Earth Release: Blood Stone Technique

A technique in which the user accumulates and condenses mineral composites in the ground, before manipulating them in such a manner that they rise up in the form of earthen stakes. Since multiple stakes are created by this technique, which erupt from the earth concurrently, following the target as they move, it is a monumental task to evade them. Furthermore, if the target is pierced by the rising stalagmites, a malignant aggregation of rock will form inside their body, which continues to spread throughout the target's body until they killed from the inside out.

Trivia
