Although its fairly easy to do this - Maybe some of you still dont know (and I didnt post anything for a long time :/).
For my example I'll use ABD but it should be nearly the same for other databases.
1. Open up your database via Navicat/Heidisql/SQLyog/whatever program you prefer
2. Open up the table 'pickpocketingloot'
3. Insert a new record.
Ill explain the different rows:
'index' - This one is just the index number of your pickpocket loot. Use a not already taken number!
'entryid' - This is the ID of the mob you want to have the loot. Use the entry ID from e.g. 'creature_proto' or 'creature_names'
'itemid' - Pretty self-explainable. Insert the ID of your item here (from table 'items')...
'percentchance' - The percentchance for getting this item. Insert 100 and the item will be in the loot everytime (100% :P).
'heroicpercentchance' - This is the chance for getting it if the mob is set to heroic (just insert 0 it doesnt matter)
'mincount' - The minimum amount of the item you will get by one loot.
'maxcount' - The maximum amount of the item you will get by one loot.
'ffa_loot' - Free for All loot - Insert 0 :P
Here is an example:
In this example the index is 121212 (I took a random, not already taken number),
the EntryId is 20000 so the mob with the entry number 20000 contains my loot.
The item is 7346 and he will drop it with a percent chance of 43,76%.
He will atleast drop 1 of the item and up to 3.
'heroicpercentchance' and 'ffa_loot' are always set to 0 !
I hope this helped some of you and if you got questions - PM me or reply in this thread (hey even if you dont have any questions reply please )
