Grades and guaranteed fuses
Synthesis combines lower-grade gear and materials into a higher grade. For the lower grades, that's a clean upgrade — feed in the recipe and you always get the result. This is where you should fuse freely: there's no risk, so convert spare low-grade gear up the ladder whenever you have the materials.
Where it starts to bite: Immortal and up
The free ride ends at Immortal — the first grade where a fuse can fail. From there up, each attempt rolls against a success rate, and a failure consumes the materials without handing you the higher grade. This is the single most expensive misunderstanding in the game: players treat an Immortal fuse like the guaranteed ones below it and watch a stack vanish.
- Never attempt an Immortal-or-higher fuse on your last set of materials — assume it might take several tries.
- Check the success rate for the exact step on the synthesis planner before committing.
- Stockpile the materials for an expected number of attempts, not one — the planner converts the odds into a realistic material budget.
Planning the material cost
Because every grade is built from several of the grade below it, and the failure chance multiplies attempts at the top, the true cost of a high-grade item compounds fast. Rather than guess, the synthesis planner reads the in-game recipes and success weights and tells you how many base materials a target grade actually takes — and the farming guide shows where to stock them.

Frequently asked questions
- How does synthesis work in Task Bar Hero?
- Synthesis fuses lower-grade gear and materials into a higher grade. Each step has its own recipe and success chance. Below a certain grade the fuse always succeeds; from a threshold grade upward it can fail and consume your materials.
- Which grade is the first that can fail a fuse?
- Immortal is the first grade where synthesis can fail. Everything up to it is a guaranteed upgrade; at Immortal and above you're rolling against a success rate, so plan spare materials before you attempt those steps.
- What happens when a fuse fails?
- A failed high-grade fuse consumes the materials without giving you the higher-grade result. That's why the math matters — you budget for the average number of attempts a grade takes, not a single guaranteed success.
- How many materials do I need for a target grade?
- It compounds: every grade is built from several of the grade below, and the failure chance multiplies the materials needed at the top end. The synthesis planner does this math for you from the in-game recipe and weight data.
