Freezing time HELP

[Yukaiii]

Good night friends.
Guys, I did a search on the forum, but I couldn't find a detailed explanation.
If someone could tell me how I can reduce the freezing time based on luk.

 

 

Would the modification be done right here?

        case SC_FREEZE:
            sc_def = status->mdef*100;
            sc_def2 = status->luk*10 + status_get_lv(bl)*10 - status_get_lv(src)*10;
            tick_def2 = status_src->luk*-10; // Caster can increase final duration with luk
            break;

Example: Normal freezing lasts an average of 10 seconds.
with 100 luk it would reduce it to 4 seconds frozen.

 

I've already tried a few ways here but none with success.

 

Thank you very much in advance!!
