This page is about the projectile behavior. For the support gem, see Chain Support.

Chain is a behavior of projectiles and chaining skills that causes them to bounce off targets they hit seeking out other nearby targets.

Mechanics

Only one projectile behavior can be applied each time a projectile hits a target. Chain has third priority for projectile behaviors, preceded by pierce and fork, and followed by return.

When a projectile chains, it bounces off the target it hits and continues in the direction of another nearby target. A chaining skill like ArcArcSpell, Chaining, Lightning

Each time the main beam chains it will also chain to a second enemy, but that secondary arc cannot chain further.Per 1% Quality:1Superior2Anomalous3Divergent4Phantasmalchain 1 times1% increased Chaining range0.5% increased Damage for each time this Skill has Chained1% reduced Enemy Stun ThresholdDeals (6-133) to (33-754) Lightning Damage

A projectile or chaining skill can chain between multiple targets repeatedly, but it can never hit the same target twice in a row. A projectile or chaining skill will not chain if there is no other target close enough to the one hit.

Each projectile or chaining skill can chain a certain number of times. The number of times a projectile or chaining skill can chain is equal to the sum of all Skills Chain +x times modifiers and other similarly-worded modifiers.

Projectiles apply their on-hit effects to each target they chain on or otherwise hit. For example, Essence DrainEssence DrainSpell, Projectile, Duration, Chaos, AoE
