Permanent NPC and cutom Buffs

[jeditigger]

First off I am new to this private server thing. I have a server up and running and have a couple of questions if someone can answer.

How do I make a permanet NPC in my world? One that will stay regardless of server restart.

Is it possible to design custom buffs? And is it possible to have a NPC cast any of these custom buffs on players that request them (right clicky)

My purpose is to allow 5 man parties request these temp buffs that will allow them to take on typical raid like dungeons. In theory make them (for example) 32times more powerful allowing them to complete the encounter.
