Species options are easier to compare when you begin with the rules context or source set you intend to use. This avoids mixing entries from unrelated revisions or campaigns.
Use filters as a shortlist tool
Filters should build a manageable shortlist, not make the decision for you. Once the list is small, read each full entry and compare features in context.
Practical check
Keep the process small and testable. Make one meaningful change at a time, confirm the result, and preserve enough context to undo it if needed.
Watch for version differences
Names, traits and formatting can change across rules revisions. If two entries look similar, use source and version information to confirm which one you are reading.
What to avoid
Avoid mixing advice from unrelated builds as if every copy behaves identically. Version, file structure, enabled data and hosting method can all change the correct next step.
Create a repeatable comparison
For a consistent decision process, compare the same fields for every option: movement, size, key traits, limitations, source and any campaign notes.
Summary checklist
- Work from a clear reference goal.
- Keep source and version context visible.
- Preserve a known-good local backup.
- Test paths and browser behavior before making broad changes.
