War Inc: Rising offers a deep squad-building system that goes far beyond simple rarity tiers. While most players initially assume that stacking mythic or legendary heroes will guarantee victory, the game’s mechanics prioritize something else entirely — merge level.
This War Inc Rising Best Team Building Guide breaks down how team power actually works, how to merge troops correctly, and how to build the strongest possible lineup for both PvE and infinite modes.
1. Team Power and Merge Levels
At first glance, War Inc: Rising’s unit system looks like a standard hero collector. You summon troops of different rarities — Common, Rare, Epic, Legendary, and Mythic — and deploy them into your lineup. However, rarity isn’t the main factor behind power.
Instead, the most significant stat in determining overall combat strength is the merge level of each unit.
- Merge Level = The number of times a troop has been combined with duplicates.
- Higher merge levels multiply base stats far more than rarity increases alone.
- A merged Rare unit can outperform an unmerged Mythic unit in most cases.
When you view your troop list, you’ll notice a small merge icon at the bottom-left — that’s where all the hidden potential lies.
2. How to Merge Units the Right Way
The game doesn’t make this part clear. Here’s how to ensure you’re getting maximum power from your roster:
Open your Barracks.
You’ll see every troop you own, including new summons.
Tap the Merge Icon.
It looks like three small squares connected by lines. This menu shows all available combinations.
Remove All Units from Your Lineup.
Troops currently assigned to your team cannot be merged. You must manually unequip each one before combining.
Use the “Combine All” Option.
Confirm the merge to fuse every available duplicate automatically.
Once done, you’ll notice your troops’ merge levels increase — some by one or even multiple stars — significantly boosting their combat rating.
3. The Wrong Way: Building by Rarity
A common mistake players make is filling their lineup exclusively with their highest-rarity troops. While it looks impressive, this approach is extremely inefficient early on.
For example:
- A team built by rarity alone may reach around 9,000 battle power.
- That same team, rebuilt using merge level priority, can exceed 19,000 battle power with the same mana cost.
Rarity contributes to stat growth, but merge level determines how much of those stats actually activate in battle. Therefore, your top priority should always be to merge duplicates before chasing new mythics.
4. The Correct Way: Building by Merge Level
The winning formula for raw power is simple:
Prioritize units with the highest merge level that fit within your 100 mana limit.
Each troop consumes a certain amount of mana to deploy. Since you only have 100 to spend, your goal is to fill that budget with the strongest, most upgraded combinations — not just the rarest cards.
Example Power Results (from testing):
| Team-Building Method | Approx. Power |
|---|---|
| Rarity-Only (All Mythic) | ~9,000 |
| Merge-Level Focused | ~19,700 |
| Power-Level Sorted | ~18,600 |
| Hybrid (Mythic + Merge) | ~19,400 |
As shown, merge-based setups outperform every other configuration. Even a team with mixed rarities but high merge consistency can dominate.
5. Hybrid Team Method (Optional)
If you have a few well-upgraded Mythics, you can mix them into your merge-based lineup for added bonuses. A practical hybrid setup involves:
- 2 merged Mythics (for passive or skill utility)
- 3–4 heavily merged Epics or Legendaries
- Staying under the 100 mana limit
This method performs nearly as well as full merge-level setups, especially for modes that reward skill synergy or elemental balance.
6. Managing Mana Efficiently
Your total mana pool (100) restricts how many units can be deployed simultaneously. Since stronger units require more mana, balance is key.
Don’t simply field as many troops as possible — focus on the highest stat-per-mana ratio units.
Tips:
- Avoid filling your team with expensive unmerged Mythics — they eat mana without offering proportional power.
- Mix a few lower-cost merged units to maximize total stats per mana spent.
- Rebuild your lineup whenever you finish merging to ensure no merged units are sitting idle.
7. Why Merge Level Matters More Than Rarity
In nearly every mode except Co-op, merge level dictates your overall effectiveness. This is because:
- Merging scales attack, health, and ability potency linearly.
- Rarity only affects base stats and sometimes skill uniqueness.
- Merged lower-rarity units outperform unmerged high-rarity ones in total contribution.
In Co-op, synergy and skills become slightly more important — so mixing rarities can be justified there — but for solo progression, merges dominate.
8. Recommended Progression Routine
To build the strongest team quickly:
- Summon troops regularly. Even duplicates are valuable.
- Remove your lineup completely before merging.
- Combine All to upgrade everything possible.
- Rebuild using merge level sort.
- Check your power rating — it should nearly double compared to rarity-based setups.
- Repeat after each batch of summons.
Also, don’t neglect coin-based troop recruitment (the original recruitment tab). Even though it seems outdated once you unlock gem summons, it still feeds valuable materials and duplicates into your merge system.
