The Abyss Event 4

SHA-BAM! 

Uno landed in the midst of the void monsters, flattening many beneath the sheer force of his weight, while others got blown away by the sharp shockwave that erupted from his attack. 

The Epic skill Hard Landing made the user jump into the air and angle down to smash the ground with extreme force, converting the character's weight and Strength stat into raw damage values with an x10 modifier at Rank 2. 

The heavier your character and the higher the Strength stat, the more powerful this skill.
