In the new errata, the stealth rules get the following update:
- Hide [Action] (p. 368) In the second paragraph, “you have the Invisible condition” is now “you have the Invisible condition while hidden”. In the third paragraph, “The condition ends on you” is now “You stop being hidden”.
I think this cleans up some of the wonkiness around using Invisible for hidden creatures, but also introduces hidden as a pseudo-condition. There still might be some tension within the rules. Can a creature that has the ability to see invisible automatically find you?
Reading the rules, I think the answer is yes. The Hide action specifies that you stop being hidden if an enemy finds you. However, if you still fulfilled the conditions for attempting to hide, my sense is that you should remain hidden.
Is that take crazy or am I on to something? I think the new errata is pretty elegant, but it doesn't quite go far enough. On the other hand, I imagine we'll see the rules evolve over time.
