The Cryogenic Staff's ice balls and area of effect icicle attacks. Notice how the fire rate of the ice balls increases the longer the sentry attacks an enemy.

The Cryogenic Staff is a Hardmode sentry sold by the Archmage NPC for 48 Gold Coin after defeating all the Mechanical Bosses. When summoned, the ice sentry fires an ice ball that inflicts the Frostburn debuff, as well as their rate increasing the longer an enemy is targeted. After targeting an enemy for three seconds, the sentry goes into a frenzied state, spinning around rapidly and firing ice balls with significantly increased fire rate as well as icicles in all directions.

Its best modifier is Ruthless. The Mythical modifier provides the widest array of stat bonuses, but these primarily affect the initial summon rather than the resulting minion. Additionally, minions cannot deal critical hits. The only lasting advantage a Mythical Cryogenic Staff has over a Ruthless one is knockback.


Used in


  • It can be very powerful against large, scattered groups of enemies aside from one specific targeted enemy because of the icicles.
  • Because it is a sentry rather than a minion, it does not consume minion slots and can be effective when fighting bosses for bonus damage.


  • The Ice Sentry's design was initially a redesign of Cryogen made by Cooper, a spriter and animator for the mod.
