Description
At your first opportunity, use the Smash skill to nearby enemies. This powerful attack skill will send them flying. If your enemy repeats the cycle of repeating and defending at your coming onslaught, don't hesitate to seize the battle initiative by using a powerful skill like Smash.

Details
Attacks the target with one strong blow.
Higher rank increases the Damage of this skill.
From rank 9, this skill will start to add Str and Will.
At rank 5, this skill can cause Splash Damage.
The Radius and Angle of the splash is dependent on the weapon used.
Causes the opponent to fly back (distance 1000) and get knocked down.
Attacks through the opponent's Defense skill and still causes the opponent to get knocked down.
Countered when the opponent hits the user with normal attack (includes Windmill and Charge).
Countered when used against an opponent using Counterattack.
Also, a nearby player can use Counterattack and the Splash created will bounce back to the Smasher if the rank is at 5-1.
If two parties try to Smash each other (player vs. monster or player vs. player), the person with the better connection and/or most up-to-date attack order will be dealing the damage. You may have a better chance to do the damage if you spam the mouse attack button or enable Automated Combat mode.
This does not apply to Gremlins and Gargoyles because they have a very fast Smash animation. They will always win no matter what.
A few monsters automatically counter if Smash is used against them as first hit. (eg. Gorgons)
See Intuition for a further list.
Some monsters can "Fake" using Defense. They will walk toward the player with Smash loaded and will not execute after a few seconds.
Smash animation is dependent on your weapon and race.
Smash cannot be used with a bow equipped.
On rare occasions, a monster's Smash attack may be glitched. They will execute the skill, but the player will NOT be sent flying backward or receive any damage. However, the player will remain frozen in the stun animation, and will still be able to load other skills.
Note that if you try to Smash something when it is using Windmill, it will be stunned by the Smash animation but is not actually "hit" by the Smash. The smasher, however, will be hit by Windmill.
Sometimes when you try to Smash a target that's trying to get up, the monster will act like it received a normal hit, will not be stunned, and then may proceed to target the smasher.
