This ability grants the Monk a one-time attack. To use this one attack, the monk must roll a successful attack roll; if he misses the attack is lost and the spell fails. If the attack succeeds, the target suffers points of 8D8 crushing damage and falls unconscious for 1 round. There is no saving throw against this part of the attack. Lastly, the opponent must make a saving throw against breath weapons at -4 to prevent from being knocked back for a considerable distance.
