Spotting caltrops?


Rules Questions


What is the DC for a Perception check to notice caltrops?

*Is* there a Perception check allowed?

I've never sprung caltrops on PCs before - always thought of them as a tool for PCs to use against monsters, I guess. So I never rolled Perception checks for the NPCs to spot them; just did the attack rolls.

I think PCs would be annoyed if they didn't get the chance to even determine if there were caltrops in a given square, though. But I can't find any suggested DC in the caltrops section or the Perception section of the CRB.

Is there any DC out there that I just missed? If I had to guess, I might go with something like a DC 15 as the baseline, then adjust it from there with favorable/unfavorable modifiers. Caltrops must be pretty big in order to do what they do, but still it wouldn't be an automatic thing to spot.

House ruley as all hell, but you're right, there are no actual rules that cover this, but I would borrow from the Survival skill, as follows:

Perception : notice a visible creature: 0

Survival: Size of creature, fine : +8

Survival: Number of creatures (approximating 25 caltrops to a 2lb bag): -8

Modify by range and conditions, as per normal Perception rules.
