Assuming you have successfully Hidden, can you:
- Continue to be not 'clearly visible' while moving and remain Hidden?
- Become 'clearly visible' while moving and remain Hidden?
In the description of the Stealth skill, it says:
Make a Dexterity (Stealth) check when you attempt to conceal yourself from enemies, slink past guards, slip away without being noticed, or sneak up on someone without being seen or heard.
So you can definitely move unseen with a Stealth action, but is that allowed in the Hide action?
The sidebar on "Hiding" states:
Until you are discovered or you stop hiding, that check's total is contested by the Wisdom (Perception) check of any creature that actively searches for signs of your presence.
You can't hide from a creature that can see you clearly, and you give away your position if you make noise, such as shouting a warning or knocking over a vase.
Passive Perception. When you hide, there's a chance someone will notice you even if they aren't searching. To determine whether such a creature notices you, the DM compares your Dexterity (Stealth) check with that creature's passive Wisdom (Perception) score, [...]
The rules clearly state that in order to hide you only need to be 'not clearly seen' and it is successful if you beat the opponent's Passive Perception. Your position is given away if you make noise (although you are not revealed). If an opponent takes the Search action to make a Perception check and beats your Stealth roll then you are discovered.
So the Hide action is a Stealth roll contested by Passive Perception. Creatures can contest the roll with the Search action using their Perception. Unless a creature opts to no longer be hidden, this is the only ways they can be revealed?
This seems to indicate that moving has no bearing on remaining hidden.
