The Avalanche is a Hardmode melee weapon that is dropped by Cryogen. When the weapon strikes an enemy, it creates ice bombs around the player that travel in either the cardinal or ordinal directions. Each bomb explodes into four gravity affected ice shards on enemy hits or after 3 seconds. Each ice shards deal 50% of the weapon's damage.

Its best modifier is Legendary.


Used in


  • Despite appearing to be an axe, the Avalanche cannot be used to cut down trees.


  • Due to the way the projectiles spawn, this weapon is exceptionally effective against Worm AI enemies, as every one of the falling shards will hit their long body.


  • This weapon was previously known as the "Permafrost", but was renamed due to the introduction of the Archmage NPC, which will always be named "Permafrost".
