A Fatal Floors thorns hallway is an environmental hazard corridor filled with green, damaging thorn bushes that restrict player movement and drain health over time. Stepping into this hallway variant triggers the official Roblox badge "That Stings." Surviving and navigating these overgrown corridors requires understanding their damage properties, spawn differences across updates, and tool interactions.

Thorns Hazard Overview

In FaultyMarkus Games' Roblox survival title Fatal Floors, Thorns serve as an obstacle that fully infests designated hallways, vents, and door frames. While they do not actively hunt the player like mobile entities, their environmental placement can trap explorers in dead ends or leave them vulnerable during chases.

Unlike lethal drop pits, touching thorns does not cause instant death. However, because the damage ticks continuously as long as you make contact, sprinting through a dense corridor without high-tier class health upgrades can quickly deplete your health bar.

Spawn Floors and Update Changes

Documented sources show a distinct difference in where thorns appear depending on the game build:

  • Post-Hazards Update: According to community documentation on the Hazards Update, Thorns officially spawn from Floor 15 and onwards. The update also formally reclassified Thorns from an entity to an environmental hazard.
  • Earlier Builds (Kiwi Update Era): Footage from player runs documented thorns spawning as early as Floor 2. Video patch impressions from that update noted that thorns spread faster across hallway floors while individual tick damage had been reduced.
  • Previous Glitches: In older builds, thorn growth could clip through walls, spread out of bounds, and even push past closed elevator gates.

If you encounter thorns early in a run, you may be playing on an older branch, whereas current wiki documentation marks Floor 15 as the standard threshold.

How to Clear Thorns Using the Hammer

You do not have to endure continuous damage when exploring a blocked path. The Hammer—a 2-star utility item purchasable in the elevator for 15 coins—can actively dismantle thorn bushes.

  1. Equip the Hammer: Purchase the black-and-blue hammer tool from the elevator item offerings when available.
  2. Target the Bush: Look directly at an overgrown thorn bush and click on it while holding the hammer.
  3. Select Delete Tile: A prompt appears on the left side of your user interface showing "Move tile" and a red button labeled "Delete tile."
  4. Remove the Obstacle: Click "Delete tile" to eradicate the bush entirely, clearing the walking lane.

Community testing notes that while some bushes may regrow over time, deleting the clusters near doors and narrow corridors creates a permanent or semi-permanent safe path for hauling ore back to the elevator. Additionally, because the hammer currently features an unrestricted target range, players can clear bushes from a safe distance before entering the hallway.

Survival Strategies and Entity Interactions

Navigating a thorns hallway requires careful attention to your surroundings and current health reserves.

Entity Evasion in Thorns

  • Cave Crawler Staredowns: Player guides report that you can crouch or hide inside a thorn bush to break line of sight from a Cave Crawler. While the thorns will slowly chip your health, this tactic can buy time because the Cave Crawler requires an uninterrupted 3-second staredown before initiating an aggressive chase.
  • Door Closures: Running from entities like the Weatherman through a thorns hallway is dangerous due to the severe speed reduction and diminished jump height. Always close facility doors or mansion gates behind you to stall pursuers while wading through foliage.
  • Keep the Elevator Clear: Never drag entities or allow overgrown growth into the elevator, as restricted mobility inside a tight space will lead to a team wipe.

Health Management

Because low-tier bandages do not exist and restorative items like campfires (which cost 75 coins to purchase and use for cooking eggs), water fountains, and carrots are typically found on deeper floors, unnecessary thorn damage adds up fast. Avoid entering dead-end thorn branches unless ore trackers confirm valuable minerals like Jade, Amber, or Amethyst are waiting at the end.

Frequently Asked Questions

How do I get the "That Stings" badge in Fatal Floors?

The "That Stings" badge is unlocked automatically upon entering a generated Thorns Hallway during a floor exploration run.

Can thorns kill you immediately?

No. Thorns deal low, repeated damage ticks rather than instant-kill damage. However, remaining stuck in dense patches will rapidly drain your life bar, especially if your character has not increased base health through higher classes.

Do thorn bushes regrow after being deleted?

According to wiki documentation, players using the Hammer's "Delete tile" feature can remove the bushes, but some thorn bushes may slowly regrow over time.

Can entities walk through thorns?

Yes. Entities can navigate hallway environments, and thorns do not prevent dangerous monsters like the Weatherman, Cave Crawler, or Bone Hound from reaching you if they have detected your presence.
