The 3x Multiplier.
You need a 900 point line to get it though. And maybe that's a pain.
But i got an easy way to get it.
All you need to do is anything related to a lazerflip (or just a lazer flip), add a 180/360 to it, land in a manual, revert it, then kickflip underflip out of it with a 180/360.
So that's: Lazerflip 180->Manual->Revert->KickFlip UnderFlip 180.
Thatll get you a 3 times multiplier for some huge points.
And mabey you can do it again with a 3x multiplier?
