about dlcs and bosses

[Woldren]

My plan was to buy the dlcs after finishing the main game. Is it a mistake? Maybe the new bosses are here and there during the path?

First thing you should know is that world is randomly generated each time you reroll it and there are more possibilities than can happen on one playthrough. For campaign it means different order of worlds that you visit, random stories on those worlds, random dungeons, events, world loot and so on. Each dlc adds new story for selected world with its own custom overworld map, events, secrets, new archetype, dungeons, weapons, accesories.
Should you own dlc parts of it may or may not happen during your campaign provided it was generated after purchase of that dlc. Game is designed to be played multiple times, each time providing different mix of availiable content.

You will also have a possibility to start adventure's with dlc story, first time each provide package with only new stuff from than dlc. However to unlock adventures you need to finish that world for first time in campaign.

There's no "correct" order to the DLCs in this game. All of the World Stories are more or less independent from each other but still connected by each world's overall themes.

If you play through the DLC story from one world it will not spoil the other world stories.

The DLCs for Remnant 2 aren't a traditional linear experience they're more like a bag of parts that the game's procedural level generation can draw from when creates a world for you.

As such, what world stories you get and which order you experience them is is completely random.
