Having given exhaustive consideration to RAW, CSRs, designer remarks, and the FAQ, here's what I'm moving toward for Stealth. I claim that save for one ruling, these are RAI, not house rules. Your feedback is really appreciated.
I think at least two of these points are house rules, but I applaud that more people are acquiescing to the 4th edition paradigm of stealth rather than holding on to the 3rd edition version.
1. If you have cover, concealment, or a diversion from any source against all your enemies in your turn, you can use stealth provided your DM deems the given situation appropriate. Allies usually aren't appropriate cover for stealth; they don't provide cover in your turn, or not from all your enemies. Carrying a light source prevents you from hiding.
I think VK makes too much of the proforma rule of DM approval of appropriate use of skills.
I am undecided of whether ally-provided cover is appropriate for stealth. There is some sense to a ranged attacker poking out from behind an ally. This is easily defeated by the perceiver merely moving for a different line of sight, removing the cover and ending the stealth. I look forward to September errata, and wouldn't argue with whatever the DM at the table ruled.
This is definitely a house rule.2. You hide using a minor action, or a power or skill other than stealth that explicitly grants a check.
Looking at 188:
You do need an action during a "stealthable" condition (ie, distraction, cover, concealment) to stealth, and it needs to be an action that doesn't contradict stealth (like attacking). For that stealth to last beyond that mere action, you need to end the action in a "stealth able" condition.
I think that is a better summary of 188 than the invented 'minor action'.
So a move into concealment, or a move into cover, could be used for a stealth check. A move out of concealment with a distraction and then ending in concealment could be used to stealth. I think a minor action for stealth in those situations would be redundant.
3. Roll your stealth check against the highest passive Perception amongst your enemies. You must roll equal or higher than that to get a success. Your enemies don't do anything or roll any dice.
4. You are not hidden from any enemy if you don't roll a success. You are hidden from every enemy if you roll a success.
With the caveat that only intelligent or team work enemies would obviously share information as a free action, I agree.
Because enemies can freely share information is a free action as RAW, I think this does meat the test of RAW. From Mearls' post, I think it is also RAI.
It is also a lot easier for the DM to keep track of one target number.
5. Being hidden means that enemies who are not alert to your presence don't become alert to you, you have combat advantage, and you have displacement (on yourself only) against ranged and melee attacks.
Using Displacement instead of the Targeting What You Can't See rules is a direct contradiction of the new FAQ and bizarre to me.
I really believe you should note that as a house rule. Good for you if you like it.
6. Enemies who are alert to you can attack and try to spot you. They can make active Perception checks in their turns using minor actions. You are no longer hidden if any enemy rolls equal or higher than your stealth check, or hits you with a ranged or melee attack.
7. Enemies who aren't alert to you can't attack or try to spot you. They become alert to you anytime you stop hiding in sight of one of them.
8. Your hidden condition ends as an immediate reaction if you attack, shout, take an immediate or opportunity attack action, or choose to stop hiding.
9. Your hidden condition ends as an immediate interrupt when you lose cover or concealment from one or more of your enemies or create a light source, unless you were taking one of the actions listed above.
10. You are never hidden from your allies.
Relevant modifiers to keep in mind are penalties to Perception due to interposing lightly obscured squares (-5), penalties on attacks due to cover (-2), and penalties on ranged or melee attacks due to concealment (-2, stacks with cover).
These I agree with.
