spCategory Types
List of known spCategory types, which determine effect stacking behavior; which special effects are permitted to be active while other effects in the same category are also active.
| Value | Description |
|---|---|
| 0 | Permits stacking multiple different effects simultaneously, but forbids stacking the same effect multiple times. |
| 1 | ? (needs testing) |
| 10 | Similar to category 0, but allows stacking the same special effect multiple times. |
| 20 | Adding an effect that is already active will cause it to be reset. Notably, this resets duration. |
| 100 | Most recent effect added will remove older category 100 effects entirely. |
| 110 | ? (needs testing) |
| 1000,1002 | Effect with the higher categoryPriority will stay active. Lower priority spEfs are added, but will not activate as long as another effect with the same category and higher priority is active. If the higher priority effect is removed, the lower priority effect will become active. Higher categoryPriority values have lower priority. |
| 1001 | ? (needs testing) |
| 10000-10006+ | The first effect added will stay active, and any additional effects with the same spCategory will not be added. |
