@STAFF_Letitia just a question:
Isn’t Sandra just an Appraiser by default, and only becomes the Appraiser Master due to the player intervening?
So why is the NPC profile listing her as Appraiser Master?
The profile doesn’t even specificly state how she became a “Master” (in contrast to the other Class Master profiles) as the Class “Appraiser” doesn’t really exist in the world of Tree of Saviour prior to the player completing the quest.
So, wouldn’t it be better to either include the deeds of a certain saviour & her becoming an offcial master afterwards or just rename the profile to “Appraiser Sandra”, leaving the fact that she becomes a Class Master to the “goodwill” of the players?
Sorry for pointing out such quillets 
well people already did the quest so in the world it does exist, just that those who haven’t done the quest are in the past of those who have…
like any other quest xD
as for not telling how she becomes the master, it might be due to spoilers…
or…
plot hole
