In my campaign, I recently acquired Legendary Sneak, meaning I do not need cover nor concealment to retain my Hidden and Undetected conditions when using Stealth. This has some excellent benefits outlined in my other question on the matter.
But it does have a significant drawback. Neither Hide nor Sneak allow for you to 'not hide' from allies. This means that if my friendly cleric wants to use their 2-action Heal on me, they must succeed at a Seek action or DC 11 Flat check (assuming I've overcome their Perception DC with my most recent Hide action) among other things my allies may want to do to help me.
(Hide) ...compares the result to the Perception DC of each creature...
(Sneak) ...compares the result to the Perception DC of each creature you were hidden from or undetected by...
What options, if any, allow me to remain or become Observed by my allies but not all creatures that could perceive me?
