Saltfire Day 67 5 September 2026
Stem
How do you make Stem in 6 merges?
- 1 Dew + Salt Brine
- 2 Brine + Ember Broth
- 3 Breath + Salt Dust
- 4 Broth + Dust Seed
- 5 Dew + Seed Sprout
- 6 Breath + Sprout Stem
Why is 6 merges the shortest possible?
Day 67 asked for Stem — a tier-4 element, one of the complex — and it goes in six 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 six merges come straight out of the primordials — Brine and Dust — and everything else is built on top of those. The last step is Breath + Sprout, which is where Stem 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 Stem sits above the primordials. There is nothing shared to save a step on — six links of chain, six merges.
Stem 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.
