** Assumes creature is as dense as a regular animal. Constructs of denser materials will weigh more.
A construct can be made with a core of one material, but an outer layer of another. While this will not be apparent under normal circumstances, if the construct is significantly damaged the inner layer will show through. Layering is done thusly:
One-half distribution: A construct can be made using two different materials in equal proportions.
* Weight modifier: Add the weight modifiers of both materials and divide by half (rounding up), then apply this number to find the correct weight range.
* Price: Divide the weight of the construct in half. Half of the price will cost the rate of the first material, and the other half of the price will cost the rate for the second material.
* Hardness: Hardness ratings are also added together and divided by half (this time rounding down) to determine the total hardness.
Example: A Small construct made of marble and silver has a total weight modifier of 4+2=6, divided by 2=3. Thus, a minimum of 24 pounds will be needed to make a Small construct with these materials. 12 pounds will be marble and will cost 240 gold pieces. 12 pounds will be silver and will cost 60 gold pieces; the materials will cost 300 gold pieces total.
Three-fourths distribution: A construct can also be made so that most of it is made of one material, while only one layer is made of another substance. This is often done so that the construct is pleasing to the eyes, with a brilliant surface layer over a cheaper, coarser core of material.
* Weight modifier: Choose which material is going to make up the bulk of the construct. The weight modifier for the bulk material is multiplied by 3/4. The weight modifier for the fine layer of material is multiplied by 1/4. Both results should be rounded up and then added together for the total weight modifier.
* Price: Apply the adjusted weight modifier to determine how much material must be purchased to make a construct of the desired size. The bulk material will make up 3/4 of the weight, rounded up, and the price should be decided accordingly. The fine layer material will make up 1/4 of the weight, also rounded up. Add the two prices together for the total price.
* Hardness: The hardness rating of the bulk material is multiplied by 3/4, rounded down. The hardness of the fine layer material is multiplied by 1/4, also rounded down. Add the results together for the total hardness rating.
Example: A Small construct with a bulk layer of mud and a fine layer of marble has a total weight modifier of 0+1=1 (mud has no weight modifier, and marble’s x4 is multiplied by 1/4). The marble layer is not thick enough to make the construct noticeably heavier. For an 8 pound construct layered in this way, 6 pounds will be mud and 2 pounds will be marble, costing 6 gold pieces and 40 gold pieces, respectively. The total price is 46 gold pieces. Mud has no hardness rating, and the marble layer is too thin to warrant its full hardness rating of 8. This is multiplied by 1/4, for a total hardness rating of 2.
Any sort of construct can be created with a hollow section, regardless of size or layering. A hollow space is necessary in order to purchase the swallow whole ability found in Step 10. Only a “stomach” area in the torso of a construct can be hollowed out; limbs are not left hollow because of concerns about effectiveness and stability. A hollow tube can be created so that the construct can swallow targets into the belly area, or a “door” leading into the hollowed space can be created, but it will need to have a lock affixed to the outside to keep it shut. It is important to note that there is no naturally occurring acid in a construct’s “belly.” Acid can be placed inside a construct but it will eat through the construct’s materials unless the material of the “stomach” is strong enough to resist the effects. The material of the “stomach” must have a hardness rating that is greater than the acid’s direct damage.
A hollow stomach reduces the total material cost and weight by 10%. It also reduces the construct’s overall hardness rating by 10% (round up, minimum of 1).
Each hollow construct can hold a number of creatures in its “belly,” depending on the construct’s size. See Table 6 below.

Constructs are not created with any hit dice, so every hit die must be purchased. The rate for purchasing hit die is the number of hit dice squared x 50 gp. Please see the Table 7 below for hit die requirements as related to size; smaller constructs cannot have as many hit die, while larger constructs must have more to start with. Constructs use d10s for hit dice.

The base attack bonus of a construct is always 0.75 of its total hit dice rounded down (advancing like the cleric class progression). The saving throw of a construct is also based on their hit dice. They get no good saving throw and advance like the cleric class. Thus, when you purchase hit dice you are actually purchasing other benefits as well.
A construct’s base statistics are determined through their size. A construct does not have a Constitution score and cannot gain one. A construct does not start out with an Intelligence score, either; every Intelligence point must be bought. The base statistics granted by each size category are given in Table 3 below:

A construct’s base statistics can be raised so that it possesses intelligence or has higher scores. A construct cannot exceed the limits of its size during creation, however. These limits can be found in Table 8 below:

To raise a construct’s statistics from a score of 1 through a score of 15, apply the following formula: (base rating – desired rating) squared x 100 gp. For example: to raise a base stat from a 5 to a 10, the formula would be: (5-10)2=25x100 gp=2500 gp total.
To raise a construct’s statistics above a rating of 15, apply this formula: (current rating – desired rating) squared x 200 gp.
A construct with no Intelligence score cannot have skill points or buy ranks in a skill. If the construct does have an Intelligence score, one can purchase skill points for it at the rate of 50 gold pieces per point. In order to buy ranks in a skill, the construct must have a minimum score of 2 in the skill’s related ability (for instance: in order to buy ranks in Climb, the construct must at least have a Strength score of 2).
Magical items that grant skill bonuses can be specially made and embedded into any construct, even if they have no Intelligence score or skill points. The formula to create a skill enhancing item is: bonus squared x 20 gp.
The saving throws of constructs can be enhanced by the addition of magical items that boost saving throws. The formula to create an item that grants saving throw bonuses is: bonus squared x 1000 gp (as per a Cloak of Resistance). As another option, a magical item can be added that grants a bonus versus one type of saving throw, like a Periapt of Poison. The formula to create an item that grants a bonus versus one type of save is: bonus squared x 250 gp. These are not typical magical items made for character use; they are simply enchanted stones meant to be placed inside a construct. If the construct is destroyed and a magical stone is left intact, it can be set into jewelry or other items and worn, granting its bonuses to the wearer.
Constructs generally come with five limbs and a main body. Humanoid-shaped constructs typically have a head, two arms, two legs, and a main body. Quadrupeds have four legs, a head, and a main body. One additional limb can be added per hit die, and each additional limb must be purchased as per the prices in Table 9 below. Each limb of a construct can be imbued to attack in a specific way.

* Additional limbs do not come with functional attacks; extra attacks must be purchased separately.
All constructs gain a slam attack for free, which does damage according to Table 11. All other attack forms must be purchased for the rates in Table 10. For each attack form purchased, the construct is considered to be proficient with that attack and with the limb required. If a construct is created with a man-made weapon, it is considered proficient with that particular weapon only, but not with all weapons of the same type. However, if the construct has an Intelligence score of 5 or greater, then it is considered proficient with all weapons of that kind (all long swords, for example, not just the one it was made with).
