I've been camping this for a few hours now. Always pops in the same place. The tonberries in the area are on a 5 min repop so it seems. And the jinxer could be a lottery and the nins and thfs placeholders, but something about that just doesnt add up.
Once it spawns again I'll see what it pops from, but at the moment killing thfs pops thfs and killing nins pops nins, but ive been killing for an hour with no blm spawn.
