Resources[edit | edit source]

The freeze execution during this boss fight isn't very impactful for the required resources you need, but if you go for the 2-bomb pattern on Star's first spell, it helps to get 30%s during this spell. It's recommended your first run just focuses on doing a 1-bomb pattern on this spell.

If between the start of the game and Star's first spell there's been one death, you can switch to the 2-bomb pattern on Star's first spell if you planned on using 1 bomb. You would be 25% PF ahead from the death and you would waste this PF by not doing an extra bomb on Star's first spell - you reach 300% PF by the time you reach the Stage 2 midboss, where the next bombs are used. To make up for the lost motivation, you will be skipping one suicide on Luna's first spell.

The preferred minimum resources to end Star's fight with are 525% Motivation and 180% PF.

Nonspell 1[edit | edit source]

The simplest part of the game. Pointblank the ring Star fires and start moving diagonally down in focus speed for roughly 1½ seconds (while charging) towards the nearest side of the screen. Stop moving after the 1½ seconds so long as you're hugging the side of the screen and then freeze the bullets right before they can hit you.

Star's positioning usually doesn't influence the execution you should be doing, but if Star is positioned low and in the middle of the screen, you should position yourself slightly away from the wall before freezing the bullets as this prevents the bottom bullets from going offscreen.

The last freeze should be done just before the timer hits 1.00s to maximize the size of the freeze before the bullets are fully deleted.

You can sideshoot Star inbetween waves, but depending on Star's positioning, some freezes will do more damage than others and too many high-damage freezes can cause the nonspell to die early if you did too much shot damage.

This spell has alot of RNG. The general way to approach regular freezes is to get your freeze to release between two lines of stars that are as far away as possible, but still get frozen by Cirno's ice. This allows for the most amount of horizontal spread and coverage.

How much the ice expands upwards is luck based and therefore the ice damage is too. Star can't take too many full DMG freezes or she'll die several freezes early. Therefore it's important to try to activate freezes in places that are horizontally away from Star to do less ice damage to her. When doing the second bomb (in a 2-bomb pattern) you can do a shorter (50%) freeze to get a small amount of PF before doing the final bomb. The second bomb should be done at or right before the timer hits 3.00s, as the bomb lasts for around 2.80s.

While preparing subsequent freezes, you can ice graze bullets while the old freeze effect is still going, sideshoot Star for as long as she isn't moving and graze stars while charging.

Nonspell 2[edit | edit source]

Pointblank the first ring and freeze the backside of the second ring when it passes about two player character heights away from Star. This will do full ice DMG to Star while maximizing the ice area. When doing partial DMG freezes to Star, time the freeze slightly later. Some of the freezes have to be partial damaging in order to not kill the nonspell too early. The sideshooting on Star should be very minimal here.

If your Ice Power is about 30% or less by the time the first ring spawns, try to also pointblank graze the second ring. This doesn't have to be done aggressively but enough to where you'll have at least 90% Ice Power by the time you're supposed to release the ice.

Star Sign "Red Star"[edit | edit source]

Each freeze here should preferably be charged to between 80% and 100% Ice Power. Then activate your freeze right before Star starts moving, as to not waste too much time with the freeze not freezing new bullets. After releasing the freeze, dash forward, diagonally or sideways depending on how much HP Star has left. Ideally you do no more than 1 or 2 full DMG freezes before getting to the final freeze. The rest should be partial DMG or no DMG freezes.

A small optimization is to move upwards before activating your freeze, as this bunches the stars more together due to how the rings of stars spawn. Freezes also yield slightly higher area by dashing diagonally rather than up, left or right.

Something to be careful about when dashing during the freeze is to not instantly dash upwards when releasing the ice, as doing that risks you to ram into a bullet before it gets frozen. Wait a small fraction of a second before dashing. When doing a freeze while moving sideways, also be careful of leftover bullets that aren't getting frozen.

If during this spell you unintentionally die and you were doing a 1-bomb pattern during Spell 1, you can use an extra bomb on this spell.
