I have spent this last morning assembling this Diablo 2 Pack for anyone who wants to make a D2 map. This pack includes 4 custom spells for each character (except for Assassin and Paladin, becuase of the editor at the moment).
Its free, just make sure u give me credit. Report any bugs to me here (I know about the Druid bug, I don't know how to fix it).
For wierdos who dont know how to get it into action, here's a step-by-step tut.
1: Open the zip file with WinZip
2: Extract the file to wherever u want
3: Open WE
4: Open the Object Editor
5: Click File>Import Object Data
6: Select the file
7: Test map (F9)
