Hiya!

I pretty much run how [MENTION=9501]Prism[/MENTION] runs it... via player questions/experience and his characters background. If the player can give me a good reason why his Dwarven Champion would have any idea what-so-ever about the sensory capabilities of a Willo-the-Whisp, then I'll allow an INT roll. Otherwise I typically reply with something that any commoner who is "interested in monsters and such" might have come across in books, stories, etc.

Often I always describe the monster unless it's one that everyone at the table would know...and sometimes this works against them. :evilgrin: So I will say "You see a hulking creature emerge from the shadows. It's a full two heads taller than a man, has skin the colour of rotting flesh, and dark, black eyes. It's gangly arms end in elongated fingers tipped with claws as dark as night. It's long, snout-like maw is dripping with blood from it's last meal, of which you see on the ground behind it...a poor, unfortunate orc". It's up to the players to decide if this is a Troll or not. They can just make the assumption, or they can ask for a confirmation roll, so to speak. I'll ask them for their INT adjustment and make the roll for them. Then I describe their resluts "From the looks of it, it fits the description of a troll, other than you've never heard of them being this pasty-green colour...although albino trolls are fairly frequent, this one does have a distinctly green tinge to it" (if he failed by a few points)...or "Yup, sure looks like it. Everything fits what you know of trolls" (if he failed by a lot) ...or "Yes, but it's far worse. You've heard of these...and you're pretty sure it's an undead troll...a horrid mix between a Ghoul and a Troll...this is a Thoul!" (if he succeeded).

I would NEVER let players roll themselves and see their results. Their characters would have no idea at all if they have correctly guessed, remembered, or even heard about something about a creature. If the player sees the results, and sees his 24 total...and I say "Yup, sure looks like a troll...and undead one...a thoul!" the player KNOWS he is correct...as opposed to, well, not.

Then again, I pretty much make all "knowledge" and "uncertain outcome" rolls on behalf of a player then hand out info as appropriate. Like with stealth checks, picking locks, looking for traps, reading languages, etc. Anything where success/failure isn't obvious or binary (e.g., making a to hit roll, save, climbing a wall, etc.). I mean, if everyone searches a room, and nobody rolls higher than a 6, you can bet coppers to platinum that the players will say "We search again" and find some way to justify that search. Luckily for me though, my players just let the dice fall where they may and rarely try and pull those kind of shenanigans. :)

But what are the PCs using to "know"? Is there a bardic lore check, a skill I don't know about?

Each DM will just pick whatever send appropriate. Most likely starting as an Intelligence check, maybe a skill they feel is appropriate to the kind of monster. Or ignoring skills, a DM might let a cleric apply his profiency bonus to checks relating to undead simply because that's typically a thing clerics know about. Same for druids and animals, wizards and constructs perhaps.

So yeah, it's one of them "Rulings not Rules" things.

Fair enough. And of course, if you've had 10 minutes of observing them stealthily, your chances of figuring out what they are will be much greater than if you just run into them around a corner...

Hi all !

When the heroes enter a combat and want to know information about the enemies (keywords, strengths, weaknesses etc) do they have to do the skill-roll as an action or is this a free action ?

It's helpful to think about the fictional action that is taking place rather than the ability check itself. The ability check just resolves the outcome of a fictional action, when said outcome is uncertain. But what are the characters actually doing to get this information? Some might be recalling lore from their studies or experiences. Others might be deducing the monster's strengths and weaknesses by observing how it behaves. (Both of these fictional acts may call for an Intelligence check.) Do these things take an appreciable amount of time when seconds can mean the difference between life and death? As DM, you'll have to decide. And the answer might not always be "Make a skill check as a free action..." or whatever. Sometimes, it might take more time or there might not be a roll at all (because the character succeeds or fails outright). In some cases, failure might cost something like a moment of hesitation that grants advantage to the monster's next attack. Be as consistent as possible when working with substantially similar fictional situations, but I suggest not trying to make a rule to fit all situations equally. Players also have no special right to making an ability check or even to ask for one.

Consider also setting the DC fairly high and making the stakes: (Success) The PCs recall or deduce something really useful e.g. stats/mechanics, special abilities, strengths, weaknesses, resistances, etc and some interesting lore. (Failure) The PCs recall or deduce some interesting lore e.g. cool stuff from the monster entry but not the stat block. "You don't know anything..." is boring.

Finally, I recommend DMs telegraph the special abilities, strengths, and weaknesses of the monsters when describing them. Have the fire-immune creature walk through the campfire like it's not a big deal. Show the assassin killing a victim with a single thrust of a blade. Describe how the troll shies away from the pool of acid. Not only does this make you mindful to make your descriptions cooler, it gives the players valuable information from which to make decisions. If they're paying attention and making good choices, they can get an edge without needing to ask to make checks.

As a free action I allow my PCs to know the following about the creatures they face, without a skill check:

  • The size of the monster
  • The color of the monster
  • The aroma, if any, the monster exudes
  • The relative level of hirsuteness of the monster
  • Whether that monster is speaking to them in a language they understand
  • Whether the monster appears to be brandishing something heavy or sharp at them

Beyond these features, my players enjoy the skill "hindsight" to inform them of the monster's qualities.

:-D

Thank you all for the useful informations ! Seems as there are many ways to handle that subject. :)

I think I will go with free action, but only if the character has proficiency in that skill.

If it is the first time a character encounters a creature, he/she can't know anything unless it has previous experience with the type of monster.
But during a combat, I do allow a character to make a free perception check to see if certain damage is very or not effective.

When the characters encounter a similar creature it has become common knowledge.

Although it is very hard for players not to meta-think, let them know that there is a difference in player knowledge and character knowledge.

We don't do it with lore rolls. To my mind, it's better to let each player decide what his character knows because it's part of what makes their characters what they are. Also, if the DM uses custom monsters, the players are best placed to do this fairly because they don't know what they are facing, whereas the DM does.

Faced with a tall, horrible-looking humanoid with rubbery grey knobbly skin, Elword cast Chill Touch and shouted to his companions "Troll! Hit it quick while it can't regenerate!"

The monster opened its ghastly maw and laughed. "Foolish wizardling, my kind are not affected by your puny cantrips!" and struck a backhand blow with its arm that sent Elword's staff flying, to land with a clatter in a far corner of the cave.

"My axe shall taste troll flesh this day," grunted Gimbal, making a two-handed sideways sweep that sliced the supposed troll in twain. He was instantly covered in sticky green ichor that sprayed briefly from the monster's torso but great was his astonishment when the wound closed and the monster was whole again. For the first time, Gimbal felt fear.


The players decide that their characters know what a troll is, but this isn't an ordinary troll. It's a gelatinous troll ...

If you let some players decide, they grab a MM and start reading the specs saying "But my character knows all this from being a librarian", ruining it for all other players...

Almost all players know what to do with trolls, but unless they are common to the area the character is from, lore about them isn't readily known IMHO.

Naturally, players will discover soon enough how to really damage them and after the first hit start to ask what can be done about the regen...
BUT: The next time they encounter a troll, they know immediately what to do!
