Add some more damage on top of the knockback and slow as well as auto KO for mole hiding. Not worth it to get if it’s just a counter to mole hiding, as mole hiding is very easy to counter at the moment. It also requires heavy investment (2300 on both the doton chamber and crush, and 2000 more for a skill that’s primary use is to KO someone using mole hiding, which is rare and not that good to begin with) I feel like if the damage increases a little more the slow would be enough to push it into a skill people want, and maybe removing other earth jutsu as a prerequisite.
