. Success depends on maximizing your passive damage output to defeat invaders for a high score over the 3-day duration. Core Priorities Cannons are King

: Fill your board with Level 1 Cannons before merging them. They provide the most consistent damage per resource spent. Upgrade Enid's Banners

In NecroMerger , the Sibling Rivalry event is a three-day challenge where you defend an armory against invaders to earn high scores and exclusive rewards. This guide "repacks" the most effective community strategies into a streamlined, day-by-day action plan. Core Event Strategy

The event revolves around passive damage from cannons rather than active clicking. Success depends on maximizing cannon quantity and damage upgrades early to snowball your resources. sibling rivalry necromerger guide repack

Cannons are King: A single level 1 cannon generates 4,000 damage per hour. Quantity usually beats quality—do not merge cannons until your board is full.

Buffer Units: Always keep a high-health enemy (like a Warrior or Battle Mage) on the board so your cannons never stop firing while you are away.

The "Repack" Goal: Aim for 100k+ cannon damage per hour by the final day to easily clear high-score targets. Day-by-Day Progression Day 1: Setup & Resource Farming

The Sibling Rivalry event in NecroMerger is a high-stakes, three-day strategic challenge where you must maximize your score by slaying invaders in an armory run by

, the NecroMerger’s sister. To achieve a top-tier score (often targeted at 6.5M+ for free-to-play players), you must prioritize resource management and efficient damage output. Core Strategy: The Power of Cannons

In this event, Cannons are your primary tool for success. Unlike weapons that are consumed upon use, Cannons provide passive, consistent damage over time as long as there are enemies on the board.

Early Game Focus: Start by obtaining the free level 2 Cannon from the shop via an ad. Use floating weapons early on to clear low-health units like Musketeers to gain initial resources, but pivot to building as many level 1 and 2 Cannons as possible. Summary: The Sibling Rivalry is not a test

The "Spam" Rule: Do not merge Cannons early. It is mathematically better to have a board full of level 1 Cannons than a few high-level ones, as the combined damage of multiple low-level units is generally higher and covers more targets. Only merge when you literally run out of board space.

Upgrades: Prioritize Cannon Damage and Banner Spawn rates. Upgrading Enid's banners ensures a steady flow of invaders for your Cannons to shoot, preventing "wasted" damage time. Resource Management (Iron and Gunpowder)

Efficiency hinges on how you handle your two main resources: Iron (for weapons/anvils) and Gunpowder (for cannons/bombs).

Anvils: Aim for a single Level 3 Anvil. This is widely considered the "sweet spot" for generating the necessary weapons to finish off targets that your Cannons have weakened.

Furnaces: Do not merge your furnaces early. Keeping them separate provides more total Iron per hour, which is critical for maintaining your weapon supply.

The End-Game Pivot: On the final day (Day 3), once your damage per hour is high enough to kill Magicians consistently, you can stop building Cannons and start saving Gunpowder for Bombs. Bombs deal massive flat damage and are more efficient for a final "burst" to push your score into the millions in the last few hours.
