Farming Rubyrubies efficiently is key to accelerating your progress in 7k Rebirth. This 7k Rebirth Ruby Farming Guide will show you step-by-step how to maximize ruby gains using “fodder” heroes, Keykey packs, and the best maps for farming. Whether you are a new player or looking to optimize your daily farming routine, this guide will help you build a steady Rubyruby income.
How Ruby Farming Works
The core principle of ruby farming is simple: each time a hero reaches level 30 for the first time, you earn 20 Rubyrubies. By repeatedly leveling low-tier “fodder” heroes, you can generate a continuous stream of rubies to invest in upgrades, summoning, or other essential resources.
Efficiency is the name of the game—this guide shows you how to farm rubies quickly with minimal investment.
1. Daily Ruby Pack – Keykey Purchase Strategy
Your ruby farming cycle begins with buying Keykeys, which allow you to progress through stages faster. There are two main Keykey purchase options:
A) Initial KeyKey Pack (Best Value)
- Cost: 50 Rubyrubies for 60 KeyKeys
- Limit: 20 purchases per day
Profitability Analysis:
| Area | Net Gain (No Booster) | Net Gain (With Booster) |
|---|---|---|
| Area 1 | -200 | -120 |
| Area 2-7 | +120 | +200 |
| Area 8-10 | +200 | +260 |
| Area 11-13 | +280 | +440 |
| Area 14-16 | +440 | +600 |
Tip: Farming becomes profitable starting from Area 2-7, even without the booster, but with the booster, your returns are significantly higher.
B) Secondary KeyKey Pack (Lower Value)
- Cost: 80 Rubyrubies for 60 KeyKeys
- Limit: 50 purchases per day
Profitability Analysis:
| Area | Net Gain (No Booster) | Net Gain (With Booster) |
|---|---|---|
| Area 1 | -2200 | -1960 |
| Area 2-7 | -1000 | -760 |
| Area 8-10 | -760 | -360 |
| Area 11-13 | -360 | +40 |
| Area 14-16 | +40 | +600 |
Use the secondary pack only after exhausting the initial Keykey packs.
2. Best Maps to Farm
Selecting the right maps is critical for maximizing your Rubyruby gain.
Milestone Maps: Focus on Map 7, Map 8, Map 11, and Map 14. These areas offer the most consistent gains and opportunities for leveling fodder heroes.
Ultimate Goal: Reach Area 14 as soon as possible for the highest profit per farming cycle.
Early Game Tip: While Area 2-1 provides the same ruby gains as Area 7-1, Area 7-1 is preferred due to a small chance of dropping a Legendary Hero Summon card.
3. Recommended Farming Heroes & Team Setup
Efficient farming relies on a hero that can clear stages quickly. Fill the rest of your team with low-level fodders to level them up.
Team Setup:
- 1x Strong Farming Hero: Handles stage clearing
- X Fodder Heroes: Fill remaining slots with heroes you want to level
Top Tier Farmers (Fastest Clearers):
- JuriJuri
- TeoTeo
- YeonheeYeonhee
- JaveJave
- MercureMercure
- NiaNia
- VelikaVelika
Good Tier Farmers (Solid Alternatives):
- RuriRuri
- Yu ShinYu Shin
- Bi DamBi Dam
- TakaTaka
- SilvestaSilvesta
- ColtColt
Pro Tip: Use your fastest farmer to maximize the number of fodders you can level per hour.
4. Understanding EXP & Fodder Leveling
Every fodder hero needs 12,500 EXP to reach level 30, which grants 20 Rubyrubies. This process, repeated across multiple heroes, is the foundation of ruby farming.
Efficiency Tips:
- Higher-level maps and special event stages provide more EXP per run.
- Focus on speed-clearing stages to level fodders rapidly.
- Using the Daily Ruby Support booster increases drops and speeds up your farming cycle.
Key Takeaways
- Level 30 Heroes = Rubyrubies: Every hero you level to 30 gives 20 Rubyrubies.
- Use a Dedicated Farmer: One strong farming hero plus fodders is the optimal setup.
- Prioritize Initial KeyKey Packs: Always buy the 50-ruby packs first.
- Climb to Area 14: This area provides the best returns and should be your main farming goal.
- Daily Boosters Help: Use the Daily Ruby Support booster if available to maximize gains.
By following this guide, you can build a consistent, profitable Rubyruby farming routine, quickly level heroes, and create a solid foundation for progressing through 7k Rebirth.
