Prepare for the journey
Check off what you have ready before entering, crafting or changing your build.
Step by step
- 01
Read the item's current level and options. Separate item-level upgrades from additional options, creation recipes and elemental combinations.
- 02
Choose the jewel used by that route. Bless, Soul and Life have different jobs; they are not interchangeable extra upgrade chances.
- 03
If a recipe asks for a bundle, confirm its size and level. A bundle of ten and a bundle of thirty are distinct ingredients.
- 04
Open the correct combination and check that the intended output is shown before confirming.
What makes the difference
Keep recipe jewels separate from the set you intend to spend on experiments. A future wing craft can be delayed by using all its materials on incidental upgrades.
