So, what level is recommended for this? I was told to do it but I can't even beat the first battle... They are the exact same level as me but it's hopeless. I have no quests left and neither of the areas have quests on the board.

What do I do?

The nightfall dungeon is meant for level 30 I think. But the boss battles can be very difficult, so unless you have a strong team with very good equipment, you might want to be a few levels higher before attempting the dungeon.

For now, I'll suggest you move on with the storyline. You should have the 3rd region, astryl's vale, available now. The 3rd region only allows you to be in one zone at a time, and the festival zone is part of that region. So if you're in the festival zone, you'll have to exit in order to access the other zones.

Only the 3rd region have "tasks" that you can do more than once. The first 2 regions only have one time quests that are part of the storyline.

I don't have the 3rd zone... And absolutely no quests in my quest log. I searched everywhere but to no avail.

Sorry, was tired and my mind translated wrongly. You should be at the 2nd region now, Umbra forest.

You will need the 3rd party slot, buyable from the sanctuary in order to clear the dungeon.

There won't be any quests available from the 1st region anymore.

I do have the 3rd slot open and I do have Umbra. :) And hey its ok! I totally understand that. Being sleepy makes your mind go all mushy. xP And yea, I might try that. You mean I need to clean the dungeon thing in
the Umbra Forest?

What I meant is that Umbra forest is the continuation of the storyline, so that's where you should explore for now. Until you're a few levels higher, and more prepared to try the nightfall dungeon

Okay, gotcha. :)
