Resonance is the increase of a character's Tier. Resonance can change the skills and increase the character's stats.
There are 4 tiers in total: N, R, SR, SSR. At tier SSR, the character can further resonate 10 more times to increase their stats, but their skills will not change.
This summary shows the number of materials required for the resonance of Ned as an example. This summary isn't accurate for every character. In order to know the proper resonance materials, please refer to individual character pages.
The region material needed for resonance depends on the character. A list of region materials, as well as the quantity needed for resonance, can be found below. For the region material specific to the character, check out the character page.
The character mineral specific to the character is also needed for resonance. Do note that SP characters do not share the same character mineral with their normal forms - their character mineral has a red illustration while that of the normal characters' are in blue.
From N to R: 4
From R to SR: 15
From SR to SSR: 30
Exceed & Convert: 10
When a character reaches tier SSR, the option to Exceed said character will be available.
Each time an exceed is performed, the character's exceed tier will go up by one level, denoted by a + (plus) symbol and a number next to the character's name. A character can be exceeded up to +10.
With every exceed, 50 Attack and 300 Health are directly added to the unit's base stats, capping at an effective +500 Attack and +3000 Health when the character's been fully exceed to their maximum potential.
Exceeding consumes Character Minerals, Advanced Region Materials, Resonance Soul Energy, and Curren.
Convert option is available when a character has reached +10 Exceed. It serves as the only reliable method to craft Origin Stone for Contract Crafting.
To perform Contract Crafting, players need to accumulate a specific number of Origin Stones required, which can then be used to craft any of the available characters in Contract Crafting.
This is done by converting 10 Character Minerals, 2 Tear of Dragon Slayers, and 2000 Curren into 1 Origin Stone.
