Marvel Contest of Champions Act 9 Chapter 4: The Reckoning Brings the Chronoserpent Showdown
Marvel Contest of Champions launches Act 9 Chapter 4, the climactic finale to The Reckoning story arc. Players face the Chronoserpent in its ultimate form, navigate the new Scourge mechanic, and earn massive rewards including 7-Star catalysts and rank-up gems.

The final chapter of Act 9 -- The Reckoning has arrived in Marvel Contest of Champions, bringing the Chronoserpent saga to its thrilling conclusion. Chapter 4, titled "Redemption," challenges Summoners to face the parasite in its most powerful form yet.
The Chronoserpent's Last Stand
Dread Emperor Doom's link to the Chronoserpent has been severed, and hope is renewed as Carina Tivan begins to awaken from her comatose state. But that peace is short-lived -- the agents of the Chronoserpent launch a final, desperate assault. Armed with the Elder's reality and ISO-8 warping abilities, the Chronoserpent is truly the most powerful being in the Battlerealm, but that power comes at a cost. As it draws on more of Carina's strength, the power burns it from within -- a weakness Summoners must exploit.
Scourge Mechanic: The Act 9 Challenge System
Act 9 introduces the Scourge system, a set of custom quest nodes that create escalating threats. Scourge Nodes grant Defenders increasing power as they accumulate Scourge Charges, while Proliferate Nodes build those charges over time. The key to victory lies in Clarify Nodes, which allow attackers to remove Scourge Charges by performing specific actions during combat.
