Rune Dungeons

Runes are farmed in Rune Dungeons. There are currently 3 Rune Dungeons.

Each Rune Dungeon is further subdivided into twelve floors. The 12th floor yields the best rewards, consisting of 6★ Rare, Heroic and Legendary Runes.

# Rune Droprates

Here is a community-collected aproximation of 6★ Rune Droprates of F12.

On average, 20 rune dungeon runs will yield one Legendary Rune.

These are only approximations and might not reflect the actual rates. These also only cover F12 results, which might differ with other Rune Dungeons, however we believe they do not.

These rates were last checked on February 2022.

# Fafnir's Nest

Fafnir, also commonly known as F12, is a  guardian-type enemy. The adds are also  but Fighter-type.

Fafnir drops , , , ,  and  Runes.

## Enemies

Fafnir (Boss)

Stats: 14803 HP, 2394 ATK, 4572 DEF , 163 Speed

Fafnir's skillset
 Calling of Death (Skill3)
 Venomous Curse (Skill4)

If possible, Fafnir always performs his skills in reverse order: Skill4, Skill3, Skill2, Skill1. If the cooldown of a higher tier skill are available, Fafnir will use that skill before continuing the reverse order.

## Strategy

### First team

Starting off in F12, new players won't have the necessary Rune quality to beat Fafnir very fast. For first F12 runs to be reliable, they have to be slow.

After reading throught the Beginner Guide create your first F12 team with
Freyja as your Leader hero for her Speed  leader skill, Invincibility and Speed  from her Ghost Dancer (Skill2) and her Continuous Damage and HP Recovery from Plague Zone (Skill3)
Donovan as your main DPS for his elemental advantage and high damage
Lucifer and/or Theia as your secondary, DoT-applying heroes, since new players won't have the raw damage to deal more damage, than a Continuous Damage does.
For your first team, make sure your Donovan is at 6★. The others can work at 4★ or 5★ for now.

### Progression into faster team

Progression into faster teams comes with an increase in Rune quality. Better runes will make your first team faster naturally, but using other heroes also makes them faster.

Consider switching out heroes with
Apophis, Merlin or Apollon as your leader
Jack O'Lantern, Lucifer, Oliver or any other debuff-scaling DPS to take advantage of easily appliable debuffs
Titanos, Nocturne, Mary or any other hero with AoE skills to clear the first wave faster
### Speed team

With the correct heroes and Rune quality, Speed teams can reach down to run times of below 10 seconds.

This team is fast and reliable, while allowing for Rune-leeway due to the Action Gauge increases of Nocturne and Lilith. This also means that even at low Speed, your heroes will move twice before the boss does, securing a win.
Furthermore, Jack O' Lantern covers the inconsistency of placement. Since she has a range of 4, she will always be in range to attack Fafnir.

# Sealed Armory

Aggelos' skillset
 Energy Charge (Skill2)

## Strategy
