Monstrous Physique


Rules Questions


Pathfinder Adventure Path Subscriber

Running RotRl, my magus player asked about finding pieces of monstrous humanoids to use for Monstrous Physique. I've already explained to him that he would be able to find some pieces in a city, but probably at a noticeable price. Is there some sort of guide for this? My plan is to read through his wish list, determine how rare the creature is, decide as to whether or not he could find that in a city nearby, and determine a price. My big issue is determining some sort of baseline to use for a price, whether it is x gold per CR or something else I'm overlooking. Thanks for any input anyone can give.

I think the closest you can get is the rules for making trophies. Or he takes Eschew Materials since the piece have no price so are less than 1gp.

If they don't list a price in the spell description its assumed they're included in the spell component pouch. going further than that is going to add an unfortunate level of bookkeeping to the game.

The reason I'm trying to come up with a price is that, while we are playing with a house rule of Eschew Materials in effect, the pieces of higher CR monsters would definitely be worth money on the magical market. We're fairly laid back with RAW and RAI because we meet maybe once a week for a couple hours.
He researched Monstrous Physique and wants to use that with his character. He recognizes and understands that the monsters he has on his wish list are fairly rare and dangerous to kill. By attaching a price, it keeps the game fairly realistic (you all know what I mean by this) I was just curious if anyone else knows of resources to help ascertain prices.


In terms of game balance they're not supposed to cost anything.

In terms of realism it's totally up to you, depending on your world.

I'd probably look at knowledge DCs to identify the monster as a guide (10+CR for most monsters, but 5+CR for common monsters or 15+CR for rare monsters). If you want it to be more expensive than that you could multiply the total by 5 or 10 ((10+CR)×5), or just change the "+" into a "×" (10×CR).

This is all totally home-brew and it's making this particular spell less powerful than it would be. Also if he has Eschew Materials he can bypass the whole thing, so ...

there aren't really any official ones....the trophy ones brush against the edges but thats more like minor magic item creation than spell components. You'll have to homebrew a system if you want that kind of depth.


I suggest don't put price to this material this is something that only cults, academy or similar have.

Because when adventure kill a creature it's take only what have value

I suggest that if he is in an academy the will give to him for free, wandering spellcaster may have and cults like baphoment is to kill and take

Actually, if you want to make it a thing...make it a focus instead of a material component. Have it be a rune scribed bone from the monster...then you can set a price based on CR or whatever metric, Bookkeeping is limited to a list of forms the character can take, the spell gets less nerfed and you now have minor side quest fodder for daaaaaaaays.

Consider this idea stolen. I mean, inspiration drawn!

As far as the worry about bookkeeping, we take the approach of asking DM if something vaguely rare/expensive is found in town/city. He was reading up on the spell and its potential uses. He was wondering how he might be able to utilize it in this game, as I have warned them several times that this adventure gets harder and harder. Because we don't play often/long, we tend to handwave minor stuff ("did everyone get their shopping done in Magnimar?") and focus on the core of the adventure. Group is happy, I'm happy, it all works.

Hmmm... I like where this is going... although the monsters on his wishlisy are fairly high CR, so I may go as high as 100g x CR. Makes it expensive enough to be a noticeable purchase without being so overly priced that he can't effectively use the spell. Keep in mind, his wishlist is the equivalent of of a man in the US wanting food from a nation on the other side of the world. Bad comparison, but the point is transport of said items would still be expensive.

Believe it or not, this response really helped with coming up with a price. I thank you greatly and kindly, fair one.


Haha no worries.

I really like Ryan Freire's idea to make them Focus components too. I think combining that with the 50×CR cost (or whatever) makes it fun and thematic without the spell losing it's appeal.

The problem is that if the cost it's 50-100g x cr for this spell I prefer to cast limited wish that only cost a diamond 1500g

Instead put the cost in silver and whit a max of less of 10g


Grglspyzx wrote:

Let me guess, CR 18, or maybe even CR 27? If they aren't top of the player's wishlist, they should be, as there is nothing that comes even close to them for combat power.

If you want to make higher CRs more expensive, consider a quadratic progression instead of a linear one. Something like 5gp*CR².

Limited Wish has a material component, meaning the diamond is gone after use. Ryan Freire and MrCharisma talk about focus components, meaning they're not spend upon casting the spell.

And going your route men that we have an unlimited number of pieces of extremely rare creatures in that spellpouch.

I prefer the bookeping.
Pieces of a popobala (a CR 15 monstrous humanoid) aren't available at every street corner.

I totally disagree, not listing prices because it would require to specify them for every monster ever created, plus every monster a GM could make isn't the same thing as saying that they have a negligible cost.

Yeah the actual numbers weren't researched at all, it was just an idea. I do like Derklord's "Xgp*CR²" idea. It follows the same rules for increasingly powerful magic weapons/armour/etc. I don't know exactly what the multiplier would be, but that seems like the best fit.

That's how the rules are written:

Material (M): A material component consists of one or more physical substances or objects that are annihilated by the spell energies in the casting process. Unless a cost is given for a material component, the cost is negligible. Don’t bother to keep track of material components with negligible cost. Assume you have all you need as long as you have your spell component pouch.

Having said that, I don't mind this rule. I really like the Focus Component idea, and having it either cost money or require you to kill one means you can either spend time or money to prepare for the spell.

We did that with the Robe of components. We said that it was needed to "teach" it once what components are needed for the spells we are capable to cast storing them in the vest while memorizing the spell. Each different form we could get from polymorph spells was treated as a different spell. The component where consumed when used to teach a new spell to the Robe.


The part of put in the material to focus it's not so great because you will put a good spell in constant use and not only monster physique, it's mean that will apply also to form of the dragon undead anatomy and the insect spell


I don’t think cost should be based on CR at all, but on rarity. It’s not like the best choices for polymorph are often the highest CR anyway. You should read the polymorphamory guide.


Right, but the problem with that is there isn't much of a guide for how rare they are, so the GM has to come up with a list of everything, or make an improvised judgement call every time the player wants to Polymorph into something new (and has to remember what calls they made before).

Basing it on CR will give a vaguely balanced cost and gives you a definitive cost that you don't have to look up every time.

It also adds some moral hazard to the spell. Hows the pc going to get a bone from nonevil versions of sentient/intelligent monstrous humanoids. Does their faith permit grave robbing?

1. I 100% agree with changing them from components to focus. Components = bookkeeping nightmare. Focus is a fun way for the PC to unlock new options.
2. Guides on polymorph also discuss optional rules to know about the creatures in polymorph spells. Learning about the creature might require some sort of check (knowledge or spellcraft or arcana or gather informaiton)? Consider adding that. If you do, knowing the perfect creature becomes part of the challenge, and it will allow you to drastically reduce the cost of the components...it's not about affording it, it's about knowing what to ask for.
3. I also like availabilitypricing on rarity, not CR. It's not perfect, but if you want to apply a simple, non-subjective symptom, consider...

In a large town (% = percent chance available; gp cost of focus)
Monster from Bestiary 1: 60% of being in stock; 1 gp
Bestiary 2: 50%; 2 gp
Bestiary 3: 40%; 4 gp
Bestiary 4: 30%; 9 gp
Bestiary 5: 20%; 18 gp
Bestiary 6: 10%; 36 gp

Then, you can modify availability chances for town size:
Small Town: -10 percentage points
Village: -20
Hamlet: -30
Thorp: -40

Small City: +10
Large City: +20
Metropolis: +30

That's good if your party travels from place to place. If your adventure occurs in a single location or has little travel, consider allowing a new check 1/month as the curiosity shops refresh their options.

Finally, if you do something like this I recommend doing it for all polymorph spells, not just monstrous physique.

So in this system your player 1) rolls to see if he knows the creature is a good option (e.g., a knowledge skill), asks you if it is available, so you roll availability based on the bestiary, and finally, he pays the fee and then has the focus forever. In this way

I'd also let the player re-roll the skill to know about the creature every time he improves the knowledge skill ... but that's another story because you didn't exactly ask about knowledge skills.
