Monster Knowledge ck for a Daemon

[Stephen Ede]

The party is likely to fight a boosted Piscodaemon CR13 and I was looking at what information I should give them on Knowledge Cks.I used to give them virtual Stat blocks information but on further reading it suggests much vaguer information.

So I'm looking at the following pieces of information
a) It is highly perception with special abilities of detection (Dark Vision, See Invisibility, Detect Good, Detect Magic)

b) It's significantly resistant - (DR 10/Good, Immune Acid, Poison, Death effects, Disease, 10 Resist Cold, Electricity, Fire, SR 24)
b1) Adding that it's immune to Acid and poison to a higher check ability.

c) Con Poison, Weak but difficult (1d2 Con + Staggered, 6 rds - DC25 2 consecutive saves)

d) Some of them are fearsome Grapplers (I've done a feat rebuild + 2 Monk Levels to make it a Grapple Monster).

I was wondering what order I should put these bits of information in in terms of basic success to DC + 15.
What do people think?
Thanks

Let the players ask for the info they want, do you want to know defensive abilities or offensive, because the knowledge the characters have should be relevant to what they need to know because it was that character that remembered it.

A wizard isn't going to retain that something has DR if it also has SR and elemental resistances, for example.

Forgot to mention another tidbit -

e) Can Dispel Magic at Will and cast Fly and Stinking Cloud (Spell-like Abilities (At will) dispel magic
Spell-like Abilities (3/day) 3rd DC (18) fly, stinking cloud)

Memory is a tricky thing.

People note down what interested them at the time. So your Wizard might be reading and thinking "wow, this thing is resistant to everything" rather than "Hmm, he's resistant to the energy attacks I use".
Keep in mind this is someone who works with a party so is going to consider the strengths and weaknesses of the other party members and not just him self.

Hence I said what the player wants or did you not bother to read the first sentence?

If the wizard thought that whatever said thing is, having a particular DR was more useful than knowing it had SR because the wizard has mostly conjuration spells with no SR then he would remember th DR so the fighter could pick the right weapon.

Knowledge skills are supposed to help the players to win encounters by having USEFUL information not random crap unrelated to what they need to know, I've seen too many DMs try to f&*# players over and make knowledge skills uselsss because 'memory is a tricky thing' translation 'that skills is useless because I say so'.
