Saltfire Day 57 26 August 2026
Rain
How do you make Rain in 5 merges?
- 1 Breath + Dew Mist
- 2 Breath + Breath Wind
- 3 Mist + Wind Cloud
- 4 Dew + Dew Pool
- 5 Cloud + Pool Rain
Why is 5 merges the shortest possible?
Day 57 asked for Rain — a tier-3 element, one of the made things — and it goes in five merges. Not fewer: par is worked out across the whole recipe tree before the puzzle ships, and then proved by replaying the chain above against the game's own rules, starting from nothing but Salt, Ember, Dew and Breath. If that replay had spent one step more or one step less, the build would have failed and this day would never have run.
Three of the five merges come straight out of the primordials — Mist, Wind and Pool — and everything else is built on top of those. The last step is Cloud + Pool, which is where Rain finally condenses.
No intermediate here is wanted twice: every element the chain makes is consumed by exactly one later merge, so par is simply how far Rain sits above the primordials. There is nothing shared to save a step on — five links of chain, five merges.
Rain has two recipes in the tree, so the route above is the cheapest way in rather than the only one. Another chain of the same length is quite possible; a longer one is far more likely. Two steps fuse an element with itself (Breath + Breath and Dew + Dew). Self-merges are legal moves and a few elements only come out that way — always worth a try when a run stalls. Salt and Ember never appear in the short way through — though nothing tells you that while you are playing, which is rather the point.
