The demon-flesh samples used to grow vatlings are contained in specially-constructed zinc cylinders that stabilize the tissues for long-term storage. They're expensive to create and feed, so mostly sorcerers make do with a handful of strains, but if a new mutation is particularly useful it can be tempting to add to your repertoire.
When finding a new tissue sample (from another sorcerer), roll random characteristics for the fleshy shells that strain creates (or just make something up):
|3 – 5||Budding (asexual)|
Abilities (2/6th chance of one):
|1||Fast maturation (half growth time)|
|2||Armored skin (+2 AC/Armor)|
|3||Allergic to gold|
|4||Burns in daylight|
|5||Sees in dark|
|6||Rubbery skin (+1 AC/Armor)|
|11 – 12||Stable (half chance of physical mutations when reproducing)|
|2||chartreuse||skinny||one small horn|
|3||orange||medium||two small horns|
|5||purple||fat||two long horns|
|6||blue||obese||two imposing horns|
When a strain is used to create a new body, roll 1d8 to see if it mutates:
1 Change method of reproduction
2-3 Add random ability
4-5 Lose random ability
6-8 No change
And move two of the appearance categories one notch.
|It brought you flowers?|
|Vatlings get cold too|
Base 50 gp * spell level
Size: 1.5' tall and 1 HD per spell level
Lifespan: 3 hrs / 3 days / 3 weeks / 3 months / 3 years / 3 decades / 3 centuries
Cost doubles each category you go up in lifespan
Time to create: spell level number of days, doubles at each lifespan category
Takes twice as long without a proper lab
For each offspring you induce it to create pay the material cost again.
Reproduction is triggered by introducing certain chemicals to the mixture, they don't just start budding while walking down the street.
|The smarmiest vatling|
A body for a level 3 spell that will last 3 months would cost 50 * 3 * 2 * 2 * 2 = 1,200 GP and 24 days to grow. It'd be 4.5' tall and HD 3.

They can cast themselves once per day.
They get personalities over time, but start off automaton-like.
Their appearance is rapidly modified by whatever spell they contain (smoking coal-mouths for fireball, etc).
New ones don't automatically like you! Do a reaction roll with your level - their level as a modifier. Bad reaction rolls result in them trying to escape or murder you.
