"Big Spot"
The automaton known as "Big Spot" was built to be an exceptionally strong and sturdy (if not particularly fast) 'construct of burden.' Loads that would crush an ordinary pack animal can be lifted with ease by this gentle steel brute.
While not explicitly designed for combat, Big Spot's narrow, spike-like metal feet can be lethal if used to trample a prone assailant. For this reason, in the event of an attack, the construct is programmed to attempt to topple aggressors, allowing it to then impale them if there are no immediate means of escape.

Control Talisman. In addition to having its own simple intelligence, Big Spot can be controlled by means of a unique talisman. A creature holding this talisman can, at the start of its turn, use its action to activate the talisman, assuming direct control of Big Spot, and perceiving through its senses until the start of that
creature's next turn, when it can choose to continue using the talisman the same way. During this time, the creature controlling Big Spot is deaf and blind with regard to its own senses.
Construct of Burden. Big Spot is considered to be a Huge creature for the purpose of determining its carrying capacity.
Magic Resistance. Big Spot has advantage on saving throws against spells and other magical effects.
Variable Illumination. Big Spot can shed bright light in a 10- to 60-foot cone and dim light for an additional number of feet equal to the chosen range. Big Spot can enable, disable, or alter the range of this light as a bonus action.
