Catfall is a variant of the psionic power Catfall, which in turn is based upon Feather Fall

• Instead of being enhanced by 50 ft per additional power point spent, the spell grants 50 ft fall reduction per caster level, as the power point mechanic does not exist for arcane / divine casters

Some clarity this spell does not slow down your falling but instead cushions you at the last minute?

Because I like that as an idea but then the duration makes very little sense. As Pathfinder assumes you fall at 500 ft per turn. I think we can blame the original spell for that.

For the rest i think it is good.

I'm also somewhat confused by the duration. Isn't the point of this spell to cast it when landing? In that case I'd say it's an instantaneous spell...

Nitpick: the spell has a somatic component, but the in the spell text calls the spell calls itself a "power" that you "manifest" with an "instant thought". This seems to the part of the psionic power text that is bravely resisting transformation into a spell.

This spell cushions you at the last minute. The duration is there as the original power has it, and I think takes into account that a fall may take multiple turns and this spell must be cast near the end of the fall. I have updated the manifest vs cast description

I have marked this spell as approved based on earlier discussion and its in game use
