Very nice pack, I got it working with no issues (I use L2jMobius' patched system to connect as 99.9% of Interlude servers are the same anyway).
Fake players system works well but seems to only support 3 classes, Archmage, Spellsinger, and Storm Screamer.
Adding more classes to the source code should be easy except the fact that I don't want heavy armor classes and light armor classes to be wearing robe with staff making them unable to use any abilities.
Any ideas?
