IceShock

Kris, it looks like another enemy.
Should I freeze them?

Noelle, Weird Route, Chapter 2

IceShock (JP: アイスショック) is a spell in Deltarune, usable by Noelle. By default, it costs 16% TP, but this can be reduced to 8% TP if the ThornRing is equipped. It is an attack that does a significant amount of damage to one enemy. When using this spell, Noelle creates blue stylized snowflakes on the targeted enemy.

Main story

IceShock is available starting from Chapter 2, when Noelle is found in Cyber City and joins the party. It becomes unavailable when she leaves the party.

After finding Noelle in Cyber City, every enemy encountered in Cyber City must be frozen with IceShock to access the Weird Route.

At the end of the Weird Route, when Noelle is called for help, she presumably shows up after the screen goes dark and casts three IceShock spells on Spamton NEO.

Mechanics

IceShock deals damage using the following formula:

(Magic - 10 can only result between 1 and 999)

IceShock freezes enemies solid when defeating them, instead of allowing them to flee. They remain frozen in the overworld once the battle ends.

Trivia

• On the Chapter 2 Weird Route, Noelle suggests using a spell known as "Iceshock" against a boss in Dragon Blazers III.
