|Artwork for Perfect Freeze by Justazag|
It lets the user shoot a spray of weak ice bullets in a frontal cone area when the attack key is held, which pierce through exposed enemies and each deal two ticks of damage. If the attack key is let go while there are bullets on the screen, they will stop in place for two seconds, still being able to damage whatever comes in contact with it. One unit of energy is consumed for every fourteen shots fired, but if auto-firing it, the weapon uses four units of energy per second. As it is an ice weapon, Flame Pillars and Fire Walls can be frozen by it too, making them safe to touch.
- Perfect Freeze's individual shots has the lowest damage output of all weapons in the game that are still capable of dealing damage.
- This weapon, Croaker, and the song Wily Stage Cirnosis were the only content added in version 1.0.9 as part of the Cirno Update.
- Perfect freeze is one of a small handful of weapons that can inadvertently deal double damage to bosses per hit if the ice pellets are stacked correctly on top of eachother.
