On going SoM questions (and maybe answers?)

[Muffy]

I have so many questions I can't seem to find the answers for in the SoM guide, so I have took the libery of creating this thread.

Q.? ‎  I have this idea of creating a NPC that once you have healed him, he'll give you a map.
? ? ? I'm guessing I go into 'EVENT LEAF SETUP', but from there I get lost :(
... ‎  also, what is all this talk of 'counter'? example "Set Player Parameter In Counter"

Thanks
