Ruby Farming Guide - Best Character for Nightmare Farming

This is a Ruby Farming guide for Seven Knights Re:BIRTH (7K Rebirth). Read on to learn about Ruby Farming's benefits, how to level and power up heroes, as well as tips and tricks!

Early Game Guide

What is Ruby Farming?

Basic Farming Method

Ruby Farming is the term used for Repeat Battles or Auto Battles, which involves repeatedly challenging and completing a designated stage in order to level up heroes, farm Gold, acquire hero materials, and farm the premium currency, Rubies.

Best Repeat Battle Settings

We recommend adjusting the Auto Replace Hero settings and turning off the settings for 1★s, while leaving 2-6★ turned on. This is because 1★ heroes tend to clutter your inventory at higher levels and should largely be used as emergency materials for when you are farming Story Events, which have no hero drops.

Tip!	Move 1★ heroes into your Storage to free up Inventory space as you continue Ruby Farming!

Benefits of Ruby Farming

Focus on Other Resources, Not Rubies

Since we will be re-investing our Rubies into purchasing Keys, despite being called Ruby Farming, the main objective is to collect Keys, currency, and material resources for enhancing your existing Heroes, and less about gathering Rubies for the Gacha.

How to Spend Rubies

Rubies : Keys : Farming Ratio
50 Rubies Spent	1 Key Bundle	60 Keys	10 Normal Runs 5 Nightmare Runs
250 Rubies Spent	5 Key Bundles	300 Keys	50 Normal Runs 25 Nightmare Runs

By spending 250 Rubies on Key Bundles in the Shop, you can earn approximately 300 Rubies after 50 Repeat Battles when farming Region 11-1. Essentially, this nets you a profit 50 Rubies in addition to Gold, fodder heroes, and other drops. You could even spend the 50 Rubies on another Key Bundle, which grants you 60 Keys to spend in other content like Raids.

Tip!	If you're strong enough to farm Region 14-1, you can get even more Rubies (up to 400) per 50 runs. So try to progress your Adventure towards that Region.

Slight Ruby Profit from Other Content

Since Keys allow the player to access a variety of other content, such as Raids, Story Events, and Adventure, as well as raising our Adventurer Skills, it is more efficient to use the Rubies earned from Ruby Farming on Keys from the Shop. Especially since completing other content offers Ruby rewards in addition to other benefits.

Legendary Heroes Can Drop

On very rare occasions, Legendary Heroes can drop during Repeat Battles. Above, we were able to obtain a 4★ Silvesta during our Ruby Farming!

Best Heroes for Ruby Farming

Nightmare Ruby Farming

Most Recommended arKyle, , Teo, Klahan, Yeonhee

Kyle	- AoE Attacker with high burst and sustained damage - His passive ability targets the strongest enemy making him highly effective in taking down key enemies - Can deal additional damage thanks to his passive ability
Teo	- Has Powerful AOE Skills - Doesn't need to Transcend, but it is recommended for Nightmare Stage 6-1 onwards
Klahan	- Strengthen Physical Attack, Crit Rate & DMG - Doesn't need to Transcend, but it is recommended for Nightmare Stage 6-1 onwards
Yeonhee	- Transcending will not increase stability, so Teo and Klahan are more recommended

Rin is a Powerful but Situational

Rin	- Has Good health and Attack, but both her skills target 4 enemies, making her situational

Other Options

Jave	- Lacks stability as it requires Burn and Counterattack - Works if you can defeat most enemies with Skill 2 and then use Skill 1
Velika	- Make sure to strengthen Crit rate & dmg - Make sure to use Skill 2→1 in order
Juri	- Works Attack specialized build - Enhancing Passive Skill to increase Immortality duration from 2 to 3 turns
Silvesta	- It is useful if it has enough attack to reduce the enemy's HP with Skill 2 and defeat with Skill 1
Fai	- If Skill 2 was able to spread damage to other enemies, Fai can work, but it is unstable

Ideally, for Ruby efficiency, 1 damage dealer + 4 heroes for leveling up is recommended, but if it is unstable, having 2 damage dealers or 1 damage + buffer/debuffer is an option. This will reduce Ruby's efficiency, but it is recommended to prioritize stability, so decide if you want stability for farming accessories or more Leveling Up slots for Ruby.

Example Build & Stats for Nightmare Difficulty

Teo	Klahan

Above is an example of Teo and Klahan's build we used to complete Nightmare difficulty, where it has a 100% completion rate at Stage 1-1 and 98% at 6-1 as a single Damage dealer. Klahan has an 83% Crit Rate, so use the pet to make it to 100% for more stability. In the case of stage 6-1, Klahan cannot complete just by using both skills, so use Normal Attack to finish off.

Normal Ruby Farming

Heroes with AOE Damage Skills are Suitable

For the Normal Stage, most Heroes with 1 or 2 skills that can target All Enemies are suitable. Check the skills of the Heroes you own and find which is most suited when Ruby Farming.

Rei is Recommended for Beginners

On top of above mentioned characters, recommend Ruby Farming Heroes for the Normal stage is Rei. For beginner players, Rei is a perfect starter for Ruby farming in early games, as both her skills target all enemies. Additionally, she can be obtained early in the game, so enhance and gear her up to start Ruby Farming from the early game.

Rei - Rating & Skills

Pull Welcome Rate Up Summon for Teo

For 14 days after the account is created, a special banner, "Welcome Rate Up Summon", featuring Teo, will be available. Teo is one of the best Ruby Farming heroes, even for Nightmare Difficulty, so make sure to pull and secure Teo.

How to Level Up Heroes Fast

Tips for Fast Leveling

To efficiently level up heroes, we recommend repeating steps 1-4 above. If needed (❗), consider using the subscription-based support content and pets that increase Adventure efficiency.

1. Progress Adventure

The first and most important tip is to progress as far as you can in the Adventure mode. You can get Rubies and Hero Summon Vouchers from Star Rewards, and all regions past Traitor's Labyrinth (Region 7) grant increasingly more EXP, which increases the efficiency of Ruby Farming.

Tip!	All stages within the same region grant the same amount of EXP. Additionally, you get the same amount of EXP from Region 2 to Region 7.

2. Buy Keys, Gold, or Summons with Rubies

Ruby Farming Cycle

By raising hero levels to 30 through repeat battles, then getting Rubies from missions, and finally buying Keys, you can earn more Rubies by repeating steps 1-3. This entire process is called Ruby farming, and using this method to get Rubies for buying Gold or for Summons is the key to efficient leveling.

How to Start Repeat Battles

Stage 1 of each area is most suited for repeat battles, so set up your formation and repeat battle settings there. We recommend using a Defence formation, placing your strongest AoE-focused hero in the back row, and setting 4 heroes to be swapped in the front row.

Tip!	You can create a party for Repeat Battles in the "Ruby Farming Team" tab in upper left section of the Team creation team.

You Can Multitask

Repeat battles will continue even if you close the app or play other content like the Power Up Dungeons, Arena, or Tower of Abyss. During Story Events, you can run them alongside Adventure, allowing for even more efficient Ruby farming.

3. Max Level All Heroes and Pets

Once you obtain Rare or Legendary heroes and pets through Summons, etc., it's time to level them up. The specific leveling methods and flow are described later.

▼Jump to How to Power Up Heroes

4. Play Other Content

Content Details and Rewards

Once your heroes are sufficiently leveled, take on battle content like the Power Up Dungeons, Arena, the Tower of Abyss, and Raids. You can obtain various leveling materials, Rubies, Hero Summon Vouchers, equipment, and more, allowing for further account progress.

5. Avoid Exceeding Key Capacity

Duration	Approx. 10:00min	Approx. 60:00min
Repeat Battles	50 Repeat Battles	300 Repeat Battles
Keys Charged (Uncapped)	5 Keys (No sub) 10 Keys (Daily Power-Up Support)	30 Keys (No sub) 60 Keys (Daily Power-Up Support)
Keys Charged (Capped)	0	0

Keys regenerate at the rate of 1 Key per 2 minutes, and 50 Repeat Battles takes approximately 10 minutes to complete. This means that if your keys aren't exceeding your current key cap., you could be regenerating 5 Keys during your Repeat Battle, whereas being capped charges no additional keys.

6. Utilize Adventure Effects

Blessing of Gold	Gain 10% more Gold from Adventure
Adventure's Fortune	Equipment and accessory drop rate from adventure increased by 10%
Encounters in Adventure	Hero drop rate from adventure increased by 10%

New players receive free Adventure Effects in the form of new player buffs. These buffs grant a bonus 10% to Gold, Equipment, Accessory, and EXP drop rates in Adventure Stages for 2 weeks. So be sure to make full use of these Adventure Effects while they last.

Adventure Effects are Available for Purchase

Once the free Adventure Effects expire, players can reactivate the same bonuses by purchasing the Daily Ruby Support from the Shop. These grant the same 10% drop rate bonuses while additionally granting 200 Rubies per day for 28 days

Optional: Pay for Subscriptions

If you want to level up even more efficiently, consider purchasing the subscription-based support content from the Shop. The Daily Ruby Support, which gives you a total of 5,600 Rubies for logging in daily, is especially recommended.

Optional: Obtain Specific Pets

List of Recommended Adventure Pets
Pet	4-Star Skill Effect	Recommendation
Doo	Increases equipment drop rate in Adventure by 5%	★★・・・
Mimic	Gain 5% additional Gold in Adventure	★★★★・
Eri	Increases hero drop rate in Adventure by 5%	★★★★★
Mole	Increases equipment drop rate in Adventure by 10%	★★★・・
Mick	Gain 10% additional Gold in Adventure	★★★★★

Including the pets above in your Adventure Team will make leveling and farming more efficient. If you get them from Summons or Fusion, be sure to add them to your Adventure party. If you don't already have them, you can also get them through Pet Crafting.

Tips!	Trading for a Rare pet requires 4 ★4 pets, and trading for a Legendary pet requires 8 ★6 Rare pets, so the material requirements are quite high. Crafting itself is unlocked after clearing Adventure 2-5.

How to Power Up Heroes

Hero Power Up Process

1. Complete Adventure to Level Up

Complete Adventure stages using the Repeat Battle function to raise your heroes' levels to 30.

2. Enhance to +5

Use fodder heroes as materials to Enhance selected heroes to +5. You'll often get low rank heroes suitable as materials from the Ruby Farming process.

Note!	Power Up is unlocked after clearing Adventure 1-6.

Enhance Guide

3. Collect Particles

Use Pooki Tokens to collect Particles (Rank Up Materials) in the Power Up Dungeon. Similar to Keys (stamina), Pooki Tokens will automatically recover over time, but the recharge time is long, so be sure to avoid capping on Pooki Tokens.

4. Rank Up

Once you have gathered the required Particles, Rank Up your hero. Since Rank Ups provide a significant boost in stats, always aim to get your best heroes to 6-stars.

Note!	The Rank Up feature unlocks after clearing Adventure 1-20.

How to Rank Up & Get Materials

5. Repeat Steps 2-4

Repeat steps 2-4 to Rank Up your Rare and Legendary heroes to 6-Stars. Once you reach 6★ (+5), the basic strengthening is complete. The following steps are for min-maxing your Heroes, which are still essential steps if you want to clear all of the available content.

6. Transcend Duplicate Heroes

Transcending enhances stats or skills at specific transcendences levels. You can do this up to 12 times, and the number of materials required increases as the Transcendence level goes up, meaning you will need multiple duplicates to reach the maximum transcendence level.

Tip!	Transcendence is unlocked after clearing Adventure 2-20, and you can do it at any time after that. If you get a duplicate hero, it's recommended to level it to Lv. 30 through Ruby farming before using it for Transcendence.

Transcendence Guide

7. Enhance Skills

Obtain Skill Enhancement Stones from Events, the Arena, Guild War, etc., and use them to enhance the skills of your 6-Star heroes. Skill Enhancement Stones are somewhat harder to come by than other materials, so think carefully about which hero to use them on.

Tip!	Skill Enhancement is unlocked when you obtain a 6-Star hero.

How To Enhance Skills

8. Undergo Ultimate Enhancement

Once you have numerous, unneeded 6★ Heroes, or have Leah, you can expand a Hero's equipment slots by undergoing Ultimate Enhancement. While it's possible to use 6-Star heroes as materials, it's generally recommended to use the Ultimate Enhancement Material, Leah.

Tip!	Ultimate Enhancement is unlocked once you obtain a 6-Star hero.

Ultimate Enhancement Guide

How to Farm Fodder/Enhancement Materials

Utilize Repeat Battles

When you complete Adventure stages, heroes may drop. Typically, these dropped heroes range from 1-Star to 3-Star heroes, which we recommend using as Hero Enhancement materials.

Tip!	Make sure to level up these low rank heroes to 30 before using them as fodder to maximize your Ruby profits!

Use Hero Tickets

If you have Common or Uncommon Hero Tickets in your Inventory, consume them to receive fodder. Hero Tickets are fairly easy to come by, and can be obtained from the Shop, Events, the Tower of Abyss, and more.

Perform Hero Summons

Using 1-Star to 3-Star heroes from Summons as Power Up materials is another viable option. Note that this requires Hero Summon Vouchers or Rubies, making it difficult to recommend as a primary method, however, it is still an option.
