Translations:NPC Placement and Alignment/106/en
From DragonMineZ Wiki
All four threshold fields are optional: leave out whichever don't apply. Reading the goku entry above as an example: below 25 alignment Goku is hostile; from 25 to 60 he is present but won't talk (the alignment is under the min_alignment of 61); at 61 or more he is friendly and can be talked to.
