Slant consists of a single sharp 45 degree diagonal slash. The only thing that Slant differs from other 1-hit skills like Vertical or Horizontal is that Slant has a slanted trajectory and it can attack in two directions: either from top-right to bottom-left or bottom-left to top-right, the latter being the same stance as drawing a sword from the waist, thus greatly decreasing the time required to activate the skill.
As the skill can be used in two directions, it can be activated either by putting it on one's shoulder for a top-right to bottom-left slash or in a similar motion to drawing a sword from the waist for a bottom-left to top-right slash. The basic range of the skill is 2.5 meters.
Kirito used the skill to deflect the Magnatherium's claw attack, but the clash resulted in him being knocked back and smashing against a tree with his back, while the giant bear only had its attack stopped and its paw floating in the air from the momentum.
Eugeo used this skill to counter Humbert Zizek's Vertical. Although Eugeo's «Slant» was eventually broken, Eugeo's sword was pushed into a position that allowed him to activate «Vertical» and break Humbert's posture with it.
