There's a list of "Difficulty Class Examples" in the 3.5 DMG on p31. That might be what you recall. It's a long list but it covers the whole range of Skills.
Yes, I realize that. I just wanted some kind of examples to show the GM as ballpark figures for how to set the DC of various perception checks.
In a recent game session, there was no check allowed for the PCs to notice an invisible creature in the room (although a check was made to allow an opponent NPC to notice a scry sensor). So my goal is twofold: to promote comparable checks for both groups, and to provide some guidelines on the types of things that might trigger a reactive Perception check and what the DC might be like.
Being able to show that with a roll of 20 my character can detect "a group of goblins moving across hard rock two weeks ago" would go a long ways towards showing that my character should at least have the chance of detecting an invisible someone.
In PF there is a flat DC 20 to notice that there is an invisible creature within 30 feet. (that doesnt tell you where, just that there is) the GM screen lists a few too.
HERE under the special ability Invisibility.The rulebook says that Invisible creatures get +20 on their Sneak roll.
Where is the rule that a flat DC 20 to know something nearby is invisible?
SRD said:A creature can generally notice the presence of an active invisible creature within 30 feet with a DC 20 Perception check. The observer gains a hunch that “something’s there” but can’t see it or target it accurately with an attack.
Good advice, in general.I advise being nice about this topic with the DM.
I agree. I have a rule that if I think the GM may have misruled something, I point it out, and will explain if I'm asked, but I drop it until after the game.After a game its fine to nicely point out a mistake so the DM can become better. As seen in this very thread not everyone knows about these rules.![]()
I wasn't following the tracks, I was just pointing out that I had found them.That would be Survival skill for tracking, not Perception![]()
d0pfsrd.org said:To find tracks or to follow them for 1 mile requires a successful Survival check. You must make another Survival check every time the tracks become difficult to follow. If you are not trained in this skill, you can make untrained checks to find tracks, but you can follow them only if the DC for the task is 10 or lower. Alternatively, you can use the Perception skill to find a footprint or similar sign of a creature’s passage using the same DCs, but you can’t use Perception to follow tracks, even if someone else has already found them.
