In the Heart of the Woods. You find this quest on Kaer Trolde's noticeboard or by walking into the involved NPCs in Faerlund. That is all in
Skellige.
Recommended level... uh... 28? Could also be 24. I am not sure.
Level 15 or 16 is a
good time to do
Novigrad. Or even to move on further and onto
Skellige.
However, I very much feel with you about the urge to clean up the
?s before moving on. I have a similar kind of OCD.
The thing about the
?s is that you get barely any XP for them anyway. For bandit camps, you only get XP for killing them - that would be 4-5 XP now, if there are 4-5 lvl 9 bandits. For hidden treasures and guarded treasures, you get the XP for killing the monsters guarding them. Monster nests provide a few XP for destroying them, which is nice; and Abandoned Sites give 120 XP or so. That general lack of XP for
?s means that you can basically do them whenever you like. They won't really cause you to overlevel your quests. Their main purpose seems to be to keep the players busy, and to provide a source for valuable stuff to sell.
Then, there's to keep in mind that
Velen has some
?s with
highlevel monsters. There is one with a lvl 32 (or 34?) basilisk next to
Oxenfurt. There are a bunch of them with lvl 24-30 monsters in the south or in the periphery. Tackling lvl 32 monsters at lvl 15/16 is not such a splendid idea.
I would do some of these
?s in
Velen, until I felt bored, and then I would move on towards
Novigrad. And I'd always be wary that the
? ahead might be guarded by a lvl 28 gravehag who'd like to eat me raw at my current level - so, I'd always be ready to run away.
