Every era recipe from 1 to 60, priced with your server's numbers. Open a level bracket to compare all the options in it and see which is genuinely cheapest per skill level. Prices stay in this browser.
A profile sets the skill-up system, the free skill cap, which expansions' recipes count, and the HQ rate. Everything below uses Phoenix's era assumptions.
Cost each is your ingredient prices plus one crystal. Per level estimates the gil to gain one full skill level using that recipe, from the era skill-up model in synthutils.cpp: 60% skill-up chance below skill 50, 25% above, gain size from the retail weight table, and only when the recipe sits above your skill. A 5% break allowance is included.
Cheapest marks the lowest cost per level in each bracket among recipes you can actually attempt there. Recipes needing a guild key item, a sub-craft, or unpriced materials are still listed, just flagged.
Output is the normal-quality result at its sell price. HQ results are upside this ignores, and they matter most on cheap low-level synths.
Icons are drawn rather than taken from a wiki, so the page stays self-contained. Item names link to their item pages for full source and recipe data.
