It works with any class with less HP or for that particularly fussy Lawful Paladin "Ladders are for Paladins, real warriors jump!!!"Next time I play that class, I will use that quote.
"Ladder?! Ladders are for wizards! Wraaaaah!"
You can also do "Stairs?! I don't need no stinking stairs!"
And in a rage you take half damage from the fall anyway. 1d6 Bludgeoning Damage per 10 feet fell so you could fall like 30 feet and take on average 5 damage.
