Why this is the cheapest path to Signal
We rank every known recipe for Signal by total crafts from the four starting elements, not just by the final combination. The two direct ingredients — Radio and Wave — cost 7 and 1 crafts to build from scratch, which is why the whole chain above needs only 8 crafts. The alternatives in the table below are ranked the same way: their "approx. cost" is the pricier ingredient plus one, so you can see at a glance which route actually saves you crafts — and which ones quietly waste five.
Alternative combinations for Signal

|---|---|
| Message + Smoke | 8 crafts |
| Message + ☀️ Sun | 8 crafts |
| Smoke + Stop | 8 crafts |
| Post + Smoke | 8 crafts |
