Building a shape shifter with interesting rules

[ericthered]

hmmm....

a skill with techniques may work well, I was originally considering a skill per form, but techniques sounds good.

Ok, looking at Morph....

Morph (prep req 10 min -30%, requires sample (bones and hair) -25%, requires skill roll -5%) [40]

I looked up requires sample (I need to learn powers better), and it suggests that monsters that eat the entire subject to reproduce them get -50%. This creature often eats the entire subject (probably for a bonus to skill or a penalty if they don't) but can make do with a complete set of bones, particularly if it has worn them before.

Vertabrate only.... Come to think of it, the issue so much that they can only imitate vertabrates, its that they have a minimum mass and only vertebrates get anywhere near that big. So they have a very loose form of mass conservation, somewhere between a small human and a horse. (they have to get the mass from somewhere though, usually from eating the subject). would this be mitigated mass conservation -10%?

I'd probably give them unkillable I, not unkillable II. Come to think of it, burning damage is also likely to actually kill them. I'd probably also give them fast regeneration vs. things that don't actually kill them. The trick is I need to model breaking their bones, because if you can do that, they are essentially crippled.

Give them a limitation on their regeneration that it does not heal crippling injury.

Any idea what it would be worth?

I'd rule -20%. They aren't 'rare' (-10%) and they aren't quite 'occasional' (-30%) either, so a value in between would be most appropriate.

Yeah -20% is about what I was thinking as well but didnt post as I thought it might be too conservative.

Can they turn into large invertebrates, such as octopus or giant/colossal squids, which can surpass human size? And are they similarly unable to turn into small mammals, whether housecats or Etruscan shrews?

I would say they can function as large invertebrates, though they would have extreme unfamiliarity with the shape at first. They can't imitate small mammals.

Does this mean that if any bones are broken, the creatures don't heal at all, or just that the broken bones don't mend?

the broken bones don't mend. The bones don't belong to the creature at all, they get them from other sources. In fact, the bones don't even have to be "bone", or from a real animal, the creatures can use bones made of wood, stone, or metal. In a high tech setting, I'd let them use plastic. The trick is they can't copy individuals with these bones, and look kind of odd when they use them.

Considering I can take a CT Scan of my head to a 3D printer and get back a 1:1 scale steel of my skull... given enough money... the limitation isn't on the substance so much as the match to the subject. Which would be a function of the skill of the artisan and the technology used to visualize the subject bone(s) - In other words, very much like the imitation requires equipment.

Well, unless having "fake" replacement bones causes disguise penalties for supernatural reasons. I do suspect that most people wouldn't notice you having a fake femur made out of PVC piping unless you cut the length wrong and ended up with mismatched leg lengths... but it's a lot easier to cut it to the right length if you can take the other bone out to measure ;)
