Early Upgrade Priority
| Tier | Target | Why |
|---|---|---|
| S | First bottleneck fix | Buy the rod or knife upgrade that removes the slowest step right now. |
| A | Second core-tool upgrade | Balance the opposite side so extra catches can actually become cash. |
| A | newgame cash spend | Use free cash to shorten the route, not to gamble on a random luxury. |
| B | Starter bait / bobber | Good only after scaling speed can handle the additional fish. |
| C | Collection-first spending | Useful later, but weak before the money route is stable. |

Tier list FAQ
The best purchase changes with your bottleneck. An A-tier rod can be the wrong buy if your knife is still slow. A B-tier bait upgrade can become strong after your rod and knife are balanced. Read the list through your current loop, then test the result with one short session.
