Gensokyo/Cirno

"I'm the strongest!"

Cirno is a Tier 3 Hardmode boss.

Spawn
Cirno may be summoned by using the Shimmering Snowflake in the surface part of a tundra biome.

Behavior
Cirno alternates between a movement phase and a stationary phase. She uses one of four spellcards, depending on her remaining health. While using her first spellcard, she attacks during both the movement phase and the stationary phase; with all other spellcards, she only attacks during the stationary phase.
 * Ice Sign "Icicle Fall": Cirno shoots Icicles to both sides, with the firing angle varying over time. After some distance, the icicles turn by 90° degrees, pointing them towards the ground.
 * Ice Clump "Cold Sprinkler": Cirno shoots massive ice clumps at a targeted player. The ice clumps in turn shoot smaller icicles. As the ice clumps rotate, the firing direction of the icicles also changes.
 * Ice Sign "Icicle Missle": Cirno shoots multiple salvos of large icicles in all directions. After some time, these icicles slow down and come to a stop. They then turn into large, stationary ice crystals. These need to be avoided while also dodging the salvos of Small Icicle Shards Cirno starts firing at players at this point.
 * Freeeze Sign "Perfect Freeze": Cirno randomly shoots colored orbs in all directions. After some time, she releases a wave of intense cold that stops these orbs from moving. Cirno fires a salvo of icicles while moving. Finally, the previously frozen orbs are unfrozen, after which they will move in a random direction.
