## What is T-Creds Protocol Space?

T-Creds Protocol Space is a **special combat challenge mode** located in Valley Pass and Valley IV that rewards T-Credits, the primary currency in Arknights: Endfield. It features a poisonous mist mechanic that challenges players with continuous HP damage.

### T-Credits

Primary currency for shop purchases, pulls, upgrades

### Range

Stage 1: 8,500 to Stage 5: 34,000 T-Creds per run

### Poison Mechanic

Continuous poison damage - kill enemies to heal

### Critical: Healer Mandatory

The poisonous mist deals continuous damage to all operators. A strong healer is absolutely required - even the best DPS operators will die without proper healing sustain through the mist.

## Complete Stage Overview

| Stage | Name                | Sanity | T-Creds |
| ----- | ------------------- | ------ | ------- |
| 1     | Blessing of Tin     | 40     | 8,500   |
| 2     | Blessing of Ferrium | 50     | 13,500  |
| 3     | Blessing of Cuprium | 60     | 19,500  |
| 4     | Blessing of Argenta | 70     | 27,500  |
| 5     | Blessing of Oros    | 80     | 34,000  |

### Note: T-Creds Rewards

T-Creds scales linearly with Sanity cost: \~213 T-Creds per Sanity. Higher stages offer better density but require stronger teams to handle increased poison damage.

## Mechanics Breakdown - Poisonous Mist

**Mechanic:** Poisonous mist surrounds the arena causing all operators to continuously lose HP. Defeating enemies restores some HP.

### What This Means

* • All operators slowly take damage from poison mist over time
* • Cannot simply wait out enemies - poison damage accumulates
* • Must defeat enemies quickly to restore HP and offset poison
* • DPS and sustain both essential

### How to Counter

* • Build team with high DPS to clear enemies fast
* • Bring healer to sustain against poison damage
* • Focus fire on one enemy at a time for quick HP restoration
* • Use skills that deal burst damage for faster clears
* • Consider operators with poison resistance (if available)

### Pro Tip: Poison Mist Survival

The poison mist rewards fast clears and strong healing. Build a team with dual DPS and a skilled healer. Taking down enemies quickly restores HP and offsets the continuous poison damage.

## Stage-by-Stage Walkthroughs

### Stage 1: Blessing of Tin (40 Sanity) - Easy

**T-Creds:** 8,500 | Unlocks immediately upon discovering protocol space

Basic enemies, 2-3 waves. Poison damage low.

**Strategy:** Balanced team 2 DPS + 1 Healer + 1 Tank. Fast clears and healer mandatory. Focus fire on one enemy at a time.

Pro Tip:

Excellent Sanity efficiency. Run 2-3 times daily for consistent currency income. Poison damage manageable with strong healer.

### Stage 2: Blessing of Ferrium (50 Sanity) - Easy-Medium

**T-Creds:** 13,500 | Same enemies as Stage 1 with more HP

**Strategy:** Use Stage 1 team if clears are fast. Healer still essential. Good T-Creds per Sanity ratio.

**When to Move:** When Stage 1 clears are under 2 minutes and healer sustain is comfortable.

### Stage 3: Blessing of Cuprium (60 Sanity) - Medium

**T-Creds:** 19,500 | Moderate HP enemies, 3 waves. Poison damage moderate

**Strategy:** Increase DPS for faster clears. Strong healer required. Focus fire on priority targets. Sustain is key.

### Stage 4: Blessing of Argenta (70 Sanity) - Hard

**T-Creds:** 27,500 | High HP enemies, 3-4 waves. Poison damage significant

**Recommended:** Operators Level 40+, E1 promoted team

**Strategy:** Strong team required. Dual-DPS and excellent healer mandatory. Focus fire for HP restoration.

### Stage 5: Blessing of Oros (80 Sanity) - Very Hard

**T-Creds:** 34,000 | Very high HP enemies, 4-5 waves. Poison damage severe

**Recommended:** Operators Level 60+, E2-E3 promoted team

**Strategy:** Endgame content. Maximize DPS, best healer mandatory. Coordinate team, focus fire. Highest efficiency stage.

## Team Composition Guide

| Slot | Role     | Recommended                           | Priority |
| ---- | -------- | ------------------------------------- | -------- |
| 1    | Main DPS | Physical/Heat operators with high DPS | High     |
| 2    | Sub DPS  | Complementary element operator        | High     |
| 3    | Support  | Healer (strong sustain mandatory)     | High     |
| 4    | Tank     | High DEF/HP operator                  | Medium   |

### Critical: Healer Mandatory

The poisonous mist deals continuous damage. A strong healer is absolutely required. Even with perfect DPS, operators will eventually die without healing. Never attempt T-Creds Protocol without a healer.

## When to Farm T-Creds

| Authority Level | Recommended Stage | Runs Per Day |
| --------------- | ----------------- | ------------ |
| 25-30           | Stage 1-2         | 2-3          |
| 30-40           | Stage 2-3         | 2-2          |
| 40-50           | Stage 3-4         | 1-2          |
| 50+             | Stage 4-5         | 1-2          |

## Common Mistakes & How to Avoid Them

### 1\. Running Stage 5 too early

Problem: Attempting Blessing of Oros at Authority 25-30\. **Fix: Progress naturally. Stay on Stage 1-2 until operators Level 30-40\. Stage 5 requires E2-E3 team.**

### 2\. Forgetting healer

Problem: Bringing DPS-heavy team without healer and dying to poison. **Fix: Healer is mandatory in T-Creds Protocol. Bring strong healer or die to mist.**

### 3\. Not killing fast enough

Problem: Slow DPS taking too much poison damage. **Fix: Dual-DPS team for fast clears. Focus fire on one enemy at a time to restore HP.**

### 4\. Spreading damage across enemies

Problem: Attacking multiple enemies simultaneously. **Fix: Focus fire on one enemy at a time. Killing enemy restores HP - spreading damage prolongs poison exposure.**
