The Frost Dagger is a rare secret drop from the Yeti and Ultra Yeti bosses on the Tundra map. Farm it on Normal difficulty, where the faster waves let you reach and kill more Yetis per hour without reducing your chance of getting the dagger.
The Frost Dagger is a melee weapon in Survive Zombie Arena that drops only from the Yeti and Ultra Yeti bosses during long Tundra runs. You cannot buy it, redeem it through a code, or pull it from a crate. Queue into Tundra on Normal, survive to the Yeti spawn waves, kill every Yeti variant, and repeat the run until the dagger drops. Below is the farming loadout, exact route, weapon performance, and final verdict.
Best farming setup for the Frost Dagger grind
| Slot | Pick |
|---|---|
| Difficulty | Normal |
| Map | Tundra |
| Class | Bastion |
| Gun | Lava Gatling |
| Artifacts | Cursed Doll, Soulforge Lantern, Chrono Core (plus a Venus Snaptrap flex slot) |
| Shelter | Deploy in a safe corner for the damage buff |
This farming build prioritizes speed and safety over maximum boss burst damage. Normal difficulty is the best pick because its waves move noticeably faster than Hardcore or Nightmare. You reach the Yeti spawns in far less time, and harder modes do not improve the drop. On Tundra, combine the Bastion class with the Lava Gatling for tracking fire that clears the horde with minimal movement.
Use Cursed Doll, Soulforge Lantern, and Chrono Core, with Venus Snaptrap available as a flex slot. The Cursed Doll trades -20% max health for +25% gun damage, which works well because you can keep buying health back. The Soulforge Lantern and Chrono Core complete the damage setup. Anchor in a safe corner, deploy a Shelter for its stat buff, and let the Lava Gatling’s tracking fire handle the waves.
How to get Frost Dagger from Yeti bosses in Survive Zombie Arena
Set up this route in the lobby, settle into a safe Tundra corner, and keep clearing Yeti spawn waves until the rare drop lands.
STEP 1/8
Choose Normal difficulty
Set the match to Normal. Its waves move faster than Hardcore or Nightmare, so you reach Yeti spawns much sooner and fit more boss kills into each farming session.
STEP 2/8
Build your artifact loadout
Equip Cursed Doll (+25% gun damage, -20% max health), Soulforge Lantern, and Chrono Core.
STEP 3/8
Swap to the Lava Gatling and Bastion
Equip the Lava Gatling and select the Bastion class for the extra damage.
STEP 4/8
Load into Tundra
Start a solo run on Tundra, the only map where the Yeti boss appears.
STEP 5/8
Deploy a Shelter in a corner
Take position in a safe corner and deploy a Shelter for its stat buff, then let your bullets auto-track the horde.
STEP 6/8
Hold for the Yeti at wave 75
Key Clear the waves until the Yeti spawns between wave 75 and 100, then kill it to roll the Frost Dagger drop.
STEP 7/8
Fight the Ultra Yeti at wave 150
Around wave 150, an Ultra Yeti can appear with 10M+ HP. Kill it as well because both Yeti variants drop the Frost Dagger.
STEP 8/8
Repeat until the Frost Dagger drops
Keep clearing waves and killing every Yeti and Ultra Yeti until the Frost Dagger drops. Each boss kill gives you another roll, making this a repeat-farm route.

How long the Frost Dagger takes to drop
Budget a long session for this rare drop. The successful route took a full day of grinding, with the Frost Dagger finally dropping around wave 1,600 after dozens of stages and repeated Yeti kills. A Yeti can drop only Credits and crystals, even on your first boss spawn. Drop rates vary, so treat this as a repeat-farm route.
The fastest approach is a sustainable, low-effort Normal run. Faster waves give you more boss kills per hour than a slow high-difficulty run, so you spend more of your session rolling for the dagger.
Frost Dagger stats, skill, and icicle rain attack
| Stat or effect | Value |
|---|---|
| On-screen damage | 21,010 DMG/sec |
| Skill | Backflip, then rain 15 aimed icicles |
| Charge gauge | ~50 (fills in a few kills) |
| Melee swing (tested build) | ~15,000 |
| Icicle hit (tested build) | 20,000–30,000 per icicle |
The item card lists the Frost Dagger at 21,010 DMG/sec. Its description identifies it as a secret drop from rare and Ultra Yetis: charge it with kills, backflip into the air, and rain 15 aimed icicles into the horde. The charge gauge makes the weapon shine. It needs only about 50, while other melee weapons sit around 100 to 150, so a few kills refill it and let you trigger the skill repeatedly.
The skill compensates for the lighter basic attacks. With this build, ordinary melee swings deal around 15,000 damage, while each icicle from the aerial attack hits for roughly 20,000 to 30,000. The backflip lifts you off the ground, letting you rain damage onto the horde while the zombies cannot touch you.
Once the gauge fills, stay airborne and keep clicking — the backflip loops as long as you spam it, chaining icicle rain while zombies can’t reach you.
Is the Frost Dagger worth farming
| Upside | Downside |
|---|---|
| Fast-charging skill (~50 gauge) | Base melee below top melee weapons |
| Aerial icicle rain gives strong crowd control | Long grind — a full day, around wave 1,600 |
| Backflip keeps you safe while airborne | No guaranteed or quick drop route |
| Low cooldown, spam-friendly loop |
Yes, the Frost Dagger is worth farming for its skill loop. Its base melee damage sits well below the top melee weapons, which hit for 60,000 to almost 70,000 per swing, but the fast-charging aerial icicle rain transforms the weapon. It delivers strong crowd control, protects you while airborne, and recharges after only a handful of kills. Builds centered on that repeatable loop get an 8.5 to 9 out of 10 weapon; the raw swing damage is secondary.
Other boss drops from the same grind
Long Tundra sessions also give you access to more boss rewards. The boss Guest 666 appears during the grind and drops Retro Crates when defeated, while the Yeti does not. Retro Crates can roll the Ban Hammer secret weapon, which has a steep 76,363 DMG/sec and is also buyable with Robux at a 0.6% chance, along with the Legendary Brickbattler Class. Kill Guest 666 whenever it appears during your Frost Dagger farm for an additional shot at those rewards.

Frequently Asked Questions
Can you get the Frost Dagger from codes or crates?
No. The Frost Dagger drops only from the Yeti and Ultra Yeti on Tundra. Codes give Credits rather than weapons, and crates will not contain the dagger. The crate-and-Robux route belongs to the Ban Hammer, which is a separate weapon.
Does harder difficulty improve Frost Dagger odds?
No. Raising the difficulty does not increase the Yeti spawn rate or Frost Dagger drop chance. Normal is the better farm because its faster waves let you reach and kill more bosses in the same amount of time.
What is the difference between Yeti and Ultra Yeti?
The main difference is health. A regular Yeti has roughly 500,000 to around 2 million HP, while an Ultra Yeti has over 10 million HP and spawns on later waves. Both drop the Frost Dagger, but the Ultra Yeti does not provide a higher listed reward chance; it simply has far more HP.
