Sodatsu no Oni

Sodatsu no Oni is a pulsating mound of flesh, constantly shifting its form and rolling over the ground like ripples of gelatine.

Its attacks are made by tendrils it can extrude from its shape at any given time. Those tendrils send blasts of magical energy or can create broad shields of energy. Those force fields will wear down any weapon and any spell cast toward the oni will be absorbed by the creature making it more dangerous and powerful.

The only course of action possible while fighting Sodatsu no Oni is to time the physical attacks. Sodatsu no Oni can only block or attack at a time. A group of bushi should then strike it on one side to divert the attention of the oni while another group will hit it.
