Contagion is a Tier 1 Chaos spell in Path of Exile 2 that applies a spreading damage-over-time debuff. When an enemy dies while affected, Contagion and all other Chaos DoT effects spread to nearby enemies and refresh their durations. This makes it a powerful tool for clearing packs and scaling damage through propagation.
"Afflict a single enemy with a Debuff that deals Chaos damage over time. If the enemy dies while affected by Contagion, it and all other Chaos damage over time Debuffs spread to nearby enemies and refresh their durations."
Note: Purchasing this item, you will receive a level 21 Contagion gem with 5 Support Sockets.

Path of Exile 2 Contagion Mechanics FAQs
Does Contagion's spread include other Chaos DoTs like Essence Drain or Wither?
Yes. When an enemy dies while affected by Contagion, it spreads all Chaos damage-over-time effects on that target—including Essence Drain, Wither, and Chaotic Freeze—to nearby enemies and refreshes their durations.
How does Contagion's damage scale with spread count?
Contagion's own DoT gains +100% more damage each time it spreads, up to a maximum of +300%. This bonus applies multiplicatively to its base damage and does not affect other Chaos DoTs that are spread alongside it.
Can Contagion be propagated through corpse interactions, such as Detonate Dead or Raise Zombie?
Yes. Reanimating or detonating a corpse affected by Contagion will trigger a spread event. However, this does not count toward the +100% damage stacking—only death-based spreads increase Contagion's damage.
Does Spell Damage affect Contagion's DoT?
Yes. Modifiers to Spell Damage directly apply to Contagion's damage-over-time effect, making it viable in hybrid builds that scale both spell and chaos damage.
Can Contagion be supported by Unleash, Spell Echo, or Multicast?
Yes, but with caveats. Contagion does not stack multiple independent debuffs—recasting simply overwrites the previous effect. Unleash and Spell Echo are best used for multi-target coverage, not for stacking damage.
