How to Edit Beginner's Mega Pack or BOX/?

[naphy]

the box I am looking for is the (Beginner Mega Box) Here is the Item ID: 63496 So now How Can I edit what you get in that box after you right click it??? Where should I look at?? I go to GameServer/Slk/Script This the 3 Script I find there.
1. NpcScript
2. MonsterScript
3. ItemScript
I check the Item Script but the ItemID: is not there!!

What is this TreasureAward??? in GameServer/Slk/Treasure/TreasureAward?
But I dont think that this is the one I am looking for because in my Server I am using the EVOLUTIONBOI server file. and the award on that box is different on this TreasureAward.

Because what I get when I first open the box.. I get a Heart Exp 31x when I click it I become a level 41. then 30x left to be open once per day only etc... I want to edit that box.. Like in the BOIPVP when you create character and enter the game then open the box. You become a level 100 and that box contains Lv100 set gears.. I want to make like that

Inside of GameServer/Slk, there should be a file named Item. That should have everything listed.
