Character Vision rules.


Rules Questions

Dark Archive

Ok I have went over the Vision and Light Rules which are good but they do't answer my question of: what are the distances under normal light conditions ( bright sunny day, outside , clear skies and flat terrain) can a character see? is there a rule or should I use what little common sense I posses?


As I mentioned in passing in another thread, I think the question ought to be what object of a given size can a character see at a given distance, because you can generally spot a tree from a much greater distance than you could spot a dog in the same conditions.

Yeah, there are size modifiers for stealth, but those don't mesh well with the penaties for range, IMHO.

Well i guess the Perception skill gives a little bit more clarification but it seems a little ridiculous. Notice a visible creature:DC 0 +1 per 10ft of distance.


I just ran across this note on another message board:

"According to the 2e Players Handbook, under clear sky in daylight, the maximum range at which a man-sized object can be seen is about 1500 yards, if its moving. If it isn't, this drops to 1000 yards. At 500 yards, you can roughly identify the thing- shape, color, creature type, etc. At 100 yards, you can make out an individual's identity ("Hey, that's Bob!")."

Now, I have no idea how accurately the 2e PHB modeled this, but this is the kind of thing I'd like to use as a starting point, applying modifiers as needed for differences in size and distance, plus light conditions, movement, other objects blocking line of sight, etc.

The current Perception rules as I understand them would give you at best a DC 82 to spot a Stone Giant at a distance of 300 yards across an open plain in broad daylight:

DC 0 to spot a living creature
+1/10' (300 yds = 900 ft = +90)
-8 Stealth penalty for a Huge creature
-2 favorable conditions (open plain in broad daylight)


The way I would understand seeing something like a person, the +1 DC every 10 ft is noticing detail. I mean even at the end of a football field (300 ft), most people are going to notice a person, someone who even doesn’t have 20/20 vision. It’s the detail you won’t notice. What color is their skin? What color are their clothes? Do they have a hat on? Or the really good perception checks…Are they wearing a ring? Are their shoes tied? Or, is it someone you recognize?

So for just noticing the person from a distance, I would keep it at 0. Unless they are just insanely far, and then you could adjust accordingly by DM’s prerogative. But finding it harder to notice someone at a hundred feet compared to 10 ft? I can’t agree with that. You are going to notice them at both distances, you just won’t notice as much detail at 100 ft.


Personally, I think that +1 should be 10 ft per size chategory of an object (10 for fine, 20 for diminutive). A medium creature would be a large object, and I would give it a +1/50 ft. A house would be gargantuan or collosal, so +1/80 or 90 ft.

Combine this with the size bonuses/penalties and you get some interesting results. This is for a person with no bonus taking 10:
House: -16 stealth, take 10 for 26, see out to .44 miles. If you have a +3, its half a mile.
Person: 10, see out to 500 ft (about 1 block)
halfling: 6, see out to 240 ft. (half a block)
Tiny (a book): 2, see out to 60 feet (other side of your house)
smaller than tiny you never automatically succeed.

Now, I haven't used this system at all. I just came up with it, but I'm liking it the more I think about it.

1 per 10 feet, +/- size bonus,

give buildings -5 (from effective dex of 0)

so a huge sized barn, at 100yards (300 feet) is perception check 17...

yeah, thats dumb

a gargantuan barn would need a spot check of 13.

a colassal barn needs a check of 9.

without the extra -5 for buildings its even dumber (checks of 22, 18 and 14).

For the baseline, you can find the "Maximum Encounter Distance" indicated under the description of each terrain type. This is the maximum range for a Perception check to detect a creature in that terrain.
