The rules on PHB25 only talk about check results, not rolls. It only indicates you are comparing one result to another, not one roll to another.
See also 178 under the heading Opposed Checks. I feel that is unambiguous. Stealth is even used as the example. Both parties roll. Well, it says characters, but surely no one would be churlish enough to make a meal of that, would they?
Furthermore, PH179 states that you make a passive check if you are not actively using the skill. My interpretation of this is that you make a passive check whenever it is not your action. I also interpret this to mean that if it is your action, you always make an active check.
My own reading of the example on PHB179 is that it describes a 'ready' state of watchfulness. It reads
'you aren't actually looking for danger'. Were you in an 'alert' state of watchfulness, you would make active checks.
Related to that, I've been scouring RAW for somewhere that tells you opposing checks take an action. So far as I can find, there is no such wording; have you found any? I can find examples of the opposite, e.g. Bluff is opposed by Insight, and it sure seems like the Insight user gets their opposing check with no action.
So, if I am hiding from you on my turn, I make an active Stealth check against your passive Perception check. If you are trying to spot me on your turn, you make an active Perception check against my passive Stealth check.
The RAW doesn't say this for Stealth, it only appears under TWYCS
'when a creature is invisible, you're blinded, or fighting in darkness you can't see through'. The Stealth rules block unambiguously instructs you to make an opposed check, and those are active.
I understand where you are trying to go with this. Make stealth apply only to the current action fixes a bunch of problems, especially when for stealth during free actions.
It sure does. Even if you don't spam them, a free check in each opponent's turn to get (re)hidden feels problematical. Stealthy free actions though, well you can ignore those. They're like a tree falling in an empty forest.
Unfortunately, I think this interpretation fails the common-sense test in a big way. It means you are hidden while you are moving, but as soon as you stop moving, you are no longer hidden. Later shouting and attacking revealing you doesn't matter, because you are revealed anyway when your action is over.
If a Rogue uses Riposte Strike and then attempts to move stealthily, the situation can arise where an an attack reveals them during their stealthy move. Other immediate interrupts can have the same effect. Also it is important to know that an attack performed stealthily doesn't need a Perception check to notice. Same goes for shouting. Without that wording, you might try to shout
unheard.
It means that you are never hidden unless you are currently acting. TWYCS can never apply to being hidden, because you are never hidden when you enemy is attacking.
I'm glad you spotted that. I found it a rather nice outcome. Incidentally, compare the wording under the Superior Cover or Total Concealment caption of the Stealth rules block with the TWYCS rules. They're very similar. It's just a feeling, but I find the inclusion of that wording separately under Stealth suggestive that RAW never intended to hook up Stealth to TWYCS. That and the absence of wording instructing us to connect them, which is kind of an incredible omission, if accidental (FAQ notwithstanding).
I think you would get a more reasonable result if you just assume that hidden is a lasting condition, but you cannot be hide as part of a Free Actions (otherwise you get infinite Stealth checks). That hidden is lasting is strongly implied by the RAW. To disallow hiding with a free action, I admit you would have to appeal to RAI.
Absolutely. At the point you did that you no longer have guidance from RAW as to which actions should be permitted and which shouldn't. My earlier position, feet squarely in the
lasting condition camp, was to call for a separate (minor) action to get hidden with (or use a power or skill other than stealth that explicitly gives you a check). That is a solid ruling, if you want stealth as a lasting condition.
My firm belief is that letting actions be performed stealthily
and at the same time letting stealth be a lasting condition is a source of problems, confusion, dystopic balancing issues, and makes the mechanics extremely tough to resolve. Pick one way, make that way work. I'm writing an open letter to WotC on this subject on their forums.
BTW, I am really enjoying your analysis of this problem. Your posts on Stealth have gone a long way to refining my own interpretation of the rules, even when I disagree with you.
Thank you! It makes an encouraging difference to hear something positive.
