Fusion skills are randomly created and upgraded with elemental catalyst and primal catalyst. They are bound to your totem and cannot be removed or replaced.

Best Fusion Skills per Element

There are almost always several valid choices, and moreover the choice depends on your exact team and opponents.

I provide the usual choices per element in the following pages:

Optimal Strategy

Here is how many catalysts to spend at a time to maximize your odds.
It may be beneficial to stop at rank 4 and use the bad luck protection for the last upgrade.

When you have no skill yet	Spend 10 catalysts to gain any random skill - accept the temporary result
When your skill is rank 1	Spend 100 catalysts at a time to reach ranks 3-5 (or 10 to reach rank 2)
When your skill is rank 2	Spend 100 catalysts at a time to reach ranks 4-5 (or 10 to reach rank 3)
When your skill is rank 3	Spend 100 catalysts at a time to reach rank 5 (or 10 to reach rank 4)
When your skill is rank 4	Spend 10 catalysts at a time

Average Cost to Reach Rank 5

Assuming you follow the optimal strategy described above. Hope you like casinos... :(

Rank 1 → 5	2023 catalysts (100 at a time)
Rank 2 → 5	2021 catalysts (100 at a time)
Rank 3 → 5	1999 catalysts (100 at a time)
Rank 4 → 5	1830 catalysts (10 at a time)

Average Cost to Reach Rank 4

Rank 1 → 4	749 catalysts (100 at a time)
Rank 2 → 4	745 catalysts (100 at a time)
Rank 3 → 4	617 catalysts (10 at a time)

Bad Luck Protection

Whenever you spend catalysts you gain crystallized might. Once you gain 3000 your next upgrade will automatically succeed by one rank. Better make sure you use that on a rank 4 skill!

To reach this bad luck protection, you need to spend either 3000 elemental catalysts or 7500 primal catalysts.
