Breath of Winter is the legendary tier crate weapon that could have been opened from the Winter crates. It is a knife with the blade's design consisting of a frozen ice block. It has a more pointed edge than the regular shop knives, and a differently designed hilt and handle sharing the design of the blade. For its effect, ice clouds ascend to the top of the knife before disappearing. It has normal range and sound effects if equipped when playing as the killer. Players had a pretty low chance to get this due to its tier.
