So, we are kind of relying on Larian to be fair as DM and set up encounters that are beatable in some way, but that is true with or with out the 5e rule. Especially in the case of homebrew special NPCs it is on the DM to make them tough, but not total bullshit.
Agree. I am not too worried about encounters being too difficult. There will be difficulty settings in the final game, which I can adjust as needed. 😊
