try

item script:

{},{ char_variable++; },{ char_variable--; }

and npc script:

-    script something    -1,{
OnPCStatCalcEvent:
    if(isequipped(<itemid>)){
        skill <"skill name">,char_variable;
    }
end;
}

 

this might work without npc

{ skill <"skill name">,char_variable; },{ char_variable++; },{ char_variable--; }

item_combo_db.txt:

 

Item_ID1:Item_ID2,{ bonus2 bSkillAtk,"SKILL_NAME_ID",100; }

Example:

4117:4117,{ bonus2 bSkillAtk,"AC_DOUBLE",100; }
