Looking for some cool mods for a specific concept - can you recommend me some?

[Ellilea]

So I was thinking I'd like to play a playthrough based on a rather simple concept:

Indestructible walls + a very dangerous world outside

It's less about making a turbo difficult playthrough all over where you need to be on edge 24/7, and more about slowly expanding into a dangerous world, exciting excursions for resources etc, with a safe haven base to rest and regroup.

Sadly, it looks like there is no "Wrath of the Giants" for DST which would've been a cool first addition to the dangerous world (I found some Chinese mod for DST linked on WotG mod page, but it looks like those bosses might teleport? I don't know Chinese so I can only judge by gifs, YouTube didn't give me any useful results for it either. Do you know of any mods beefing up the giants? At least Bearger seems easier than DS version (I recall it was nerfed to prevent griefing, I'd like to undo that too if possible).

Also, any other mods you think would fit this idea would be great

Also a question - if your base is larger than 1 screen, do enemies spawn inside the walls, just out of sight? That would kind of defeat the purpose here I guess :P Thanks.
