So last year I've completed dark realm and whole Darkrai quest. The point is I didn't get the clone, because I didn't even know it was available unless some conditions are met.
Reading this post, I thought, that I may be able to return to dark realm, to get my clone pokemon this time but after beating Horon, I just received the mount.
Is there any way I can go back to dark realm or not?

I dont know if youre still able to get a clone this year but from what I know Horon has a 3 day cooldown. So if Alucard hasnt already respawned on his castle on the third floor you might want to try to challenge him again in 3 days.

Bump.

So basically if I haven't got marowak during dark realm I won't be able to beat hardmode Umbra aswell? 🙂 That's just great. Really thougtfull.

You can go back to Dark Realm and "recruit" the Marowak for the Battlefield quest. @Xytreh

The point is how I do that 🙂

You have to beat Horon boss in the Dark Valley, north of Necropolis. Make sure to not let one of your pokemon faint.

That should respawn Alucard in his castle on 3F. Beat him with a pokemon, which has the move Miracle Eye. Then youre able to go back to Dark Realm.

Thanks. It's a little bit dumb that I can't read about it anywhere. I've already beat that boss and didn't even know to check alucard... And with miracle eye. Damn 😉
