Magician %/s (KMS FLY 2 & GMS Dawnveil)

There seems to be a negligible difference between the last and next to last, but a difference nonetheless. Seems weird.

Also theoretically, I thought Mist was included in the stacking. So a combo of Mist->Para->FD->PB->BB would be 5, not whatever is after Mist. So if that's the case, the damage should stop significantly increasing after your 5th picture (4_11.png), not after the 6th, but it does increase, and a lot. It would seem like Mist is not counted in the stacking to bring up ME's damage, so Para->FD->PB->BB->Meteor (with mist already set and not included) does work. Could the skill description be incorrect/misinterpreted by one extra skill to stack?

Now I'm wanting to test this out myself too.

I always assumed Mist was included in the stacking. I seem to remember testing it out and the enemy, hit by Mist's initial attack, had more damage dealt to him than the enemies not affected by Mist's DoT. But I haven't tested this recently, and I could be mistaken.
