I'm sorry for making an other thread about it but the previous one was marked as solved and people that replayed there kinda gave me some advices than actualy explain me how to do it
So i'll tell you what i know.
As fas as i know there are 3 was to nerf spells.
1 From DB in spell_data_bonus table but just some spells are handeled by database
2 Edit them directly from core but the thing is that I dont know c++ and i'm sure i will mess things up
3 Spell.dbc I know i have to edit the desired spell in spell.dbc on collom 81 to nerf or buff the spell. The thing is it doesn't seem to work in any way
For exemple i wanted to nerf the spell with Id 53408(this is judgement of wisdom) and in the original spell.dbc the number in the collom 81 was set to -1 so i changed it with -10 and then replaced the original spell.dbc file with the modificated spell.dbc then restarted the server but nothing was changed so i also put -10 in colom 80 and 82 because i thought maybe it's not the right collom and again replaced the file and restarted the server and again nothing was chamged.
I also tried to make a custom patch because i thought maybe that was the problem but it didn't work eather.
So please if anyone can explain me what i'm doing wrong or if i'm missing something would be really nice.
