Updated Mainstream Mission Difficulty System

As we know by now, the system that decides the difficulty of mainstream shadow missions has changed. On the official site, it says that it was based on "current exp", but this seems to be an incorrect description of it.

I suggest that it may now be based on either Total Talent EXP, or Highest Level Talent (or its respective exp amount). This is in response to a forum thread that I saw claiming that a level 91 (total) character received an Intermediate mainstream mission rather than a Basic one.

If a level 1000 player didn't have any Expert-Level talent or higher, why would they need an expert level talent to do the mainstream Hard mission?

It's fixed due to renewals. It should not be predetermined by talent levels, nor current or total level.

Difficulty shifts are as follows:

• Basic up until the Secret Experiment Clue II in G9, in which it becomes Int.
• Int until G13 Hamlet, which should be adv from there.
• Advanced into the end of G16. There is no Hardmode.

Wait, there is no 1 predetermined mission difficulty for every mainstream quest? There is no more scaling?

I think a few exceptions apply, like Jenna's RP on Basic and what not. Unless it is mentioned, it will assume the difficulty level placed as of the renewal back during G17S4, which I mentioned earlier.
