The Corrosion Support Gem is a Tier 1 gem that offers a unique synergy between Poison and Armour Breaking. This gem allows you to break down enemy armour while applying poison damage, making it an ideal support gem for Chaos and Physical damage builds. Whether you’re focusing on damage over time (DoT) effects or Poison-based skills, Corrosion grants you the ability to bypass enemy armour, further increasing the effectiveness of your chaos or physical damage.
When you apply Poison with a skill supported by Corrosion, the Poison damage also breaks down the enemy’s armour, reducing their defence. This effect is crucial for chaos-based or physical damage builds that rely on Poison damage or damage over time effects.
Poison and Armour Breaking Synergy: Each time Poison damage is applied to an enemy, Corrosion will break down 80% of the Poison Damage dealt as enemy armour. This makes it easier to inflict further damage on enemies with high armour, especially useful in late-game content like boss fights and high-tier maps.
Not Compatible with Armour Consumption Skills: The gem will not support skills that consume fully broken armour. This ensures you cannot use the skill to trigger mechanics that would attempt to consume the enemy’s armour after it’s broken by poison.
Poison + Armour Breaking: The combination of Poison damage and armour breaking makes Corrosion a great tool for builds that deal chaos damage or physical damage, as it applies a double effect. Not only will you poison the enemy, but you’ll also significantly reduce their defence, allowing you to deal more damage with each hit or poison tick.
80% Armour Reduction: This gem effectively breaks down 80% of the poison damage applied to the enemy’s armour. For high-armour enemies, this can be an invaluable asset, allowing your Poison or chaos-based attacks to deal more damage.
Supports Physical and Chaos Skills: Whether you are focusing on chaos damage skills (like Essence Drain or Bane) or physical damage skills (such as Heavy Strike or Cleave), Corrosion will help you maximise your damage by reducing the enemy’s armour and making it easier to deal with armour-heavy enemies.
Chaos Damage Builds: For builds focused on chaos damage or Poison (such as Essence Drain or Contagion), Corrosion helps you bypass enemy armour. It’s an excellent addition to Poison-based skill rotations, ensuring you can apply Poison damage and still get significant hits through armour.
Physical Damage Poison Builds: If your build focuses on physical damage with Poison, Corrosion provides a way to convert physical hits into Poison damage that breaks armour. This is ideal for Berserker or Champion builds that combine Poison with physical damage over time effects.
Strike and Melee Builds: For strike-based or melee poison builds, such as Dual Strike or Cyclone, Corrosion offers a synergy with Poison mechanics, allowing your strikes to not only apply damage but also break enemy armour, making your attacks more effective against tanky targets.
Boss Fight Builds: Corrosion is especially useful for boss fights where enemies tend to have high armour. The poison damage will break down their armour over time, allowing you to deal sustained damage without worrying too much about high defences.
Breaking Enemy Armour in High-Tier Content: In late-game boss fights or high-tier maps, you often encounter enemies with high armour values. Using Corrosion in these situations will help you break down their defences faster, allowing your Poison damage or chaos damage to go through without much resistance.
Synergy with Damage Over Time: Corrosion is perfect for builds that use Poison as their primary form of damage over time. Combining Corrosion with other DoT effects will amplify your overall damage as you break down the enemy’s armour, opening up their defensive weakness.
Maximize Poison Damage: By breaking enemy armour through Poison, you can boost the effectiveness of chaos damage over time. This synergy can stack with other modifiers, including Increased Damage over Time, Chaos Damage, and Poison Damage to significantly boost your overall damage output.
Stack Poison Effects: To get the most out of Corrosion, try to stack Poison damage with other Poison enhancing effects like Poison Damage over Time and Increased Chaos Damage to deal substantial damage while breaking enemy armour.
Use for Armour-Cutting in Tough Encounters: When facing bosses or elite enemies with high defences, Corrosion is a must-have to break armour and allow your Poison or chaos damage to reach its full potential.
Combine with Armour Penetration: Pair Corrosion with Armour Penetration or Penetrating Cold Resistance to further reduce the effectiveness of enemies’ armour, giving you even more damage potential.
The Corrosion Support Gem is a powerful addition to any Poison-based or chaos damage build that aims to break down enemy defences. By combining Poison damage with armour-breaking effects, this gem allows you to deal more damage to tanky enemies with high armour values, especially in boss fights and endgame content. If you’re looking for a way to amplify your Poison or chaos damage while breaking enemy armour, Corrosion is an essential gem that will boost your damage potential significantly.
Whether you’re running a summoner build, a melee strike build, or a chaos damage-over-time build, Corrosion provides a great way to maximize your damage and take down even the most resilient foes.
