Icefall

Icefall (直瀑) is an Ice Formation extension technique used by Uraume.

Description
This technique allows the user to lower the temperature around their hand and generate ice on any surface they touch. By freezing a surface with their hands, the user can generate large amounts of small interconnected sheets of block-shaped ice.

Icefall uses cryokinesis to allow the user to levitate the ice through the air and launch it at their opponent. It covers the target's body in a thick layer of ice on contact. Then the technique immediately rains down gigantic sharp icicles to finish off the target.

Usage
In order to put an end to the last rally of jujutsu sorcerers attempting to rescue Satoru Gojo, Uraume tried to kill everyone except Sukuna's vessel. Uraume activated Icefall by freezing the air around their hand and placing their palm on the ground. This created block-shaped sheets of ice woven around Uraume and Pseudo-Geto. Uraume telepathically commanded the ice to break apart and levitate toward their targets at great speed.

Icefall instantly froze Yuji Itadori, Choso, and Momo Nishimiya on contact. Once immobilized, the targets were nearly hit by giant icicles ready to rain down on them. Yuji was certain of his group's demise but they were saved at the last second by Yuki Tsukumo.
