Cryogen is a Hardmode boss that can be fought in the Snow or Ice biomes which possesses many phases and features a multitude of projectiles.
Defeating Cryogen will free the Archmage, as well as generate Cryonic Ore in the Ice biome.
Spawn
Cryogen does not spawn on its own and requires the player to summon it with a Cryo Key while in the Snow biome or Ice biome at any time.
Behavior
Cryogen has 5 / 7 phases, each of which has its own attack pattern and AI. It will progress through these phases as health lowers.
Cryogen also spawns with an ice shield which protects it and inflicts contact damage; this shield must be destroyed to directly attack Cryogen and will regenerate 18 / 12 / 9
seconds after being destroyed.
Cryogen enrages while the player is not in the Snow or Ice biome, greatly increasing its speed and acceleration. Snow and Ice biomes infected by the Corruption, Crimson, Hallow, or Astral Infection do not cause Cryogen to enrage.
Attacks
Phase 1
- Slowly chases and levels with the player.
- Fires an evenly spaced ring of 16
Ice Blasts every 2 seconds.
Phase 2
- Transitions at 80 / 85%
/ 100%
health.
- Attempts to fly above the player while continuing to fire bursts of
Ice Blasts.
- The amount of ice blasts is reduced from 12 from this phase onwards.
- After firing 3 bursts of ice blasts, briefly spins in place before charging at the player and firing 2 concentric rings of 10 ice blasts before flying up and resuming its pattern.
Phase 3
- Transitions at 60% / 70%
/ 80%
health.
- Slowly chases the player but stays slightly below the player.
- After firing 3 bursts of ice blasts, briefly spins in place before charging at the player and fires 3 concentric rings of 8 ice blasts. Cryogen performs this charge twice before resuming its pattern.
Phase 4
- Transitions at 40% / 55%
/ 60%
health.
- Slowly chases the player.
- Loses the ability to regenerate its shield.
- Fires
Ice Blasts at double the frequency.
- Every 5 seconds, Cryogen will teleport somewhere near the player and start attacking again.
- The location it teleports to is surrounded by a cloud of blue dust 2 seconds prior to telegraph its location.
Phase 5
- Transitions at 30% / 45%
/ 50%
health.
- Stops firing projectiles for the remainder of the fight.
- Rapidly and loosely accelerates towards the player, charging at them when it gets close.
In Expert Mode
- Regenerates its shield every 12 seconds instead of 18.
- Every 10 seconds, Cryogen releases a burst of 3
Ice Bombs. After these bombs hit tiles or 5 seconds pass, they explode into a hexagonal burst of 2
/ 3
gravity-affected
Ice Shards.
- This occurs in all of the above phases alongside other attacks.
- Velocity of the ice shards increases with every phase, and the number of ice shards created increases by 1 every 2 phases.
- Ice Bombs are smaller and cannot hurt the player or inflict status effects for the first 2 seconds after they are spawned.
- They also inflict the Glacial State, Chilled, and Frostburn debuffs but will not Glacial State if the player is already inflicted by the debuff.
In Revengeance Mode
- Transitions to Phase 2 at 85% health, Phase 3 at 70%, Phase 4 at 55%, and Phase 5 at 45%.
- Cryogen and its projectiles are slightly faster.
- Gains a new phase when at 25%
/ 35%
health:
- At the start of Phase 6, it slows down and spins for 1.5 seconds before charging at the player.
- Attempts to hover above the player.
- The
Ice Bomb attack no longer occurs every 10 seconds. Instead, a set of ice bombs is spawned every 1.25 seconds while hovering.
- It will also begin spawning 2
Ice Blasts with a weak homing effect at certain intervals.
- After spawning 2 sets of projectiles, it rapidly charges the player 3 times before repeating this pattern. While it will only spawn ice bombs during its dedicated attack, it can spawn homing
Ice Blasts during the ends of its dashes as well.
- When at 15%
/ 25%
health, its appearance will change 1 last time and its charges will each fire three concentric rings of Ice Blasts.
- The outer and center rings have 4 ice blasts, while the center ring has 8.

Summons
Aftermath
- Upon defeating Cryogen for the first time, Cryonic Ore will generate in the Ice biome.
- If at least two mechanical bosses have been defeated, Cryo Slimes will begin to spawn in the Ice biome.
- If the Archmage is not in the player's current world, he will drop alongside Cryogen's loot.
- The Rimehound enemy's stats are increased and will start dropping Essence of Eleum.
Notes
- While Cryogen is alive, the sky above the player is filled with a waving rainbow aurora effect. Unlike most screen effects from other bosses, it cannot be toggled off by lighting options in the Settings Menu.
- Cryogen's projectiles are colored deep blue during the day and white at night.
- All Ice Shards/Blasts are fired in fixed patterns throughout the fight.
- In the case of Ice Bombs, two spreads of three Ice Shards are fired when they explode, one in each direction parallel to the direction the Ice Bomb was moving.
- Cryogen will not fire projectiles if it does not have a direct line of sight to the player, with the exception of Ice Bombs. All of Cryogen's projectiles are also unable to travel through blocks.
- If Cryogen is close to the player when it enters Phase 5, it will briefly spin in place to give the player time to get away from its dash.
Tips
- For more elaborate strategies on defeating Cryogen, including weapon and arena recommendations, see Guide:Cryogen strategies.
- It is easier to see Cryogen's projectiles during the night.
- A wide arena with several levels of platforms can help in dodging Cryogen's attacks.
- Putting a roof of solid blocks above the platforms can help protect you during Cryogen's second phase.
- Be careful: Building platforms too far above the ground could cause the player to exit the Snow biome and enrage Cryogen.
- Moving at a constant speed will cause Cryogen to hover in the same place relative to the player, making it an easy target for ranged weapons.
- Moving slowly enough will cause Cryogen to hover directly above the player, this makes it very easy to hit, but be wary of its ice bombs and it potentially getting up close.
- Avoid getting hit by Cryogen's Ice Blasts at all costs as they will freeze the player, possibly leading to a swift death.
- Cryogen's final phase is one of its most deadly. If on Revengeance or Death Mode, saving Rage and/or Adrenaline to quickly finish it off during this phase could be a life-saving decision.
- While Cryogen is fought as the first boss in Hardmode, caution is still advised as the fast speed and many projectiles will make this boss tough for an unprepared player.
- In multiplayer, Cryogen does not despawn when off-screen and moves slowly across the map, allowing players to slowly kill the boss.
Trivia
- The
Bestiary entry for Cryogen: "When Yharim realized that the Archmage had defected, Calamitas was ordered to hunt down and kill her former mentor. After a tearful confrontation, she decided to instead seal him away, and fake his death. The spellwork present in this living seal is inspired, and a tragic homage to every lesson Permafrost taught his student."
- Cryogen's theme is Antarctic Reinforcement, which was composed by the artist DM DOKURO.
- The theme was called "Frostbite" in early production.
- There is a 1% (5% during April Fools' Day) chance that a status message will say "Cryogen is derping out!" when the boss enters Phase 6.
- Originally, this effect was guaranteed to happen.
- If the Boss Checklist Mod is installed, its unique despawn message will be "Cryogen disappears amidst the biting winds of the blizzard."
