[Autumn]

Dense thunder doesn't knockback at all but inflicts sound damage still (even not up against a wall), also it only consumes 1 ki

The sound damage from Dense Thunder only effects the initial target, and has as many instances as there are monsters around it.
(Fangs surrounded by 2 jellyfish took this from dense thunder)

Asa Risa's turn.
