I don't wanna destroy the fun here, but its impossible get 100% of all rl npc and work 100%..
there are so extremley many npc.. and there are alot of hidden too... some known npc even have hidden functions none ever chould belive..
There is hidden npc down in poh. under the ground, think there is like 5-10 npcs down there...
and in Ankrahmun there was atleast 2 npc I've spotted down there, dunno function of them thought, didn't test em..
there are Hidden npc under Venore.. Etc, etc.. and so on.. that whould like take a whole life for a "Absolute no-life" dude to complete..
(find npc, make outfits mabey aint hard, but functions.. and ofc the hidden npcs)
