Harder Items Mod[Discontinued]
Warning: This mod is no longer in development.
The original vision was to add a second layer to the base game that would make obtaining every item require double the effort—either through more complex crafting or labor-intensive actions. However, plans have shifted, and I'm now focused on other project goals. While the mod idea was solid, given the range of similar mods already out there, I don't think it offers much new value.
Harder items, at the moment, doesn't contain a ton of content, but it will suit players aiming to dial up the survival challenge. The main concept here is introducing resources and items that closely mimic vanilla items—but at a much higher resource cost.
Available Content
Right now, there's just one new item: Nova Star. Think of it as an intermediate crafting component used in the global Nether Star production line. For the moment, the Wither actually drops Nether Stars directly (same as vanilla), but that's all about to change.
Upcoming Enhancements
The next update will reconfigure the Wither boss mechanics: instead of dropping Nether Stars, it will start dropping Nova Stars, forcing players into an extended crafting chain. Working out these boss-spawn mechanics has been a bit tricky tech-wise, but progress is steady.
Expansion is ongoing with plans to add new resources, consumables, and tools crafted using more time-consuming recipes. You may well need more mod integration down the line, but for now, changes are rooted in vanilla mechanics.
