How many caches to open
A cache drops one item out of five at fixed chances, so you need more openings than reagents — and the count is set by the rarest one you need. The left number is the average, the right one covers nine cases out of ten. The other reagents pile up well past what you use: sell the surplus or spend it on another craft.
| Cache | Open | What you need from there |
|---|---|---|
 Aetheric Reagent Cache M | 172–214 | Aether Ash
— need 24, chance 24% Ghostlight Filament
— need 24, chance 24% Veil Resin
— need 36, chance 24% Void Salt

What one craft really takes
The recipe is broken down to raw materials: what an NPC sells at a fixed price, and what has to come out of caches.
Any price can be replaced with your own — the tree and the shopping list are recalculated from it. An empty field uses our price, which is shown as a hint. What you type is kept in this browser.
