Goblin Queen (She/Her/Hers)
Yeah, in my view the problem with the RAW of HiPS is not that you need cover or concealment to hide with it - I think the text is clear you don’t. The problem is that for 1 minute of work, you get a benefit that only lasts for as long as you remain perfectly still. The effect of this being that the feature is useless unless you know exactly where whoever you’re trying to hide from is going to be, a minute or more before they’re going to be there. I can count on zero hands the number of times I’ve seen that happen in a game of D&D.Explicit beats general. In general, you can't hide unless you're obscured but for this feature specifically, you can hide so long as you press yourself against a tall tree or wall and you are camoflauged.
There may be an argument about not getting the advantage from the attack, but you still get the surprise.
