As players transition from the turn-based combat of Honkai: Star Rail to the urban open-world of Hethereau, identifying the core progression loops is essential for character power. Understanding how to farm gear efficiently in the new environment requires a clear look at the systems that replace familiar mechanics like the Cavern of Corrosion.

# HSR 4.3 Cavern of Corrosion Explained: Farming Gear in Neverness to Everness

The Neverness to Everness (NTE) equivalent to the Honkai: Star Rail (HSR) Cavern of Corrosion is the [Rabbit Hole](https://www.ldshop.gg/news/neverness-to-everness-guide-123) domain, which is the primary source for [Cartridges](https://www.topuplive.com/blog/nte-gear-system-explained). While HSR players farm Relics, NTE players utilize the [Console System](https://nte.perfectworld.com/), which combines these Cartridges with Tetris-like [Modules](https://www.topuplive.com/blog/nte-gear-system-explained) obtained through the [Rewind System](https://www.ldshop.gg/news/neverness-to-everness-guide-123) using [Carrota Coins](https://www.topuplive.com/blog/nte-gear-system-explained).

## Question Restated

When looking for the HSR 4.3 Cavern of Corrosion equivalent in Neverness to Everness, several key questions arise regarding the transition between these two systems. Players often want to know exactly where the gear farming domains are located within the sprawling city of Hethereau and how the stamina costs compare to the Trailblaze Power they are used to spending.

The core of the inquiry focuses on:
*   What is the specific equivalent of the Honkai: Star Rail 4.3 Cavern of Corrosion in Neverness to Everness?
*   How do players farm endgame gear, specifically the Cartridges and Modules that make up the Console System?
*   Where can players find these domains in the Hethereau districts?
*   What are the specific costs in terms of Character Pixels and what reward tiers can be expected at different levels?

In Honkai: Star Rail, the Cavern of Corrosion provides Relics with fixed slots (Head, Hands, Body, Feet). In NTE, the system is more fluid, requiring players to manage both the base gear and the spatial arrangement of sub-components. This guide breaks down these differences to ensure your Espers are ready for high-level content.

## Direct Answer

In Neverness to Everness, the gear system is known as the [Console System](https://nte.perfectworld.com/), which uses [Cartridges](https://www.topuplive.com/blog/nte-gear-system-explained) and [Modules](https://www.topuplive.com/blog/nte-gear-system-explained) instead of traditional Relics. The direct equivalent to the Cavern of Corrosion is the [Rabbit Hole](https://www.ldshop.gg/news/neverness-to-everness-guide-123) domain. This domain is physically located in the [Cape Square](https://nte.perfectworld.com/) district of Hethereau, often found near the New Herland border.

Farming a single run of the [Rabbit Hole](https://www.ldshop.gg/news/neverness-to-everness-guide-123) costs [40 Character Pixels](https://www.topuplive.com/blog/nte-gear-system-explained), which is the NTE version of Trailblaze Power. While the [Cartridges](https://www.topuplive.com/blog/nte-gear-system-explained) themselves drop directly from these domain clears, the [Modules](https://www.topuplive.com/blog/nte-gear-system-explained)—the sub-components that provide additional stats—are primarily obtained via the [Rewind System](https://www.ldshop.gg/news/neverness-to-everness-guide-123). This system uses [Carrota Coins](https://www.topuplive.com/blog/nte-gear-system-explained) earned as a secondary reward from your [Rabbit Hole](https://www.ldshop.gg/news/neverness-to-everness-guide-123) clears.

| **World Currency** | Credits | [Fons](https://nte.perfectworld.com/) |

## Detailed Explanation

The transition from HSR to NTE involves moving away from linear gear slots into a more spatial, puzzle-oriented system. Understanding the relationship between the domain, the stamina, and the resulting gear is vital for optimizing characters like [Nanally](https://nte.perfectworld.com/) or [Haniel](https://nte.perfectworld.com/).

### The Console System: NTE's Unique Gear Mechanic

The [Console System](https://nte.perfectworld.com/) is the heart of character progression in Neverness to Everness. Unlike the six slots in HSR (four Relics and two Ornaments), NTE uses a grid-based interface. Each Esper has a unique Console layout, which functions like a Tetris board. 

Players must first equip a [Cartridge](https://www.topuplive.com/blog/nte-gear-system-explained). This [Cartridge](https://www.topuplive.com/blog/nte-gear-system-explained) determines the base stats and the available grid space for that character. Once the [Cartridge](https://www.topuplive.com/blog/nte-gear-system-explained) is active, players insert [Modules](https://www.topuplive.com/blog/nte-gear-system-explained) into the grid. These [Modules](https://www.topuplive.com/blog/nte-gear-system-explained) come in various geometric shapes (L-blocks, squares, long bars) and provide the bulk of the character's sub-stats, such as [Cycle Rate](https://www.topuplive.com/blog/nte-gear-system-explained) and [Break DMG](https://www.topuplive.com/blog/nte-gear-system-explained). The challenge lies in fitting the highest-quality [Modules](https://www.topuplive.com/blog/nte-gear-system-explained) into the limited space provided by the [Cartridge](https://www.topuplive.com/blog/nte-gear-system-explained).

### Farming Cartridges: Accessing the Rabbit Hole

To obtain these [Cartridges](https://www.topuplive.com/blog/nte-gear-system-explained), you must head to [Cape Square](https://nte.perfectworld.com/). The [Rabbit Hole](https://www.ldshop.gg/news/neverness-to-everness-guide-123) is an instanced domain that features various combat challenges against urban anomalies. 

The rewards from the [Rabbit Hole](https://www.ldshop.gg/news/neverness-to-everness-guide-123) scale based on your [Appraisal Level](https://www.ldshop.gg/news/neverness-to-everness-guide-123). As you complete [Appraisal quests](https://www.ldshop.gg/news/neverness-to-everness-guide-123) (also known as Anomalous Realm challenges), you unlock higher difficulty tiers.

**Rabbit Hole Reward Tiers by Appraisal Level**

| Appraisal Level | Difficulty Tier | Primary Rewards (Cartridge Rarity) |
| :--- | :--- | :--- |
| 1-10 | Tier 1 | Blue (Rare) |
| 11-20 | Tier 2 | Blue (Rare), Purple (Epic) |
| 21-30 | Tier 3 | Purple (Epic) |
| 31-40 | Tier 4 | Purple (Epic), Gold (Legendary) |
| 41+ | Tier 5 | Guaranteed Gold (Legendary) |

Reaching the higher tiers is the equivalent of farming Difficulty VI in HSR's Caverns. It is generally recommended to save your [Character Pixel](https://www.topuplive.com/blog/nte-gear-system-explained) refills until you have reached the [Appraisal Level](https://www.ldshop.gg/news/neverness-to-everness-guide-123) required for Gold drops.

### Farming Modules: Carrota Coins and the Rewind System

While the [Rabbit Hole](https://www.ldshop.gg/news/neverness-to-everness-guide-123) drops [Cartridges](https://www.topuplive.com/blog/nte-gear-system-explained), it does not directly drop the [Modules](https://www.topuplive.com/blog/nte-gear-system-explained) needed to fill them. Instead, each run rewards you with [Carrota Coins](https://www.topuplive.com/blog/nte-gear-system-explained). These coins are the currency for the [Rewind System](https://www.ldshop.gg/news/neverness-to-everness-guide-123), which is essentially a targeted gacha for gear parts.

There are three types of [Carrota Coins](https://www.topuplive.com/blog/nte-gear-system-explained):
1.  **Bronze Carrota Coins**: Used for basic [Module](https://www.topuplive.com/blog/nte-gear-system-explained) pulls, typically resulting in Blue or Purple rarity pieces.
2.  **Silver Carrota Coins**: Used for intermediate pulls with a higher chance for Gold [Modules](https://www.topuplive.com/blog/nte-gear-system-explained).
3.  **Gold Carrota Coins**: Used for high-end "Rewinding," allowing players to target specific shapes (like a 2x2 square) or specific stats (like [Cycle Rate](https://www.topuplive.com/blog/nte-gear-system-explained)).

This system offers more control than HSR's Relic farming. If you have a [Cartridge](https://www.topuplive.com/blog/nte-gear-system-explained) with a specific empty spot, you can use your [Gold Carrota Coins](https://www.topuplive.com/blog/nte-gear-system-explained) to try and "Rewind" a [Module](https://www.topuplive.com/blog/nte-gear-system-explained) that fits that exact geometry.

### Optimizing Your Build: Set Bonuses and Grid Placement

Activating set bonuses in NTE requires matching the [Cartridge](https://www.topuplive.com/blog/nte-gear-system-explained) type with the character's [Esper](https://nte.perfectworld.com/) element or role. For example, an [Incantation](https://nte.perfectworld.com/) focused character like [Nanally](https://nte.perfectworld.com/) benefits from [Cartridges](https://www.topuplive.com/blog/nte-gear-system-explained) that boost elemental damage or [Cycle Rate](https://www.topuplive.com/blog/nte-gear-system-explained).

The stats available on these items are divided into primary and secondary categories:

**Primary Stats (Cartridges)**
*   Attack (Flat or %)
*   HP (Flat or %)
*   Defense (Flat or %)
*   [Cycle Intensity](https://www.topuplive.com/blog/nte-gear-system-explained)
*   [Break Intensity](https://www.topuplive.com/blog/nte-gear-system-explained)

**Sub-Stats (Modules)**
*   [Cycle Rate](https://www.topuplive.com/blog/nte-gear-system-explained)
*   [Break DMG](https://www.topuplive.com/blog/nte-gear-system-explained)
*   Critical Rate / Critical DMG
*   Elemental DMG (Lakshana, Cosmos, Anima, Incantation, Chaos, Psyche)

Managing your [Character Pixels](https://www.topuplive.com/blog/nte-gear-system-explained) is crucial. They regenerate at a rate of [1 point every 6 minutes](https://www.topuplive.com/blog/nte-gear-system-explained), with a maximum cap of 240. This means you get 240 pixels per 24 hours, enough for six [Rabbit Hole](https://www.ldshop.gg/news/neverness-to-everness-guide-123) runs. Early on, it is often better to spend these on Hunter's Manuals for character leveling rather than gear domains.

Beyond the basic gear farm, the effectiveness of your [Console System](https://nte.perfectworld.com/) setup is heavily influenced by how it interacts with the broader game mechanics of Neverness to Everness.

### Esper Elements and Reaction Synergy

The stats you farm in the [Rabbit Hole](https://www.ldshop.gg/news/neverness-to-everness-guide-123) must align with the [six Esper elements](https://nte.perfectworld.com/): [Lakshana](https://nte.perfectworld.com/), [Cosmos](https://nte.perfectworld.com/), [Anima](https://nte.perfectworld.com/), [Incantation](https://nte.perfectworld.com/), [Chaos](https://nte.perfectworld.com/), and [Psyche](https://nte.perfectworld.com/). 

High [Cycle Rate](https://www.topuplive.com/blog/nte-gear-system-explained) on your [Modules](https://www.topuplive.com/blog/nte-gear-system-explained) allows for faster elemental applications, leading to powerful reactions. For instance, combining [Incantation](https://nte.perfectworld.com/) and [Anima](https://nte.perfectworld.com/) can trigger the [Blossom](https://www.ldshop.gg/news/neverness-to-everness-guide-123) effect, while other combinations lead to [Hexed](https://www.ldshop.gg/news/neverness-to-everness-guide-123) states on enemies. Your gear choices directly dictate how often these high-damage windows occur.

### Progression Gates: Hunter and Appraisal Levels

Your ability to access the highest tiers of gear is gated by two separate leveling systems. Your [Hunter Level](https://www.ldshop.gg/news/neverness-to-everness-guide-123) represents your overall account progress and is increased by completing story missions and daily activities. 

However, the [Appraisal Level](https://www.ldshop.gg/news/neverness-to-everness-guide-123) is what specifically unlocks the higher difficulty levels of the [Rabbit Hole](https://www.ldshop.gg/news/neverness-to-everness-guide-123). To raise this, you must complete periodic [Appraisal quests](https://www.ldshop.gg/news/neverness-to-everness-guide-123). These are combat trials that test if your current team composition and gear are sufficient for the next tier of world difficulty.

### Urban Life: The Tycoon Management System

Farming gear is only one part of the NTE experience. As you stabilize your combat power, you will earn [Fons](https://nte.perfectworld.com/), the primary urban currency. This currency is used in the [Tycoon System](https://nte.perfectworld.com/), allowing you to buy property, customize businesses, and purchase vehicles. 

While [Character Pixels](https://www.topuplive.com/blog/nte-gear-system-explained) are for combat growth, your [Fons](https://nte.perfectworld.com/) are for urban growth. Efficiently clearing domains like the [Rabbit Hole](https://www.ldshop.gg/news/neverness-to-everness-guide-123) ensures you can tackle harder missions that reward larger amounts of [Fons](https://nte.perfectworld.com/), creating a loop between your combat prowess and your status in Hethereau.

## Frequently Asked Questions

### What is the best way to spend Character Pixels early in NTE?
Early in the game, it is most efficient to spend [Character Pixels](https://www.topuplive.com/blog/nte-gear-system-explained) on character and [ARC weapon](https://nte.perfectworld.com/) ascension materials. Since high-rarity [Cartridges](https://www.topuplive.com/blog/nte-gear-system-explained) only drop at higher [Appraisal Levels](https://www.ldshop.gg/news/neverness-to-everness-guide-123), farming the [Rabbit Hole](https://www.ldshop.gg/news/neverness-to-everness-guide-123) before level 30 often yields gear that will be replaced quickly.

### How do I get more Carrota Coins for the Rewind System?
[Carrota Coins](https://www.topuplive.com/blog/nte-gear-system-explained) are primarily earned by completing [Rabbit Hole](https://www.ldshop.gg/news/neverness-to-everness-guide-123) domain runs. You can also obtain them through certain urban side-quests in [Hethereau](https://nte.perfectworld.com/) or as rewards for increasing your [Hunter Level](https://www.ldshop.gg/news/neverness-to-everness-guide-123).

### Can I change the shape of a Module I already own?
You cannot directly change the shape of an existing [Module](https://www.topuplive.com/blog/nte-gear-system-explained). However, using the [Rewind System](https://www.ldshop.gg/news/neverness-to-everness-guide-123) with [Gold Carrota Coins](https://www.topuplive.com/blog/nte-gear-system-explained) allows you to pull for new [Modules](https://www.topuplive.com/blog/nte-gear-system-explained) while selecting a preferred shape category to better fit your [Console](https://nte.perfectworld.com/) grid.

### Where is the Cape Square district located?
[Cape Square](https://nte.perfectworld.com/) is located in the southern portion of the [Hethereau](https://nte.perfectworld.com/) map, adjacent to the [New Herland](https://nte.perfectworld.com/) business district. It serves as a major hub for high-end shopping and contains the entrance to the [Rabbit Hole](https://www.ldshop.gg/news/neverness-to-everness-guide-123) gear domain.
