The details
The Rajapendra of Mortality Raid challenges players to clear four distinct seasons of content, with the first three seasons restricting cookie placements based on elemental types.

The Rajapendra of Mortality Raid began on September 23, 2026.
The Rajapendra of Mortality Raid concludes on October 21, 2026.
Culture Shift
This update follows the established pattern of the CookieRun: Kingdom seasonal raid ecosystem. It marks a significant shift by introducing elemental placement constraints that force players to diversify their teams beyond standard meta-picks.
Players should prioritize acquiring and leveling the new Rajapendra and Mogra characters to effectively clear the seasonal raid stages. Managing the Flame of Annihilation land rule will be essential for maintaining team health during the raid window.
The takeaway
Players aiming to complete the raid should focus on mastering the Seed of Change skill to mitigate incoming debuffs. Balancing elemental requirements with character utility remains the most effective strategy for navigating the four-season event.
