### <mark style="color:yellow;">Notes</mark>

* **Block 0** = "primary" skills (basic/initial combo attacks). **Block 1** = "secondary" skills (follow-up combo attacks, typically stronger skills).
* Each line contains only the skill `Index` (the same `Index` used in `Skill.txt`) — the comment following `//` is for documentation purposes only and is not read by the game.
* There are no restrictions on the number of entries or duplicates. A skill may appear only in one block, in both blocks, or in neither (in the latter case, it will not participate in the automatic combo system).
