When we go to wz in dangerous depths quest we need to spend points to be allowed to join during 8h, now, the usual amount of points is 15 per round, and basically, there's nothing in their dialogue that give us hints about how to reduce it, yet when u search for spoiler on some fansites it says that u could reduce the amount of device to 10 per round once you get the maximum rank of big foot's burden (1440 rank IV), trouble is... I have the points and I'm yet spending 15 points instead of 10 so,
What is actually needed to reduce the amount of points per round?
keypoints: I haven't done bosses from wz 1-2-3, none of them so idk if is a requirement.
I tried talking with all npc from both side, nothing of that work.
I tested and indeed Im spending 15 points per round no matter what.
