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 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

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

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.
