First of all, you'll need a few things.
WoWc - http://rapidshare.de/files/19316603/WoWc.rar.html
WPE Pro - http://m0001.gamecopyworld.com/games/gcw_game_tools.shtml
And the server files, since I'm making this for someone who plays on an AFG Repack server, here's the link - http://rapidshare.com/files/2701611/AFG_MEGA_REPACK_V3.rar.html
Note: WPE is a harmless trojan, used to send and recieve packs.
Ok, moving on. In the left hand column double click filter 1, change the name to 'Scrax's Plasma' or something of that sort. I saved it so I don't have to find the ID again. In the Search row Offset 15 put 8A and in Offset 16 put 42. And in Modify put 10 in 15, 4E in 16, and 01 in 17. Apply, save it if you want. Select WoWc, check the little box, and press on. Then go buy a Maple Seed from a Druid Trainer.
Offset: 15 16 17
Search: 8a 42
Modify: 10 4E 01
To get ID's you'll need the scripts. Open the server files, go to scripts and open the .scp file with notepad. The best places to find items are under Chronos -> Items and AFG -> Items. Of course these are only the custom items on that repack. Edit -> Find or Ctrl + F to find items quickly. Once you find what you're looking for, open calculator. Goto View -> Scientific. Put the ID in decimal form then convert it to hexidecimal. You would enter it backwards, it's kind of confusing so I'll give an example.
Scrax's Plasma Blaster ID Number: 85520
In hexidecimal: 14E10
So you would enter that in as 10 4E 01, starting at Offset 15 and ending at Offset 17.
