BTW I think there are multiple factors acting on an NPC's leveling up. Killing things may be one but I think actions effect it as well.
People have said there is a "lag" between kills and leveling, often. I think that this is due to EXP or some other factor towards NPC leveling - because no one knows for certain that NPCs even level in the same EXP-based system that we do - which is gained from performing actions.
This happened for my first level up:
When I was with my NPC in yhoat as healer type, I killed a couple of white lizards at one point and had to rest. I sat down and so did she. She was still level 30 at this point. I waited till she was all ready, got up, and after a bit of running - just a few seconds, we hadnt faught anything since I rested which must have been a couple of minutes back - she cured III'd me for what I hadnt rested back and pow, she levels up! No delay after the action either.
I can see no reason why this might have been "delayed" from our previous kill, it really seems as though this action - which is core to a healer type - leveled her. I dont know for sure though, of course. Killing mobs may very well give bigger chunks towards a level though. Or perhaps only for "attacker" types? Leveling may be different between styles, and there is nothing that really indicates NPCs have the same leveling process as PC's. We KNOW that NPCs don't have jobs identical to the PC ones because no PC job combination can wear a Seer's Tunic and wield a GKT, for instance.
And Inuakurei, no need to get offended. I'm not saying your input isnt valuable or that you're definitely wrong, just that I disagree. In fact I CANNOT say that what you are saying is wrong, because there is very little concrete evidence at all here. I am merely saying that I disagree on one or two of your points.
