In the NecroMerger event Sibling Rivalry, success revolves around maximizing Cannons to deal constant passive damage over three days. Core Strategy: The "Cannon Barrage"
Prioritize Cannons: Build as many Level 1 Cannons as possible rather than merging them into higher levels. Multiple lower-level cannons provide more total damage per hour.
