The Lucky Find is free for all races to access, including surfacers ( : ))))))))) ), but not drow, or, at least, not easily or at all for most drow, since it requires you to beat a diplomacy check of 30 or 35, I forget which. Drow are free to interact with all svirfs in the village, including the quest givers, without any restrictions due to the custom lore for Rockrun, except for the one NPC who runs the *potentially* best shop in the whole Underdark.
In the words of another player whom I've just told about this, it seems to be "some <word censored by OP> joke".

Could this check be removed please?
