Contagion
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. Reanimating or detonating a corpse affected by Contagion will cause the Minion or explosion to spread Contagion on hit.
