Is there an unspoken list of places you shouldn't miss when leveling up?

[Innocenza]

Hi!

I'm wondering if there is an unspoken list of places you should visit before getting locked out, or for some other reason can't visit, while leveling up?

Thank you.

Yes.

The starter area Arete is locked forever once you leave it, which is why its important to do all quests there to get stuff like the free ground vehicle, the poison damage bracer or the scope. Have a look at this guide on Ao-universe.

The next dungeon is the subway, which can only be entered while being level 25 or lower (although one can still level up a bit higher once inside). Check out this link to the subway at Ao-universe.

Afterwards comes the temple of three winds with the level lock of 60, then the Biomare research facility with a max level of 100.

Thank you.

I have a follow up questions after looking at the guides of Temple of the Three Winds and Biomare - Foreman.

If I'm unable to loot the items I want after trying and then continue to level... will this hurt my character forever?

[Matammyr]

Nothing forever, no. Though a couple of items from Biomare are kinda nice to have even at 200.

I'm not sure you could get TIM scope somewhere else than in Biomare. But you can wear a different scope, if you miss that one.
Also Biomare recall beacon is nice for fast travel.
I can think only of these two items I would miss if outleveled Biomare.

Edit: collar is also sometimes needed (even at lvl 200)
