The Sky Mantis Scythe's effect will treat you as though you were on the ground when you basic attack even while you are airborne meaning you NEED airborne compatibility from a Corbie's racial for it to actually work.

I don't think this is intentional considering that this weapon is supposedly Alstalsian and the zerans aren't great at flying.

Below are a series of screenshots that show that it's not actually reducing momentum for a basic attack whilst airborne using leaping lizard and at 7 momentum.

Just make the Scythe grant https://sl2.wikia.com/wiki/Stay_Afloat, since the scythe is not really 'that' amazing or OP anyway. Two birds with one buff.

It shouldn't break your airborne status anymore.
