How to Remove npc ?

I want to remove Npc from Loa Castle map.

data\share\map\07_loa_castle\npc_07_loa_castle.csv

lmfao, anything that's inside share/map/ all maps are in there. npc_loa and search the index of what one you want to remove. you can find any of these indexes in share/creature/npc.csv
