Personally, I'd prefer this to be built-in to the class feature, but barring that, here's a feat to give the monk's Slow Fall some extra coolsauce.
You have mastered the special methods used by sensei monks to slide down whole buildings and leap off bridges.
Prerequisites: Slow Fall class feature
Benefit: You can fall any distance without taking damage as long as you are within arms reach of a wall or other similar standing surface. When freefalling, you now take damage as if the fall were the listed slow fall distance shorter than it actually is (which means when you get "slow fall any distance," you can freefall any distance without taking damage).
Normal: Only falls made within reach of a wall have their damage reduced.
You sir, you make with the goodness. I like the goodness.
Why is there not a [class]thread for all things [class]ly?
