| #3 | Crafting crops | $1,500 | $3,719/hr | 0.4h | Keep for resource chains instead of raw export |
| #4 | Merchant bundle crops | $3,200 | $6,907/hr | 0.5h | Trade when merchant reward beats export cash |
Worker Assignment Priority
| Priority | Job | Stage | Best For | Warning |
|---|---|---|---|---|
| #1 · 1361 | Exporter | Scale | Turning stockpiles into upgrade cash | Consumes materials you may need |
| #2 · 1056 | Resource Collector | Mid | Wood, stone, and craft chains | Do not assign if storage is full |
| #3 · 903 | Fishing Worker | Trade | Fish trades and merchant offers | Weaker for raw early cash |
