random loot generator (not understanding)

[pennywse]

I came up with a solution and it might help others that are having the same problem. Change the mysql values to your own and it should execute properly.

#::: Akka's Diablo Loot
#::: This script is designed to generate thousands of lootdrop entries to be dynamically assigned on top of an NPC's original loot.
#::: This script is ran pre-server-up once, or as many times as you wish until you feel like you have your loot the way you want it.
#::: This script has been designed to be ran as many times as you wish as it will purge all of the created entries each time you run it, only to create loads of new entries based on the new criteria that you have fed it.
#::: All criteria that this script uses is strictly specified in the table `cust_npc_loot_scale` that is shown below
#::: Example: perl DiabloLoot.pl
