Icicle Lance

"Icicle Lance" is an Elemental-Based Magic Spell.

Description
A sharp rod of ice is created and then launched at high speed. Icicle shotgun, a bunch of small ice particles are spread across an area. They solidify into large crystals of ice, similar to how ice is created around a single particle. Then they all launch towards enemies. It is strong against fire based enemies as demonstrated in episode 7.

Adaptation
It is used in Chapter 10 by Elyune against Shizue Izawa (when Ifrit took over her body). It is eaten by Rimuru, who then develops a variation known as "Icicle Shotgun".
