Deltarune Chapter 2 - "theoretically" using Snowgrave to kill a bunch of enemies.
A sorts of continuation of the previous video.
While obviously the Thorn Ring was cheated because every enemy needs to be frozen before Berdly's fight, Noelle having Snowgrave in her spells selection is 100% legit; the only requirement is to defeat Berdly with violence and because of that, from what i can guess, thanks to some flags not correctly updating, the lethal spell will always be available in the menu.
