1. Rathena forum do make use of search function and question is did you know it's located at top right of the forum page ???
2.  Search first before you even do the asking.
3.  you request might go unanswered if it's already answer.  or it's everywhere already.
 

A few things you will need:
 
-%TAB%itemshop%TAB%<NPC Name>%TAB%<sprite id>,<costitemid>{:<discount>},<itemid>:<price>{,<itemid>:<price>...}

*callshop "<name>",<option>;
 
check >> Rathena/doc/script_commands.txt  for explaination

This method is easier comparing to recompiling lolz.  comparing to editing database .txt all around
and this method is fully changable to event script's need easily..(on the fly changes)
 
Sorry for the broken previous script but this script tested working in current rathena version.
Put this part inside your npc files.
function script F_RBox { // change Item ID here setarray @i1[0],607,608; // Common Items setarray @i2[0],512,513; // Rare Items setarray @i3[0],514,515; // Super Rare Items set @i1rand,rand( getarraysize(@i1) ); // Randomize Common Items; just change max amount if you add items set @i2rand,rand( getarraysize(@i2) ); // Randomize Rare Items; just change max amount if you add items set @i3rand,rand( getarraysize(@i3) ); //Randomize Super Rare Items; just change max amount if you add items .chance = rand(100); // Super Rare Item 1% if (.chance == 1) { getitem @i[@i3rand],1; announce "["+strcharinfo(0)+"] won a ["+getitemname(@i3[@i3rand])+"] from the Super Rare Box.",0; end; } // Rare Item 10% else if (.chance <= 11 && .chance >= 1){ getitem @i[@i2rand],1; announce "["+strcharinfo(0)+"] won a ["+getitemname(@i2[@i2rand])+"] from the Rare Item Box.",0; end; } // Common Items else { getitem @i1[@i1rand],1; end; } } Note : above script is to be inside any .txt which are loaded in your npc folder

custom skill? casted by this "1872"?
1. Try disguise 1872 or 1874 again to confirm it's not sprite related.
2. open mob_skill_db or any monster skill db 
when in there open your server and run your client 
inside your client 
use @skill SKILLID
where SKILLID is all the skill of that 1872 and 1874 monster
if you don't understand this procedure ask someone to explain to you, because I can't explain in other way than this.
 
3. If it is custom skill you need to fix that yourself unless you post what your code or changes for your custom skill here to let people inspect on it.
 
 
 

Remove this!
 and disregard

dispbottom instead of dispbotton???
 
Update:  Should be good.
 

Change the item's Aegis name
Eg:
Item 1:
xxxx,SuperduperCustom1,ItemNameCustom1,....
Item 2:
xxxx,SuperduperCustom2,ItemNameCustom2,....
Item 3:
xxxx,SuperduperCustom3,ItemNameCustom3,....
