Spellblade

“A strike that can be neither dodged nor blocked, thereby guaranteeing death. Fulfill these conditions within the one-step, one-spell distance, and you have what is called a spellblade.”

Lanoff Evarts,

founder of the Lanoff School of Sword Arts

Description
Spellblade is a technique unleashed from within the one-step, one-spell distance that will, without fail, kill the opponent. There is no way to resist them. There existed just six Spellblades till Nanao Hibiya created the seventh spellblade.

Known Spellbades

 * 4 th Spellblade:Angustavia—the thread that crosses the abyss. It belonged to Oliver mom but after her death Olive Horn borrowed it and can use it, he has to pay high tool from his body to use it and if he uses it three time in a row he can die from it. Sequential order is completely flipped when this Spellblade is used on its head. Instead of building up the present in the direction of the future, the user faces the predicted future and brings it into  the present. With the pull of destiny reversed, the rushing flow of time pushes its user toward a single outcome, drawing them to thier one-in-ten-thousand sword strike.


 * 7 th Spellblade:There existed just six Spellblades till Nanao Hibiya created the seventh spellblade. Her spellblade is an attack created when she needed to overcome the speed of light, an attack that supersede light itself - a blade that return all obstacles to the ether, a blade that can slice through formless space, the passage of time and everything else in between. The rules of nature forbid its creation, but she didn't consider even that and thus her spell came into being. An attack that cuts everything the user perceive as an obstacle between her and the enemy, even the concept of distance.

Weakness
It can only be activated within the one-step, one-spell distance so the user of the Spellblade can't use it beyond that distance.
