Im sure most of us know this, but not many people do it. This is good for those who don't want to abyssea-burn their job completely, because then you'll have to worry about getting your skill cap up more and we all know thats a ***** to do...
But this is cool for people with pet jobs, and only in the older areas, which makes sense if you havent started lvling a specific job yet (youll find out why in a sec)
So I want to lvl my BST, it's lvl 1 right now, so this is my "party"
Myself
Trust NPC 1
Trust NPC 2
Trust NPC 3
Signal Pearl NPC
Charmed Pet/Avatar/Wyvern/Automaton (Obviously this depends on what job you use)
So NOW we have a full party of 6.. Cool right? And yes.. this works! The only catch is that you can't seem to use a signal pearl NPC in areas like the Seekers of adoulin zones. And you can't invite other players.. but thats the whole point.
COOL RIGHT? :D
