Getting Started with Merges
Necromerger is a Roblox experience where you unlock characters, merge them into higher tiers, and build out your NPC army. The sibling rivalry system adds another layer on top of that, pitting your merged units against each other in automated battles. I've spent enough hours on this to know what actually works versus what you'll see on YouTube highlights. The core loop is straightforward but easy to mess up early on. You collect eggs, hatch units, merge three identical ones into the next tier, and repeat. Sibling rivalry comes in when your higher-tier units face off. The game auto-battles them based on their stats, which means your merge order matters more than most people realize. When I first started, I was just merging everything in a grid pattern without thinking about positioning. Lost a bunch of runs because my highest tier unit was sitting next to a weak one instead of flanking properly. The fix was simple: keep your strongest unit between two weaker units so it can absorb hits while the others deal damage. It sounds obvious in hindsight.
Understanding the Merge System
There are multiple tiers of units in Necromerger, starting from common NPCs and going all the way up. Each merge combines three identical units into one of the next tier. This means you need to track which units you already have before spending resources on duplicates. One thing most guides skip over is that not all units are created equal for sibling rivalry purposes. Some have passive abilities that change how they perform in battle, and these abilities don't always show up in the unit description until you actually use them. I found this out the hard way when my seemingly weak unit suddenly started healing nearby allies mid-fight. The lesson here is to test different combinations before committing to a permanent setup.
Sibling Rivalry Mechanics
Sibling rivalry pits your merged NPCs against each other in automated combat. The outcome depends on several factors beyond just tier level. Unit placement matters. Positioning your stronger units in the middle protects them while letting weaker units act as damage sponges. I learned this the hard way when I kept losing high-tier units by placing them at the edges of my formation. Passive abilities are hidden gems. Some units have abilities that trigger only under certain conditions, like when they take damage or when an ally falls. These abilities can turn a losing fight into a win if you know what to look for.

Resource management becomes critical as you progress. Each merge costs resources, and running out means you can't upgrade further. I used to hoard resources unnecessarily, which slowed my progress significantly. Now I merge regularly even when I'm not sure if I need the unit, because having a larger pool gives you more flexibility later.
Advanced Strategies
Once you get past the basics, there are some counter-intuitive moves that help. Merging lower-tier units before maxing out higher ones can actually be beneficial in some scenarios. This is because having more units on the field creates more opportunities for passive ability triggers, which can snowball into advantages. Another thing I wish someone had told me earlier: the game rewards consistency over optimization. Running the same setup repeatedly and learning its patterns beats constantly swapping units in search of the perfect composition. I spent weeks trying different combinations before realizing that sticking with one solid lineup and refining it was far more effective.
Common Pitfalls to Avoid
Don't merge units randomly. Always check what you already have before combining duplicates. This prevents wasting resources on units you don't need. Don't ignore your weakest units. They serve a purpose in sibling rivalry by drawing enemy fire and triggering abilities. Discarding them early leaves your stronger units exposed. Don't assume higher tier always means better. Some lower-tier units have passive abilities that outperform higher-tier units in specific situations. Test before you commit.
This guide won't make you invincible, but it should save you dozens of hours of trial and error. The game has enough randomness built in that no strategy guarantees wins every time. What works best varies depending on your available units and the matchups you face. Experiment with different formations and keep notes on what succeeds, then stick with those configurations. Over time you'll develop a sense for which units work well together and which to avoid.
