Spell category tab in Spellbook

[Kiun]

Hi,

I'm trying to change category tab of one spell in the spellbook, e.g. Concussive Shot of hunter is in Marksmanship spellbook tab, I want it in Survival spellbook tab.
The problem is that information is not managed in Spells.dbc and I looked for other .dbc and can't find it. The SpellCategory.dbc has only 2 columns: ID and field1. But Field1 is full of 0...
I have been looking for it in world SQL tables but it isn't there either...

Any ideas?

Thank you!

EDIT: Solved, it's not SpellCategory.dbc, you have to edit and SkillLineAbility.dbc according to SkillLine.dbc
