Arknights Endfield: Perfect Analysis & Utilization Strategy for the Core Debuff 'Corrosion'In Arknights Endfield, 'Corrosion' is a unique and crucial debuff that lowers enemy resistance. Since it doesn't stack with other buffs/debuffs, its effective damage increase is very high, especially potent against high-resistance enemies. Learn more about Corrosion's stage-by-stage effects, optimal application time for maximum efficiency, and the damage increase calculation based on enemy resistance.
1. 🎮 Importance and Basic Understanding of the Corrosion Debuff
· Corrosion is a crucial debuff that lowers enemy resistance, and its low chance of stacking with other buffs/debuffs makes it very important.
· Corrosion has an effect similar to Pericana Antal's Shock, but it is a special debuff that can achieve even greater effects depending on how it's used.
· Like other elemental debuffs, it is divided into 4 stages, with the effect amount varying by stage.
· Corrosion has an effect similar to Pericana Antal's Shock, but it is a special debuff that can achieve even greater effects depending on how it's used.
· Like other elemental debuffs, it is divided into 4 stages, with the effect amount varying by stage.

2. 📊 Stage-by-Stage Effects of Corrosion and Debuff Application Method
· Corrosion gradually reduces all of the enemy's resistances, requiring a certain amount of time to reach its maximum effect.
· Corrosion is not 'increased damage taken by the enemy' but 'reduced enemy resistance,' making it a valuable debuff that does not stack with most character skills.
· It has an effect similar to Levatein's first talent (20 Resistance Ignore).
· Corrosion is not 'increased damage taken by the enemy' but 'reduced enemy resistance,' making it a valuable debuff that does not stack with most character skills.
· It has an effect similar to Levatein's first talent (20 Resistance Ignore).
| Corrosion Stage | Resistance Reduction (Max) |
|---|---|
| Stage 1 | 12% |
| Stage 2 | 16% |
| Stage 3 | 20% |
| Stage 4 | 24% |

3. ⏳ Gradual Application Time and Maximum Efficiency of Corrosion Effect
· The Corrosion debuff takes 10 seconds after application to reach its maximum effect.
· For example, Alderia's initial Corrosion duration is 7 seconds, so to see its full effect, you need to increase the duration through breakthroughs.
· Therefore, when building a Corrosion combo, it is crucial to apply Corrosion as quickly as possible.

| Corrosion Stage | Initial Debuff | Per-second Increase | Time to Max Effect |
|---|---|---|---|
| Stage 1 | 3.6% | 0.84% | 10s |
| Stage 3 | 6% | 1.4% | 10s |

4. 🎯 Maximizing Corrosion Efficiency Based on Enemy Resistance
· The effect amount of Corrosion refers to 'resistance reduction,' and the higher the enemy's resistance, the greater the damage increase from Corrosion.
· For enemies with no resistance, damage increases by the amount of Corrosion's resistance reduction (e.g., 12%), but for enemies with high resistance, you can see a damage increase effect beyond that.
· Damage Calculation Formula: Calculated as (Damage ratio based on enemy resistance + Resistance reduction from Corrosion × 0.01).
· Example:
· When applying Corrosion Stage 1 (12% reduction) to an enemy with 100 Resistance: Damage increases by 1.12x.
· When applying Corrosion Stage 1 (12% reduction) to an enemy with 50 Resistance: Original 0.5x damage → (0.5 + 0.12) = 0.62x damage. That is, 0.62 / 0.5 = 1.24x (24%) damage increase.
· Therefore, actively utilizing Corrosion against high-resistance enemies is very effective.

5. 💡 Corrosion Utilization Summary and Future Outlook
· Corrosion gradually reduces enemy resistance values stage by stage, and it takes 10 seconds to reach maximum effect, so caution is needed when constructing combos.
· Resistance reduction can be considered a separate damage increase effect that does not stack with other debuffs, making it very efficient.
· The higher the enemy's resistance value, the greater the damage increase effect from Corrosion, making it an essential debuff for high-resistance enemies.
· You can check the enemy's resistance grade (e.g., D-grade) in the game, and the importance of Corrosion is expected to grow even further when high-resistance enemies of A or S grade appear in the future.
