Sibling Rivalry Necromerger Guide Repack (2026)

Sibling Rivalry

The event in NecroMerger is a three-day challenge unlocked at Devourer Level 32 where you defend an armory against your sister Enid's invaders. The primary strategy for high scores is maximizing Cannon damage early while transitioning to Bombs for high-health mages in the final hours. Core Gameplay Mechanics

• Do not save mana. Spend every drop.
• Immediately summon your cheapest unit to start the mana generation cycle (units returning mana on death/merge).
• If you have the Chef (or equivalent mana generator unit), prioritize spawning them first to boost your economy.

1. Holding Lv1 Shields: They clog your board. Feed them to the Devourer (in event) for 1 energy. Yes, you can delete them.
2. Ignoring the Hourly Chest: The free chest every 4 hours contains 5-10 gunpowder. That is 2 cannon shots. Never miss it.
3. Merging Banners early: Wait until you have 4 Lv1 Banners. Merge to 1 Lv3 Banner. Claim for 50 crowns instead of 3 separate claims for 15 total.

Bombs

Switch to for late-stage damage. Use the Alchemy Table to convert excess Gunpowder into massive bursts. 💡 Quick Tips for High Scores sibling rivalry necromerger guide repack
