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, control its actions from a distance, and even transfer damage down to the user into the shield guardian itself. These constructs were typically assigned to guard important individuals, locations, or treasures, remaining still and silent until a threat was presented. Once activated, a shield guardian pursued its master's directives with unwavering loyalty and efficiency.
They typically 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.
