Falling Crush (Ex)

If a keeper robot is at least 20 feet directly above any number of Medium or smaller creatures in a 10-foot square (usually due to its spider climb ability), it can release its grip on the surface as a move action and fall onto those creatures. The keeper robot takes falling damage as normal, but each creature it falls on takes 13d6+29 bludgeoning damage and is pinned. Each crushed target can attempt to escape the pin as normal on its turn, and the pin ends automatically if the keeper robot moves off the target’s square. A target of falling crush can’t take the falling crush damage more than once, unless the keeper robot moves fully off that creature and then falls on it again.

Nanite Repair (Ex)

A keeper robot’s nanites heal it, restoring a number of Hit Points per hour equal to its CR. Once per day as a full action, the robot can regain 12d8 Hit Points.

Redirect Power (Ex)

A keeper robot can leech power from nearby batteries to recharge its own weapon or unleash the stolen electricity at its foes. A keeper robot can activate this ability once every 1d4 rounds as a full action; when it does, each battery within 30 feet of the robot (excluding the one in its own weapon) loses 2d4 charges. The keeper robot can redirect this power to recharge the battery in its integrated weapon with the same number of charges. Alternatively, the keeper robot can amplify this power, releasing it in a weaponized arc of electricity, dealing 19d6 electricity damage in a 40-foot cone (Reflex DC 23 half).


Environment any land
Organization solitary

One of the many functions robots can serve is protection, whether for a single person or a large property.

Several robot models have been created for just this purpose. Guardian robots have become something of a status symbol among business leaders and politicians, and a whole range of defense-focused robotic bodyguards of all shapes and sizes are available.

Most guardian robots are crafted to appear as unassuming humanoids of a certain species and usually have a quiet and deferential virtual intelligence. They constantly scan for potential nearby threats and endeavor to stay close to their handlers, engaging opponents from a distance using grenades or weighted nets.

The desire to create autonomous defensive constructs can sometimes lead to unfortunate results, however, especially when time or a natural disaster alters a robot’s programming.

A collection of massive drones known as keeper robots stalk the wild and forgotten areas seeking to destroy intruders, their original directives clearly corrupted into a surprising ferocity. Usually nonhumanoid in appearance, keeper robots are dangerous and implacable opponents. Some stand about 14 feet high on eight legs and weigh several tons.
