Saltfire Day 76 14 September 2026
Slate
How do you make Slate in 7 merges?
- 1 Breath + Salt Dust
- 2 Dew + Dust Clay
- 3 Ember + Salt Ash
- 4 Salt + Salt Crystal
- 5 Ash + Crystal Stone
- 6 Stone + Stone Boulder
- 7 Boulder + Clay Slate
Why is 7 merges the shortest possible?
Day 76 asked for Slate — a tier-4 element, one of the complex — and it goes in seven 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 seven merges come straight out of the primordials — Dust, Ash and Crystal — and everything else is built on top of those. The last step is Boulder + Clay, which is where Slate 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 Slate sits above the primordials. There is nothing shared to save a step on — seven links of chain, seven merges.
Slate 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 (Salt + Salt and Stone + Stone). Self-merges are legal moves and a few elements only come out that way — always worth a try when a run stalls.
