Ice-Make: Ice Impact (氷撃の鎚 Aisu Inpakuto) is an Ice-Make Spell.
Description[]
The user brings their right fist down on their left palm, creating a massive, intricately-designed hammer made of ice, with ice spikes at the head. The giant hammer is brought down onto the targeted area, creating a great impact upon contact.[1]
In the manga, the hammer's appearance has differed between uses. In its initial use, the hammer's handle and head was decorated with much more spikes. When used against Silver Fullbuster, the design is much more refined in appearance.[2] In the anime, the hammer had a unique appearance as well, lacking spikes and featuring a drill-shaped head.[3]
