Shared Ability: Apocalyptic Convergence:

• Description: When all four Horsemen of the Apocalypse are present on the battlefield, they can channel their combined power to unleash a devastating cataclysmic event.
• Activation: All four Horsemen must use their action on their turn to channel their energy into the convergence.
• Effect: A dark rift tears open in the sky, unleashing torrents of chaotic energy that ravage the battlefield. All creatures within a 300-foot radius of the convergence point must make a DC 25 Dexterity saving throw, taking 100 (20d10) force damage and 100 (20d10) necrotic damage on a failed save, or half as much damage on a successful one. Structures and objects in the area are also affected, taking double damage.
• Duration: The effects of the Apocalyptic Convergence persist for 1 minute, during which time the area is engulfed in darkness and filled with swirling energy that makes movement difficult. Any creature attempting to move within the area must succeed on a DC 20 Strength saving throw or be pushed back 10 feet.
• Recharge: Once the Apocalyptic Convergence has been used, it cannot be used again until all four Horsemen have been defeated and then summoned anew through powerful rituals or divine intervention.
