[DevilSupremeRO]

i dont know why this dosnt affect lvl 255 but if a lvl 1 novice coma takes effect can anyone? i already tried 10000 before and turned it back to 100 since it didnt work

case 9: // DEATH - curse, coma and poison
    {
        status_change_start(src, target, SC_COMA, 100, skill_lv, 0, src->id, 0, 0, SCSTART_NONE);
        sc_start(src, target, SC_CURSE, 100, skill_lv, skill_get_time2(status_sc2skill(SC_CURSE), 1));
        sc_start2(src, target, SC_POISON, 100, skill_lv, src->id, skill_get_time2(status_sc2skill(SC_POISON), 1));
        break;
    }
