shield guardians could absorb damage meant for their master and even regenerate over time, making them exceptionally durable. They also retained a stored spell within their structure, which they could release when directed by the amulet bearer. Despite their limited intelligence, shield guardians performed their duties with precision, following orders exactly as given without deviation.
