The Frost Blaster is a tower that pierces through and freezes any enemy hit by its projectile. It could have been unlocked by triumphing Village of Despair during the Christmas 2019 Event. It could have also been through a limited time gamepass for 350. It was most recently available again for 525.
The Frost Blaster starts out with decent damage, gaining more damage at higher levels and it also has a somewhat high firerate. However, it fires piercing projectiles that freezes enemies when hit. Any enemy with the Freeze Immunity cannot be slowed down, frozen or have its Defense dropped by the Frost Blaster. This makes Frost Blaster an offensive support hybrid since it has a higher DPS than the Freezer.
Starting at Level 2, the Frost Blaster will melt 15% defense every tick, though it can only decrease an enemy's defense by 33%. For example, if an enemy has 50% defense, it will be decreased by 16%.
The Frost Blaster is mostly considered as an early to midgame tower, though it can sometimes be considered as an all-around tower. Its relatively low-medium placement cost and decent DPS can be useful in the early game, while its later upgrades and relatively higher DPS can be sufficient in the mid to late game. Though, this tower should mainly be used as a staller and crowd control tower due to its freezing and piercing capabilities. The Frost Blaster has a placement limit of 12 per player.

Statistics
To see all the previous statistics of this tower, see the history page, while for the statistics without the Firerate Bug.
The Frost Blaster's piercing projectile makes it a great tower for early and mid-game.
For earlier waves, a Level 0-2 Frost Blaster can be effective at killing enemies that spawn, though by the time high health singular enemies spawn, like the Elite Abnormal, it should be upgraded to Level 3 because of its higher DPS and better chilling
Later on in the game the Frost Blaster does not have enough DPS to deal with enemies like the Fallen Giant or Hidden Boss on its own, meaning that you need other towers alongside it.
It can, however, be useful at chilling enemies and decreasing their Defense.
Unlike other freezing towers, the Frost Blaster only chills an enemy.
Larger enemies, like the Fallen Giant will get slowed down for a shorter amount of time. Additionally, it cannot slow down any enemy that has the Freeze Immunity.
It can still apply the chillness slowdown effect to Boss enemies, as long as it does not have Freeze Immunity. However, the slowdown effect will be much weaker.
The Level 3 is especially good at slowing down, as its freeze time and firerate are nearly identical, allowing to close to permanently slow down smaller enemies.
The Frost Blaster'sDefense melting ability can be useful for decreasing an enemy's Defense, allowing your towers to deal more damage to it.
However, do note that as the defense melting happens when an enemy is slowed down. Because of this, freeze immune enemies cannot have their defense melted.
The defense melt can stack with other towers, such as the Pyromancer, Electroshocker or Toxic Gunner, allowing you to remove an enemy's defense entirely.
However, the Frost Blaster's defense melt does not stack with other freezing towers.
The Frost Blaster's range is quite high at Level 4, making it harder for enemies to get out of its range.
This also means it is able to chills enemies from far ranges, surpassing many other stalling towers in this regard.
You can use the DJ Booth to increase this already high range even more.
Because of the Frost Blaster's freezing and cheap hidden detection, it can be used against early hidden enemies like the Fallen Soul or Hidden.
However, it may be best to upgrade a single one to Level 2-3 or place multiple Level 1 Frost Blasters as a single Level 1 Frost Blaster is unlikely to deal with them on their own, especially against Fallen Souls.
Later on, Level 4 Frost Blasters are effective at freezing high health hidden enemies like the Hidden Boss, Elite Phantom and Elite Soul.
The Frost Blaster is effective against Leads and Elite Leads as it has lead detection from Level 0 and can freeze them.
The Frost Blaster should be upgraded to Level 2-3 or have multiple lower levels placed down because of their high health.
Trivia
The Frost Blaster received its first and only skin after 2,481 days.
The SoldierBeach skin was originally made as a Frost Blaster skin, however, it ended up getting converted into a Soldier skin instead.[3][4]
Certain parts of the design like the Frost Blaster weapon look did get carried over to the Soldier version of the skin.[5]
