“Robot” is a special subtype that can be applied to any construct without changing its CR. Robots share some features with clockwork constructs, and as with clockworks, you can simply remove the robot subtype and its traits to transform it into a typical construct animated by magic. A construct cannot possess both the robot and the clockwork subtypes. All robots gain the following traits, unless noted otherwise.
Intelligent: Robots are intelligent, and thus have skills and feats as appropriate for their Hit Dice. Unless otherwise indicated for a specific robot, all robots have Intelligence scores of 10. The following are class skills for robots: Climb, Disable Device, Fly, Knowledge (all), Linguistics, Perception, and Sense Motive.
Vulnerable to Critical Hits: Whenever a robot takes extra damage from a critical hit, it must make a DC 15 Fortitude save to avoid being stunned for 1 round. If it makes a successful saving throw, it is staggered for 1 round. The robot remains immune to other sources of the stunned condition.
Vulnerable to Electricity: Robots take 150% as much damage as normal from electricity attacks, unless they are immune to electricity via other special defenses.
Difficult to Create: Robots are crafted via complex methods hidden and well guarded in Numerian ruins or other technological bastions. While the Technic League has developed magical solutions to some of these requirements, actual details on creating robots are beyond the scope of this book.
