The Frost Barrier is a Pre-Hardmode accessory that can be purchased from the Traveling Merchant during a Full Moon or can be obtained from Ice Claspers. It is used to create the Auric Tesla Body Armor.

Being hit while wearing the Barrier will briefly debuff all nearby enemies with Glacial State, completely stopping them from moving. Both the range and duration of the Glacial State debuff are based on the damage the player took when the effect activated.

It also grants immunity to the Chilled debuff.


Used in[]


  • If players are having trouble finding one, wait for the Traveling Merchant to arrive and use a Cosmolight to make it a full moon. The merchant will remain at your house and his items will update to the full moon, allowing players to easily obtain the Frost Barrier.
  • If used with knockback immunity, it can potentially trap enemies in the player, killing them very quickly.
