Recent DND convert here, DMing my first PF2e adventure (Malevolence).
I am honestly not sure whether this is a design intent or rules lawyering. Sneak action says https://2e.aonprd.com/Actions.aspx?ID=63
At the end of your movement, the GM rolls your Stealth check in secret and compares the result to the Perception DC of each creature you were hidden from or undetected by at the start of your movement. [...] You don’t get to roll against a creature if, at the end of your movement, you neither are concealed from it nor have cover or greater cover against it. You automatically become observed by such a creature.
"Invisible" condition (https://2e.aonprd.com/Conditions.aspx?ID=26) does not count as a cover, neither it is the same as being "concealed" (https://2e.aonprd.com/Conditions.aspx?ID=4). Also,
If you become invisible while someone can already see you, you start out hidden to the observer (instead of undetected) until you successfully Sneak.
So... if a creature becomes invisible while in full view of the party, and then tries to Sneak 10 feet away to a place without cover from the party... does the Sneak fail by RAW?
Full sequence of conditions:
-creature is in view of the party and is observed
-creature becomes invisible, this makes him hidden
-creature tries to Sneak away, but ends its movement without cover and not concealed
-creature can't become observed (as being invisible explicitly prevents it), but it autofails Sneak and fails to become undetected.
Where's the flaw in logic?
