The Coursing Current Support Gem is a Tier 2 gem that enhances Lightning-based skills by adding the ability to shock multiple enemies within a 2.5-meter radius when you shock a target with a supported skill. This gem is an excellent choice for builds that utilize Lightning damage and want to maximize their area-of-effect (AoE) damage potential by spreading the shock debuff across multiple enemies at once. The gem introduces an additional layer of crowd control and damage amplification for Shock effects.
The Coursing Current Support Gem modifies Lightning-based attack and spell skills by enabling them to spread the Shock effect to additional enemies in close proximity to the initial target. When you hit an enemy with a supported skill that applies Shock, you have a 50% chance to also apply Shock to other enemies within a 2.5-meter radius of the original target.
Shock Spread Mechanic: When you shock an enemy with a supported skill, there’s a 50% chance that any other enemies within a 2.5-meter radius will also be shocked. This creates a chain reaction of Shock effects that can dramatically increase your damage output against groups of enemies.
AoE Synergy: The ability to spread Shock to multiple enemies enhances area-of-effect (AoE) strategies, especially when using Lightning skills that already have a wide radius of effect, such as Lightning spells or Lightning projectiles. This makes Coursing Current an ideal support gem for clearing packs of enemies and dealing massive AoE damage.
Shock Spread: The main feature of Coursing Current is the ability to spread Shock to nearby enemies. When you shock an enemy, there’s a 50% chance to also shock any other enemies within a 2.5-meter radius, maximizing your damage potential.
Synergy with Lightning Skills: Coursing Current works best with Lightning-based skills, as Lightning already has a high chance to shock enemies, and this gem increases the number of targets affected. Skills like Arc, Chain Lightning, and Ball Lightning can benefit greatly from this added mechanic.
AoE Damage Amplification: By spreading the Shock effect to additional enemies, Coursing Current amplifies the overall AoE damage of your Lightning skills. This makes it especially valuable for clear speed builds, where you need to deal with multiple enemies at once.
Potential for High Damage Output: Since Shock increases the damage enemies take from your hits, having more enemies affected by Shock at the same time leads to more damage output across the board, making this gem excellent for boss fights or large-scale mob clearing.
Lightning Spell Builds: Coursing Current is perfect for Lightning spell builds, such as Elementalist or Inquisitor, where the main focus is on dealing Lightning damage to enemies. Combining this gem with spells like Arc, Chain Lightning, or Lightning Tendrils can significantly increase the number of enemies affected by Shock.
Projectile Builds: If your build relies on Lightning projectiles, this gem can boost your spread potential, especially with skills like Lightning Arrow, Ball Lightning, or Elemental Hit. Each hit has a chance to shock additional enemies, making it easier to clear out large packs of enemies.
AoE and Clear Speed Builds: For builds designed to clear mobs efficiently, Coursing Current is a great choice. It enables you to deal with multiple enemies at once by spreading Shock, making it perfect for builds that focus on Area of Effect (AoE) and clear speed, such as Storm Brand or Storm Call.
Crit and Shock Builds: If your build revolves around critical strikes that deal Lightning damage (e.g., Crit Elementalist), Coursing Current is an excellent choice to take advantage of the frequent Critical Strikes and increase the spread of Shock to nearby enemies.
Maximizing AoE Damage: To get the most out of Coursing Current, pair it with skills that already have a large area of effect. The gem’s additional shock spread mechanic makes it incredibly powerful in crowded situations where multiple enemies are grouped together, such as boss fights or crowd control encounters.
Boosting Shock Chance: Since Coursing Current relies on applying Shock to enemies, you can increase its effectiveness by stacking Shock Chance or Shock Effect through other gear, passive tree nodes, or other gem supports. Combining it with gems like Conductivity or Increased Lightning Damage will further amplify the damage potential of the shock.
Consider Radius and AoE Scaling: Since Coursing Current has a specific 2.5-meter radius, you can improve your ability to affect more enemies by investing in Area of Effect scaling through passive tree points, items, or other gems. Increased AoE will allow you to trigger Shock across a larger area, increasing the chance of spreading it to nearby enemies.
Chain Reactions in Grouped Enemies: Coursing Current becomes more effective the more enemies are nearby. By positioning yourself in areas with high enemy density (such as densely packed mobs or boss encounters with multiple minions), you maximize the chances of shocking and damaging large groups of enemies simultaneously.
Maximize Shock Chance: Since Coursing Current depends on the initial Shock from a hit, increasing your Shock chance (through passives, gear, or other support gems) will make this gem more reliable and impactful.
Pair with AoE Scaling: Since the gem spreads Shock in a 2.5-meter radius, investing in Area of Effect (AoE) modifiers will help ensure that the Shock spreads to as many enemies as possible. Combining this with AoE skills can amplify its potential.
Use in High Density Areas: To make the most of Coursing Current, focus on areas where enemies are grouped together, such as boss fights or dense mob packs. The chance to Shock multiple enemies at once increases the damage output considerably.
The Coursing Current Support Gem is a powerful tool for Lightning builds that want to increase their AoE damage and Shock spreading capabilities. By enabling Lightning skills to spread Shock to multiple enemies within a 2.5-meter radius, this gem significantly enhances damage output in crowded situations. Whether you’re looking to clear mobs or increase boss damage, Coursing Current is an excellent choice for Shock-based Lightning builds.
