maybe its been done b4 and maybe not. But heres my little contribution to mmowned. I was looking to make a mall guard that would attack any player that starts up a pvp fight. Flexible Database Editor was all i had. they said it can only be done in C++. Now i will show you an easy way to do this and all you need is heidi or navicat.
step 1 - go into heidi or navicat and search under creature_proto for 9460. change its health to a stupid ammount and dammage to another stupid ammount.
Step 2 - restart server, log in and spawn npc 9460 at the mall or where-ever and wait for someone to pvp
step 3 - watch them die very quickly upon attack
have fun.
and yes it works with Re-packs
