Saltfire Day 64 2 September 2026
Swan
How do you make Swan in 8 merges?
- 1 Dew + Salt Brine
- 2 Brine + Ember Broth
- 3 Breath + Salt Dust
- 4 Brine + Dust Chalk
- 5 Brine + Chalk Shell
- 6 Broth + Shell Egg
- 7 Breath + Egg Bird
- 8 Bird + Brine Swan
Why is 8 merges the shortest possible?
Day 64 asked for Swan — a tier-4 element, one of the complex — and it goes in eight 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.
Two of the eight merges come straight out of the primordials — Brine and Dust — and everything else is built on top of those. The last step is Bird + Brine, which is where Swan finally condenses.
Now look at Brine: made once, then wanted in four different merges. That is the whole reason the floor is eight and not eleven. A step buys you an element for the rest of the run, so par counts distinct pairs, not branches of a tree — the second time the chain reaches for Brine it is already sitting in the tray, free. Counted as a tree, with a fresh derivation for every single ingredient, this same solution reads as eleven merges.
Swan has three 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.
