Survive Zombie Arena: How to AFK Farm Bosses for the Frosted Dagger

The Tundra map update in Survive Zombie Arena added a boss that drops the Frosted Dagger, a rare weapon. You can farm it hands-off by clipping your character into a safe map position and letting an auto-clicker fire for you while waves and bosses spawn. The setup depends almost entirely on the Bastion class and its Shelter gear.

Quick answer: Equip the Bastion class, deploy a Shelter into a wall or under the map on Tundra, Atlantis, Prison Yard, or Abandoned Farm to become invincible, then run an auto-clicker at a 100ms interval to keep shooting while you are away.

What you need before farming

The whole method is built around one class. The Bastion is a Legendary defense class that costs 100,000 credits, and its Shelter gear is what makes you invincible. Deploying a Shelter in a match costs 1,000 crystals, so farm that amount first on maps where you need it.

The Shelter is a placeable fortress. Players standing inside it become invincible, regenerate 4 HP per second, and gain a +10% damage boost. Placing it partway into solid geometry is the trick that clips your character inside walls and terrain.

Requirement	Detail
Class	Bastion (Legendary, 100,000 credits)
Key gear	Shelter (Rare) — invincibility, +4 HP/s, +10% damage
Shelter cost per match	1,000 crystals to deploy
Recommended weapons	Plasma Gun, Blood Pistol (2,900 DMG/sec), or Blood SMG (6,000 DMG/sec)
Auto-clicker	OP Auto Clicker 4.1 at a 100ms interval

For the auto-clicker, set the click interval to 100 milliseconds, mouse button to Left, click type to Single, and repeat until stopped. This keeps your weapon firing while you are away from the keyboard.

Tundra glitch for the Frosted Dagger

The Frosted Dagger drops from the Tundra boss, so this is the map that matters for the new weapon. The mountain wall gives you a fully safe pocket.

Climb up the gray mountain wall at the edge of the arena.

Place a Shelter so that it sits partially inside the mountain face rather than flush against it.

Enter the Shelter to clip your character inside the mountain. From there you are safe from all ground-based zombies, so you can leave the auto-clicker running while waves and the boss are cleared.

Other safe map spots

Three more maps have reliable safe positions. Two of them use the same Shelter clipping idea, while Abandoned Farm relies on a terrain seam instead.

Abandoned Farm

Walk to the dirt seam near the crops.

Turn on shift-lock and slide backward into the seam to slip underneath the map.

Shoot upward to kill zombies from below. This spot is not fully safe, since flying zombies can still reach and damage you.

Atlantis

Farm the 1,000 crystals needed to deploy your Shelter, then move to the green test tube wall.

Stand against the test tube and place the Shelter directly into the wall.

Enter the Shelter to clip inside the wall, where zombies cannot reach you.

Prison Yard

Place a Shelter near the outdoor gym equipment.

Jump in and out of the Shelter three times in a row to trigger a large jump boost.

Use that boost to land on the building’s roof, walk to the edge, and jump off to reach an out-of-bounds spot the zombies cannot path to.

How to confirm the setup is working

Once you clip into a wall or terrain, watch your health bar. If it stays at full while zombies gather nearby, the position is safe and you can walk away. On the clipping maps, your character becomes inaccessible to zombies entirely, so damage stops registering.

With the auto-clicker running at 100ms, your equipped weapon keeps firing and clearing waves. Progress through waves and the boss kill confirms the loop is holding.

Common reasons the farm fails

Problem	Cause
You take damage on Abandoned Farm	Flying zombies can still hit you under the map; this spot is not fully safe.
Shelter does not clip you in	It was placed flush against the surface instead of partway inside the wall or terrain.
No Shelter available	You have fewer than the 1,000 crystals required to deploy it.
Prison Yard boost fails	The jump in and out of the Shelter was not repeated three times consecutively.
Weapon stops firing	The auto-clicker is not set to repeat until stopped, or the interval is off.

Note: map glitches and outside auto-clicker software fall outside normal play, and using them can put your Roblox account at risk of moderation. If you want to keep everything within the rules, a Bastion or Medic loadout can survive long stretches with only occasional input, and normal-input auto-shooting through the pause menu avoids third-party tools entirely.
