When to use Rainbow vs Mono Teams
Choosing which colors to bring is one of the most important decisions in team building. Here's how the element system works and when to favor a rainbow team versus a mono-colored (stacked) one.
The Element Wheel
- There are five elements: Fire (red), Ice (blue), Nature (green), Holy (yellow), and Dark (purple).
- A strong (advantaged) hit deals double damage; a weak (disadvantaged) hit deals half damage.
- The matchups: Fire is strong vs Nature, Nature is strong vs Ice, Ice is strong vs Fire, and Holy and Dark are strong against each other.
- You can always look up element strengths in the top-left corner of the battle screen.
Key Considerations
1. Color advantage against your target — especially the tank. Double damage vs. half damage is the biggest swing in any fight, so the enemy's center hero usually dictates which color you bring.
2. Stacking boosts matched-color damage. Your tile/Troop damage is stronger with elemental advantage and increases the more heroes of that color you field.
3. A Raid subtlety: the extra Raid strong-damage bonus against the weak element decreases slightly the more same-element heroes you stack — so stacking has diminishing returns on that specific bonus.
4. Mono is counterable. Some mechanics punish teams where most heroes share one element, which matters most for defense teams.
5. Role coverage and mana reliability. A team still needs healing, cleanse, buffs, and debuffs, and you generate mana per color — both are easier to cover across five colors.
When Mono (Stacked) Is Best
Best when you know your target and want maximum burst.
- Attacking a known enemy (Raids, Alliance War): stack the color strong against their tank for double-damage tiles and faster burst.
- Titans: bring the color the Titan is weak to.
- Missions/events that reward or require a specific color.
- Trade-off: it's board-dependent — if your color doesn't appear in matches, you stall. Higher ceiling, higher risk.
When Rainbow Is Best
Best when the situation is unknown, automated, or needs reliability.
- Map/campaign progression and farming, or any fight where you don't know what's coming.
- Defense teams, where mono setups are easy to counter with a single strong color.
- Beginners or shallow rosters: more forgiving and balanced.
Rule of Thumb
- Know the target → stack the strong color (mono) for burst.
- Unknown, on auto, or building a defense → go rainbow for reliability.
Quick FAQ
Q: How much does element advantage matter?
A: A strong hit deals double damage and a weak hit deals half — it's one of the biggest factors in a fight.
Q: Is a mono team always stronger?
A: No — it's board-dependent and can be countered; rainbow is more reliable.
Q: What's best for a defense team?
A: Rainbow is generally safer, since mono defenses can be hard-countered with one strong color.
