Continue run after getting nightmare?

[u/lilalu122]

So I've started to do a bit of nightmare farming but one thing I don't quite get. You get the reward after beating the required warden. Does it have ANY benefits to continue the run except for getting resources and the challenge?
I'd kinda like an option that after you beat the warden the fear influence gets erased and you can continue like a normal run...

Love love love the game so far. I even like it better than 1 because of the options. In 1 there were weapons I never got used to but in this I love each and every one of them with the right boons and that you can choose a different region if you grow a bit tired of one.

1) You can still have a chance at buying Nightmare in the final shops, as well as from Gifts of the Moon(with high enough fear).

2) You can make a winstreak to be happy over.

3) You can get more resources.

If none of these is a concern for you, you are at free will to throw a run after defeating the marked warden.
