@Iry I can see how you can take the wording and say that it naturally implies the converse - that you can hide whenever a creature cannot see you clearly - but the halfway house of allowing a creature to stay hidden when they move from a heavily to lightly obscured area seems untenable for two reasons
- How do you justify excluding the implication that any creature can try to hide when it can't be clearly seen. The least thing you should believe - if reading it as you do - is simply that creatures should be able to hide whenever they cannot clearly seen.
- But if you do read it that way, how do you justify their presence of skulker and mask of the wild in the game? Just designer mistakes?
@Flamestrike and I exclude designer mistake (at least in this regard) and don't pick-and-choose among implications. So we feel our reading is the more consistent.
