looking for a novel I read a couple of years back - Think it was Korean, but not sure plot: the MC wakes up and there are stairs in his bedroom leading to an unknown place. He enters every night, and begin fighting monsters, gains abilities, and meets other people. Later a lot of other stuff happens, but think that is the gist of it. the dungeon level changes every night, and it is a different world think it was passed back when I stopped reading but wanna pick it up if it is going again. Thanks if you can help
Spoiler: Death in the dungeon Extra info, as long as you don't die before finishing the level of the night then you are healed, but if you die in the dungeon, you become potato mind in real life...
Sounds like Dimensional Sovereign. It has been taken down from TL site and NU links r dead too, so you'll hv to google the title.
