Table: Construct Size and Bonus Hit Points
Construct Size Bonus Hit Points
A construct is an animated object or artificially created creature.
A construct has the following features.
d10 Hit Die.
Base attack bonus equal to total Hit Dice (fast progression).
No good saving throws.
Skill points equal to 2 + Int modifier (minimum 1) per Hit Die. However, most constructs are mindless and gain no skill points or feats.
Constructs do not have any class skills, regardless of their Intelligence scores.
Traits: A construct possesses the following traits (unless otherwise noted in a creature's entry).
No Constitution score. Any DCs or other Statistics that rely on a Constitution score treat a construct as having a score of 10 (no bonus or penalty).
Darkvision 60 feet.
Immunity to all mind-affecting effects (charms, compulsions, morale effects, patterns, and phantasms).
Immunity to bleed, disease, death effects, necromancy effects, paralysis, poison, sleep effects, and stunning.
Cannot heal damage on its own, but often can be repaired via exposure to a certain kind of effect (see the creature's description for details) or through the use of the Craft Construct feat. Constructs can also be healed through spells such as make whole. A construct with the fast healing special quality still benefits from that quality.
Not subject to ability damage, ability drain, fatigue, exhaustion, energy drain, or nonlethal damage.
Immunity to any effect that requires a Fortitude save (unless the effect also works on objects, or is harmless).
Not at risk of death from massive damage. Immediately destroyed when reduced to 0 hit points or less.
A construct cannot be raised or resurrected.
A construct is hard to destroy, and gains bonus hit points based on size, as shown on the following table.
Proficient with its natural weapons only, unless generally humanoid in form, in which case proficient with any weapon mentioned in its entry.
Proficient with no armor.
Constructs do not breathe, eat, or sleep.
The Robot Subtype
"Robot" is a special subtype that can be applied to any construct
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 Culture.
robots utilize these technological arms and tools themselves. A robot's weapons and defenses are fueled by its central energy core, and unless otherwise indicated, a robot's weapons and defenses have infinite ammunition and power.
Force Fields A force field sheathes a robot in a thin layer of shimmering energy that grants a number of bonus hit points that varies according to the robot (typically 5 x the robot's CR). All damage dealt to a robot with an active force field is reduced from these hit points first. As long as the force field is active, the robot is immune to critical hits. A force field has fast healing equal to the robot's CR, but once its hit points are reduced to 0, the force field shuts down and does not reactivate for 24 hours.
Integrated Weaponry A robot that has a technological weapon (such as a laser rifle or chain gun) built into its body treats such weapons as natural attacks and not manufactured weapons attacks, and cannot make iterative attacks with these weapons. Integrated weaponry can still be targeted by effects that target manufactured weapons (such as magic weapon spells or sunder attempts), but as a general rule cannot be harvested for use outside of the robot's body once the robot is destroyed. A robot is always proficient with its integrated weapons. Integrated ranged weapons do not provoke attacks of opportunity when fired in melee combat.
