Setting DCs for Knowledge checks regarding creatures.


Pathfinder First Edition General Discussion


I'm not sure if anybody's actually taken a stab at doing this (if so, please tell me so I don't waste a god awful amount of time on this project), but I'm planning on setting up a system for use in my group (and anybody else who wants to use the system) that functions similarly to how knowledge checks for monsters are treated in 4e.

Basically to identify a monster's "abilities and weaknesses" the DC is 10+creature's CR. (or 5/15+creature's CR, depending on the creature) Doing so reveals one piece of information. But the question is. What should the first piece of information reveal? Second? Third?

I was hoping to find some help establishing in which order that information about monsters should be uncovered. And what information should be grouped together.

Information revealed could include:

How many natural attacks the creature has, and what it's reach is.
What types of senses it has.
Ect.

Any suggestions and thoughts on this matter would be much appreciated.

well 4winds fantasy came out with its monster knowledge cards a while back. Though that is based on the core rules dcs but it might give you a good starting point for your rules.


Do you know of any sites where I could find a few sample cards? I don't necessarily wish to BUY the product, but seeing how they format and prioritize their questions WOULD be a big help, I'm sure.

I do believe it is closed content so I dont know of anywhere that has their material other then purchasing the pdfs.


I see, well I'll put it on my 'to buy' list, for now. Do you know if it covers every monster in both bestiaries?

To be honest basing the check DC on the CR has always seemed askew to me. Think about a big red dragon. Your average peasant has never seen one but he knows it's gargantuan/colossal, flies, breathes fire that does a lot of damage, and has a lot of gold hidden under a mountain somewhere. Ditto vampire, giants, etc.

Now think about about some obscure CR 1-2 monster from Bestiary 2. As an experienced DM I'd be likely to say "a what?"

I think this is a situation where trying to make rules to quantify what players know about a monster on a case by case basis is making things more complicated than they need to be. You're the DM, you should know the monster fairly well. Just make a judgment call based on the player's knowledge check and the rarity of the monster, how much the pc has encountered similar monsters etc, and reveal what you think is appropriate.

Even if you could make a fair and more complete system for this type of knowledge check it would only be a rough guide at best. There's something missing with a lot of 3.5+ DM'ing and IMO it's this: let the DM make a ruling and get on with it.

I've always treated this like a Bluff/Diplomacy check where I'm the intended target. Is the result high enough to convince me they know what they're after?

Not very formulaic, I know, but still.

Color me confused, since that's exactly how the core Pathfinder Knowledge skills work.

Base DC = 10 + CR; if you make that, you identify the monster and get the Type, Subtype, and other basics.
DC is 5 + CR for common creatures (Goblins is the example used), while a DC of 15 + CR is suitable for more uncommon creatures (Tarrasque, I think, was the example).

For each 5 over the base DC in your check, you get another piece of information.

Where the core mechanics break down is exactly what you are asking for ... what is the baseline information and what is useful information to give for each additional 5 over the DC?

My baseline: Name, Type, Subtype, natural attacks (Claw, Bite, etc.)

Additional information (1 per 5 over the DC):
Senses
Special Attack #1 (Poison/Grab/Swallow Whole)
Defenses: DR
Special Attack #2
Defenses: SR
Defenses: Resistances
Defenses: Immunities
Special Attack #3
Defenses: Other (Auras, etc.)
Vulnerabilty #1
Vulnerabilit #2

Since that requires a result of up to 55 over the base DC, you can condense:

Base : Type, SubType, Name, Natural Attacks, Senses
Base + 5: Special Attacks (Poison, Grab, Swallow, etc.)
Base + 10: Defenses (DR, SR, Resistances or Immunites, Auras)
Base + 15: Vulnerabilities

This last breakout is be more than "1 useful piece of information" at a time, but it may also be more practical.


We keep it simple and let the players ask questions. Does it have DR/Cold Iron? Does it have fire resistance? Does it have Spell Resistance? Blindsense? Can it swallow whole? Does it have reach? Can it cast spells? Yes or no questions only. One question for the DC and 1 additional question for each 5 points over the DC. Sometimes it's frustrating to ask if it has DR and the answer is yes, but not know what type. But if you have a high enough roll you can see if it has a specific DR. Since most of the time players are looking for certain resistances or immunities, once they find out that the creature isn't resistant to their specific attack preference, they're happy.


I like the way Urath broke it down for me, I think I can work with that system... with a few personal modifications.

The problem I have with letting the players ask the questions is that... a clever player can get what they need to know at a base+5. I like to have it so they roll a knowledge check and I say, 'this is what you know.... ect.' The higher the knowledge check, the more useful the information.

Thank you for the imput, I think I can work with this.
