mvp that have set spawn:
Moonie, in the middle of Payon Cave 5, right below the budda.
LoD, This one have 5 set spawn point,
1. Top Left, Where you pass the first bridge and walk up and you see a house.
2. Kafar, Where the kafar, on the witch picture.
3. Middle left, Very near spawn point 2, you just walk left from the kafar and then you will see a path going down, LoD spawn on that path.
4. Bottom Right, Where Serin are located at (the sign quest)
5. Far Left, near the path that walks up to the witch house.
LoD will spawn his normal mob AND Loli + Bloody Murderer near him (though the Loli and the Bloody Murderer won't respawn and won't got summoned). And when he spawn, the whole map will spawn a lot of Dullahan(which have few on the map) and Disguise (which are never on the map except LoD is alive), and the extra spawn of Dullahan and Disguise will disappear once LoD is dead.
Gopinch, Top right, it seems that the hill is his cave.
TG, This one is like LoD, he got 2 set spawn point.
1. Middle of the map (like 80-90% of the time)
2. The room that on tops of the first spawn point, seems like a sleeping room to me.
Amon Ra, I think everyone know where he spawns at, in the middle of the map.
Drake, in his treasure room which is located at the top middle of the mini map.
Fallen Bishop, in the room where you read the books during the NI quest, (step 15 on irowiki NI quest)
Lady Tanee, I'm not sure of this one since i always see her in the middle of the map when I'm camping her, but then she teles right away upon spawn
I think that's all set spawn point mvp.
