NPC health and exchanging knowledge?

[nuitwaters]

Two quick questions for my fellow homins here:

I plan on making a scenario that involves the player with freeing Trykers from Matis control and I want to have the player actually fight with the NPC Matis Guards/Civilians.
I hope to look at this more tonight but has anyone run into issues with this? I see that I can change the level from Low to high on these NPCs but I wanted to create a solo dungeon run for some of the newcomers (or returnees like me).

Also, my old main character has some insane knowledge of Atys and has about 20 maps available for each zone to create a ring in while my freebie has 4 basic maps. No way to share this information between characters, right?

Excuse the basic questions but I'm bored at work today and want to talk about Ryzom until I can get home to play again.
