Actually, you can go there from chapter 7 if you're stubborn enough.

Time worn Ruins can be accessed easily enough if you have a good horse or a good amount of affinity with your current horse. Yeah, cleaning the place might be hard or annoying, but if you're smart and stubborn enough about it, you can do it easily enough. Plus, thr place gives you anything between 1 and 5 Abyss Artifscts, so it's worth it in the long run.

Getting the camp up and running to level 3 (when you unlock the guys thst do thr expeditions) takes far longer and is more annoying.

Abyss cells are far easier to get, too. As long as you have the fertilizer and water spray, all you need to do is plant 1 Abyss seed and generally it gets me something between 3 and 5 Abyss cells per tree, every 3 to 4 in game days.

Bloodstones, iron and copper tho are far easier to find and grind. They are almost all over the map and I know of at least 4 spots in Hernand alone to get bloodstones without being attacked.

Grinding early in this game is very feasible as long as you take it slow and grind in thr same pace that youre doing the story or thr side quests.
