IF "More..." appears in a commalist of mobs, items, or others, this means that the list was so large (>20) the wiki cannot render it, so we listed as much as we could and then added this to the end of the list. You can see the complete info usually on the source page for the Shop, or the treasure tables on the RoM-Welten database entry for this mob.
The "More..." may appear anywhere in the list if the list is sorted.
NOTE: This is because the commalist wiki function has a hard limit of 20 members.
