Add-On Skills are a form of skills, separate from Class Skills, which can be generated from the Class Counter. They grant many beneficial effects upon generation. You can keep up to 3 Add-On Skill results per Class, and you can switch between results or sets of results at the Class Counter between activities.
Of note is that Add-On Skills are always active regardless of current Class combination. This means that for instance, Gunner's Add-Ons will be active even if neither your Main Class nor your Sub Class is Gunner.
All Add-Ons generate with 1 Main Effect and 2 out of 4 possible Sub Effects, with each effect having a level between 1 and 20. Generating an Add-On Skill for the first time for each Class will also grant you a permanent +1% Tri-Boost.
Add-On Skill Creation
Add-On Skills can be created at the Class Counter. Each creation attempt costs N-Class-Excube ×1 of the respective class, as well as N-Meseta. As you generate Add-On Skills, more creation options will become available, with later options costing more N-Meseta but raising the minimum level for all effects in the generated skill.
|Skill Creation Level||N-Meseta required||Minimum Level of Add-On Skills||Unlock requirements|
|1 Skill Creation||5000||1||Available from the start|
|2 Skill Creation||10000||5||Create Add-On Skills 5 times|
|3 Skill Creation||50000||10||Create Add-On Skills 20 times|
Once the Add-On Skill is generated, it must be saved on one of the 3 slots allowed per Class, or else the results will be discarded. You will only gain the permanent Tri-Boost effect for a Class if you have at least one Add-On Skill saved for that Class.
Note that the higher-level creation options do not give you a greater chance of getting higher-level effects. For each effect of the Add-On Skill, the game always picks a level between 1 and 20. After that, if the level chosen is below the minimum level you have selected, it is raised to that minimum level.
The following table presents the odds of generating levels of the Add-On Skill:
|Add-On Skill level||Odds of generation|
This means generating Add-On Skills via 2 Skill Creation has a 44% chance of staying at level 5, while Add-On Skills created via 3 Skill Creation have a 74% chance of remaining at level 10.
Add-On Skill types
Add-On Skills always generate 1 Main Effect and 2 of a possible 4 Sub Effects. Each Class has 1 unique Main Effect and 1 unique Sub Effect, with the remaining 3 Sub Effects being shared with other classes. Each Sub Effect has the class's name in parentheses, meaning that they are considered separate boost effects. If you generate the same Sub Effect for multiple Classes, they will stack.
The Main Effect is the primary effect generated from the Add-On Skill. Each Class has a fixed, unique Main Effect, which is guaranteed to be part of every Add-On Skill created for that class. When creating Add-On Skills, the Main Effect's skill level cannot be lower then the highest level you have previously generated for that Class- if you have generated a level 12 Gunner Main Effect, your future Gunner Main Effects will always be at least level 12, regardless of which Skill Creation option you choose.
