Okay. And? It also says lightly obscured can involve such areas as dim light, patchy fog, or moderate foliage. What am I missing? What argument were you trying to make? That the words "lightly obscured" don't mean what I think it means? Are you familiar with "obscured" at all? If something is "lightly obscured," you consider it to still be "seen clearly." I don't. The usage of those words have meaning to me. Where does that leave us?
I don't think obscured and seen clearly are intended to be in opposition. I mean, sure, seen absolutely clearly is completely unobscured, but I don't think that's the meaning that was intended when clearly was added, especially considering that the original text was thought to have captured the intended meaning well enough to have published it in the first place. How do we get from merely seen to seen with absolute clarity? No, mostly seen clearly can be somewhat obscured, but not enough to hide. Mostly obscured is not seen clearly enough to deny hiding, although you might be seen
un-clearly. Heavily obscured areas include things like dense woods and moonlit nights, areas where a certain degree of visual clarity is possible, so it isn't as if "blocks vision entirely" or even "imposes the blinded condition" have the kind of absolute meaning in the fiction which you seem to favor.
I'm sure you have a citing to corroborate your interpretation of *why* the Sage added "clearly". I look forward to reading his insights on the reasoning for that clarification.
From the most recent update (10/24/16) of the Player's Handbook Errata PDF:
Using Ability Scores
Hiding (p. 177). The text clarifies that the DM decides when circumstances are appropriate for hiding, and the first sentence of the second paragraph starts as follows: “You can’t hide from a creature that can see you clearly …”
This just basically reiterates what the actual text changes were. What this particular erratum tells us is that Crawford felt the need to state more obviously that it's the DM's duty, not the player's, to decide when it's even possible to make a DEX (Stealth) check to hide. The addition of 'clearly' throws a shade on the notion that this decision might be taken out of the DM's hands because a creature has line-of-sight to the one trying to hide, a concept which doesn't really appear in the PHB (not sure about the DMG) anyways. For example,
in the fiction you
can be seen on a moonlit night, but not clearly enough to prevent you from hiding.
Again, I'm not sure how you reconcile something that is "lightly obscured," by definition, with something being "seen clearly." I just keep getting hung up on the meanings of "obscured" (even lightly) and being seen "clearly." You say binary. Yet, the rules themselves have three degrees. Not two. "Seen clearly" (as I see it, or un-obscured if you will), "lightly obscured" and "heavily obscured". Binary? Not by definition, no.
I said whether or not you are seen clearly is binary. Either you are or you aren't. It sounds to me like your "seen clearly" is binary as well. You just put the line between completely un-obscured and lightly obscured, whereas I put it between lightly obscured and heavily obscured. The way I reconcile lightly obscured with seen clearly is that "seen clearly" doesn't have to mean "seen with absolute clarity". It can mean "seen clearly enough for the purpose of denying an attempt to hide".
That's a fine interpretation for your table. I concede that. You can enjoy the heck out of playing it that way. Pardon me if I disagree with your interpretation and choose to play it the way I read it.
Thanks. I feel the same way about how you choose to interpret the rules at your table. I'm actually interested in understanding how that plays out differently at your table, because I'm having some difficulty reconciling everyone being able to hide (with the DM asking for a check) when only lightly obscured (if I'm correct in understanding that as your position) and certain rules which imply that heavily obscured provides some added utility to the hider. For example, the invisible condition's statement that the invisible creature is heavily obscured for the purpose of hiding would seem meaningless if everyone could hide when only lightly obscured. Why would it say "heavily obscured" instead of just "obscured"? What added value for the purpose of hiding is there to being heavily obscured?
