Like, say, for an example, if I wanted to spawn kyle_boss with dual lightsabers of any kind, is that possible? Anyone know how?

I think there is a way to alter the NPC's script file, giving him dual sabers/saber staff.... .etc

Open up assets1.pk3 in Base folder and go to ext_data/npcs. There look for the NPC name you want to edit. Extract out the .npc file to desktop and open with Notepad. Once you open it look for the line where it tells you which saber type the NPC uses try changing it.

Ah, yes, that's what led me to NPCTool.. thanks anyway though.
