My 3-in-1 Crystallized Tunnel Base (Chromite Farming, Raid Boss Preparation, & Mass Breeding)

139 points · submitted Jul 2026 by u/CamoKoopa182 · Farming Bases

This base has been in the works for a good while, as when I first made this base I was needing to brainstorm what to do with the upper floor. But now, I’ve decided to designate the top floor for mass breeding, to help build armies for Raid Bosses.

So with that done, I now have a 3-in-1 Cave Base designed for Chromite Farming, Raid Boss Preparation & Recovery, as well as Mass Breeding!

First of all, you are a mad genius. Secondly, it is clear I will never get to play this game right.

Nah, just do a dungeon with 4 star Smokie and the multicutter.... enough to last a long time. There are far better expeditions to run.

This is really great, hopefully this will still be buildable in 1.0 but I have Two questions please; is this base raid/visitable, and how did you measure for placement with still getting the chromite?

1) don't exactly know what you mean by "raid visitable," but I can tell you that I primarily use the designated "raid arena" when doing raid bosses instead of using the actual base for raids.

2) in the recent updates you can't place foundations close to the floor in the cave areas. So what I did what place a column at the start of the cave and built off of that. Working with the cave walls as I build. Since the floor isn't covered, it still allows chromite to spawn.

I’m curious if this base gets merchant visitors and random spawning raids like lovanders.

Thank you for the response, appreciate the insight on how to start a build like it.

Raids, at least in 1.0, will not happen if you surround the base with a wall or barrier like the gate seen in the video. I cant say with 100% certainty there wont be any raids there but i would be interested in testing myself. Great build, Op!

Oh that. Well, I don't know about merchants, haven't had one spawn there yet. But overworld raids? Most definitely! Tho the tight corridor leading to the cave should make them relatively easy to handle. Lol

I just have overworld raids turned off in my world.

jesussssss do you mean the room or the tunnel? ...i build there before for fun-sy ...nothing crazy with foundation(when you could) and testing stuff..and remembering the length of that tunnel is no joke!!! Did it take long? xD

Oh I meant the room. All things considered it really didn’t take me all that long to set up. Lol

Is this location still viable after 1.0?

Sadly no. The put an Ancient Ruins in this cave, and you can't build near it. 😭
