Start with the official launch scope and use the version log before copying a Hard Mode route from an older build.
The official launch and 1.0.19 notes both describe additional Hard Mode content, rewards, and progression changes.
Exact modifiers and reward tables are being built as versioned records. Older advice should be checked against the current patch before reuse.
These answers stay version-aware instead of promising a timeless meta.
Sometimes, but the answer depends on which entity changed and whether the old interaction was fixed or rebalanced.
Open the relevant version page, compare the old and new values, then check the linked entity. The current update log marks most recorded 1.0 builds as usable with a targeted re-check for changed interactions.
The site will expand this into an affected-build index as more build records are added.
