As far as I'm concerned, I suggest you read my posts 898, 905, 909 (at least,that's their numbering for me).
I have, but, as I noted, subsequent and concurrent conversations made it difficult to follow your exact position.
In the circumstance you describe I don't think that Tom can hide because Chick can see where he goes and hence keep track of him.
I translate that as:
1) no, Tom cannot attempt to hide behind Bob
2) n/a
3) because Chick can still see Tom, so his attempt to hide automatically fails.
Yes?
If Tom's player want to make a DEX check to see how still and quite Tom can be behind Bob, I've got not problem with that. But it won't make any difference to Chick's ability to see Tom.
Followup -- if a new observer, say Chick's companion Christy, enters the room such that Bob is between her and Tom, and Tom has indeed attempted to be still and quiet, would you compare Tom's ability check to Christy's passive perception and, if successful, allow Tom to be hidden from Christy?
(If someone - eg Bob - distracted Chick, it would be a different matter. The adequacy of distraction is a matter for GM adjudication, though presumably a CHA check would be one way to do it, or throwing a flash powder grenade, or something similar.)
Interesting. What effects would this have on an encounter that did not feature a halfling attempting to hide behind a larger creature? IE, what would be the benefit for attempting such a distraction in other situations? I'm curious because this seems as if it's a new mechanical requirement to enable halfling hiding opportunities. If, however, you routinely feature such distractions that allow other benefits to non-hiding lightfoots, then it wouldn't be so. Can you provide examples from your game as to how players have utilized flashbombs or CHA checks in encounters to distract opponents, and what they gained from doing so?
I am guessing that [MENTION=6787503]Hriston[/MENTION]'s view is similar to what I've outlined.
Thanks, but I'm sure Hriston can answer for themselves if they wish. Until then, I'd like to keep discussions with you on what you think and not what you think Hriston thinks.
What causes me confusion is that others are confused by the view. (Which is separate from whether or not they share it.) The conception of the fiction strikes me as very straightforward - if a halfling or an elf is actually being seen by someone, stepping behind a person or behind a rain drop won't change that, because those things don't block vision and the viewer can track the halfling or elf's movement.
I'm not confused that you can hold this view, I was asking for clarity because the discussion has spiralled into increasingly obscure and ridiculous semantic arguments over choices of word substitutions and definitional hijinks that clouded the basics. As I understand it, you would not allow anyone to attempt to hide in any situation where vision is not blocked. I infer (and correct me if I'm wrong) that this would mean that anything less than full cover or total obscurement would qualify as blocked vision.
However, if a halfling or elf is not actually being seen then s/he can vanish behind a person or a raindrop and then when s/he comes into someone's field of vision will not be noticed unless s/he isn't still or quite enough, which will occur (i) if the potential observer succeeds in a WIS vs DEX check, or (ii) the halfling or elf performs the sort of movement, or makes the sort of noise, that automatically makes him/her noticable (the canonical instances of this are attacking and shouting).
The only issue I have with your view is that it's not any different from normal. This is the general rule. The case you've carved out is that the Wild Elf and Lightfoot Halfling racial abilities only offer areas where being already hidden continues to allow you to remain hidden. However, the normal rules could also offer this, as hiding is something that can only be done if un-observered, but remaining hidden is more open to interpretation and seems to imply that one can sneak around in light obscurement or less than full cover. Essentially, your ruling means that no one can remain hidden in light obscurement or less than full cover unless they have a special carve out. The issue I have with that is that it handicaps stealth to situations where it's only useful to hide your presence when no one can see you at all -- ie, hiding only masks sound/smell/other because it never masks sight unless you have a special call out. That's the logical outcome I see from your argument when applied broadly.
