Yeah 230 points was a dungeon, and btw, I got lucky on some things, and unlucky on others. High physical slaves are either farmed from scratch, or found on the early days. I simply grabbed the best one I came across and built it up. Still haven't continued after day 8 but I do get bored eventually after so much grinding and micromanaging.
The most valuable thing you can get from the guilds, is an upgrade from the workers that allows you to disassemble items to get some materials back. Since I run dungeons non-stop I end up hoarding a bunch of items, and if you press shift while hovering over an item you'll get to read the materials it's made of. I've been lucky enough to end up with some dragon bones by day 14 and even made a chestpiece for a knight.
But anyways, there's always workarounds for when things get super unlucky. You either get to the quest before day 28, or pay 3k and it's really not impossible. If it turns out to be troublesome, simply run easy quests all the way. Though I find that to be a bit of a gamble and have to end up saving 3k of money.
I had a save for last version where I was aiming to farm the 100k with dungeons, and I had gotten past day 50 with like 30k or something, and I'm sure I had enough materials to make above 50k if I emptied my bags. Totally doable, just a lot of farming for something that's not intended.
I also find that it gets way easier when you start splitting into 2 or 3 parties running dungeons with like 1 or 2 main slaves and the rest farming experience. To the point where I get bored of that lol.
I like the game, and the RPG side of it is quite engaging, but I also understand it's an early version, although with a lot of content and hours of entertainment.
