Endgame content?

I beat twins-boss with 2 try.
And died in Cerim Sanctuary over 10 times, before drop this, need to serious upgrade armor and weapon. Need to find bear claws, silver ingots, where this seek - i don’t know.
It’s normal or what? I hope this is not important endgame content, and not a second main quiest target?

Cerim Crucible is around 25-30 lvl content. I failed most of the time until I was lvl 30 and beat the boss.
Benefit is you get more high end Items in the chests like silver, bear claws, etc. not only that but you get some of legendary boss weapons you might’ve missed out on (of course you have to beat the boss to get them)
I think it is slightly important, you do get a certain item for the girl at the end.

Okay, then what to do next 10 lvl? im 19 lvl right now.

At level 21 you should see a good power spike. I’d focus on challenges/bounties and farming the zones if the crucible is giving you a challenge right now.

After 21, you can continue to do the same or try your hand at the crucible again!

There is no other content in early game? Only this Cerim Crucible?

I’m afraid not, in comparison to other games this is Very Early access.
I think they just want to straighten out biggest problems first with early release.

Right now the “repeatable” content/end game is the crucible, which is not in its final form either.

I kept reading that the Crucible was full of chests. I ran it to the boss and there was a total of 3 chest and it was no better then the chests I can get in the overworld. So did they nerf the chests or are people exaggerating the benefits of the crucible, because Im not seeing it…
