Endless Ice Fangs

Ice × Spatial Magic: Endless Ice Fangs (氷×空間魔法『無間氷牙』) is an ice and space-based Union Magic spell.

Description
The Spatial Magic user touches their fingertips together and opens a spatial portal next to a target, through which the Ice Magic user spawns a spiky iceberg. The numerous icicles inflict blunt, cutting, and piercing damage. This spell could also be used to target multiple opponents at once by creating additional portals and ice.

Additionally, the ice freezes any surrounding surfaces, covering them in more ice and creating more icicles.
