This skill is used to assemble robotic NPC allies from appropriate components. Using this skill will use up some Mental Points. You can use the skill at any time; you will be prompted to select up to ten items to use to build the robot. Sturdy items will make the robot stronger, armor and weapons will be built into the robot, and adding a PCS will make the robot smarter.
The resulting robot will follow you around as a pet, or if all the robot's stats are at least 10, a sentient lancemate.
For details on how to build robots, see Guides:Robotics.
