An assembled boss-monster requires one hundred pairs and one each of a fur, set of horns, ear, eye, heart, rib, fillet, paw, hoof, and tail. The lab can only store one of each part at a time. A hero can discard a part from the lab at a cost of 50% godpower.

Parts from an explosive boss-monster are not usable (or capable of being placed) in the lab, e.g. shreds of the boss monster.
As with everything in (artificial) life, the better the ingredients, the better the result. In other words, the more abilities the defeated boss-monster possesses, the better the “donor” part. Three ability parts are only available from boss-monsters that guard dungeon treasure. Treasure bosses have been know to drop more than one part. A boss-monster uncovered by digging, even if it has three abilities, will only yield a two ability part at best. Also, more parts from the same defeated boss-monster will increase the created boss’ power along with influencing the name of the assembled boss-monster.
Once a hero gathers a full set of parts, the Lab will display the potential assembled boss-monster’s estimated power level and provide the god with the option to awaken that boss-monster.
The estimated power of the boss-monster is calculated as follows:
- Each 3 ability (3 ab) part adds 21% power
- Each 2 ability (2 ab) part adds 11% power
- Each 1 ability (1 ab) part adds 1% power
- Each additional part from the most common boss-monster in the lab adds 10% power (e.g. if a lab has two parts from the same boss-monster and eight parts from eight other boss-monsters, there will be an additional 10% power and a lab with three parts from the same boss-monster and seven parts from other boss-monsters will add an additional 20% power)
- Each additional part from a boss-monster that is not the most common boss-monster in the lab will add 1% power (e.g. if a lab has four parts from an Ark Enemy, three parts from a Obscentinel, and two parts from a Stalactitan, the additional power will be +30% (from the Ark Enemy since it is the most common boss-monster in the lab) +2% (from the Obscentinel parts) and +1% (from the Stalactitan parts).
Gods often wonder how many treasure bosses must be defeated to obtain ten different 3 ability parts. Answer: on average, thirty. This is explained by the coupon collector problem. Note: this answer assumes the following:
- The hero obtains a part from each treasure boss fight;
- The probability of obtaining each part is equal;
- The hero will not "lose" the part before placing it in the lab; and
- None of the boss-monsters fought are explosive, since explosive bosses do not drop usable parts (note that the probability a treasure boss has an explosive ability is 18.75%)
Also note that thirty is simply an average number. A hero could defeat as few as ten treasure bosses to obtain ten different parts or could defeat an infinite number and still not obtain ten different parts.
