How do I decrease the crystallization status on Diamond Dust skill?

[Peonie]

Please help! What should I change to decrease the chance rate of the crystallization/freezing status?

 

case SO_DIAMONDDUST: rate = 5 + 5 * skill_lv; if( sc && sc->data[sC_COOLER_OPTION] ) rate += (sd ? sd->status.job_level / 5 : 0); sc_start(src,bl, SC_CRYSTALIZE, rate, skill_lv, skill_get_time2(skill_id, skill_lv)); break;

Uh, there it is:

rate = 5 + 5 * skill_lv;
