Eikthyrnir Guide

Published: March 1 2022

Last Updated: December 17 2023

This guide covers the recommended team compositions and strategies to beat Eikthyrnir. The goal is to maximize the acquisition of River Source, a rare material exclusively acquired from the First Time Stage Clear rewards and World Tree Tower Exchange Shop.

Demonic Beast Battles are the main source of Holy Relic materials. When crafted, it grants registered heroes special effects and additional basic stats. It is the most difficult PVE content to clear, requiring your heroes to be maxed out in levels and equipment to compete. Specific skills are also needed to counter the gimmicks in each Phase. Damage Reduction and Strong single-target burst damage are important characteristics of your team.

There are currently three floors, each with 4 phases to clear. First-Time Stage Clear Rewards can be claimed after clearing a floor once before resetting. Simultaneously, stage rewards can be farmed repeatedly to acquire other materials.

## Recommended Teams

* We will update the guide accordingly as the game progresses and more heroes are released

### Teams Without Jormungand

**Note:**

* You will need one hero of each main three attributes (**Speed**, **Attack,** and **HP**) on the team as the boss has a rotation sequence that requires a hero with a certain attribute to attack in order (See below) and later phases will have a damage reduction grey buff that will cap its damage and require a rotation making it impossible to use a with two or more Light and/or Darkness (ex. Light Elizabeth and Light Mael) to avoid dealing with the rotation sequence.

## Roles

**Damage Dealer** - Heroes with high single-target damage that can cut through the boss’ high defense.

**Support/Utility** - Heroes who can greatly reduce damage from the boss, while being able to power up and boost the team. Surviving for a few turns will help you collect all the necessary cards before moving on to the next phase.

**Taunt** - Redirects all single-target attacks to the hero with higher defense capability.

## General Strategy

The big key about Green World Serpent Jormungand is her passive throughout the fight; you must use only three cards to maintain Green World Serpent Jormungand's passive uptime because you will remove her passive on that one unit if you use one, two, or four cards on one turn. Green World Serpent Jormungand’s passive will only stack up twice every phase, each stack providing a 30% increase to all stats.

### Preparation

#### Equipment

Dark Traitor Meliodas - Attack / Crit Dmg (Red Escanor Association)

Red Halloween Matrona - HP / Defense (Blue Giant Diane Association)

Blue "The One" Escanor - Attack / Crit Dmg (Red Demon Meliodas Association)

Green New King Arthur - HP / Defense (Blue Tarmiel Association)

Green Brunhild - Attack / Crit Dmg (Red Sariel Association)

Green Jormungand - HP / Defense (Fighter Diane Association)

Red Skadi - HP / Defense (Blue Tarmiel Association)

Red Freyr - Attack / Defense (Blue Tarmiel Association)

Blue Festival Cusack - Attack / Crit Dmg (Red Demon Meliodas Association)

Blue Festival Berserk Estarossa - Attack / Crit Dmg (Red Sariel Association)

#### Useful Artifacts Sets

**No.2 Guardian of Istal**

* If an ally is Debuffed from a skill during the enemy's turn, restores 1 / 2 / 3 / 4 / 5% of their Max HP. (Excludes PVP and Death Match)

**No.3 Adventures in Midgard**

* Increases allies' damage dealt with single-target attack skills by 2 / 4 / 6% (Excludes PVP and Death Match)

**No.13 What's the Tally?**

* Recovers 1 / 1.5 / 2% of Max HP at the start of the allies' turn when taking damage. (Excludes PVP and Death Match)

Since Eikthyrnir is a fierce demon with high attack and defense, Recovery/Taunt and Damage Reduction are necessary skill effects to bring in battle. Red Halloween Matrona can recover allies every turn while receiving damage, while Green New King Arthur can reduce incoming damage with his Unique ability.

### Floor 1

#### Phases 1 and 3

These two phases should be used to prepare and collect the necessary cards needed for Phases 2 and 4.

What you need to prepare are Attack and Ultimate cards from the 3 Attributes (Strength, HP, and Speed)

With Jormungand’s Unique Ability, your team will deal increased damage and take much less in return. Also, if you happen to have her Holy Relic, each phase will go by much quicker since  she will rank up all of your skills if you attack three times (once with three different characters). Regardless, there are no specific gimmicks here, just deal your damage and move on.

#### Phase 2 and 4

In these phases, you will have to follow the attribute wheel in order to deal more significant damage. You can start with any color so long as it follows the next color properly. Since this is only Floor 1, the boss is not very tanky, so it should be simple enough to beat it. Just note that in Phase 4, the boss has increased health so feel free to save Ultimate Moves to clear it quicker.A

Attack order is important on Phases 2 and 4; the sequence of attack must be in Strength → HP → Speed, HP-> Speed-> Strength or Speed-> Strength-> HP. Attacking continuously with the same attribute will penalize your team and will disable your attacks, the same thing goes for attacking the boss with a Light and/or Darkness attribute as it will register as attacking with the wrong attribute unless you attack with those units first on your turn. You can track which attribute is needed by looking at the color indicator above the boss. You can follow the attack sequence by looking at the “attribute display” on the upper right of your screen. By keeping the order of attacks, attack-increasing buffs are applied to allies which makes it easier to defeat the boss.

In Phase 2, it is best to defeat the boss with skill attacks.

In Phase 4, it is recommended to use the special moves of each attribute in order.

Eikthyrnir will be able to get a counter stance move. **Do not attack when Eikthyrnir uses its stance ability, It** **counterattacks with a fatal damage returning 1500% of its Attack**. It is best to skip the next 2 turns, sustain when necessary, and wait for the stance buff to end before attacking again before it gets renewed unless your team got barriers as the counter will automatically miss with heros with barriers which allows you to attack without being wiped out. **The Stance is immune to Stance Cancel effects.**

### Floors 2 & 3

Floor 2 basically  has the same strategy as Floor 1 except that the 2nd phase has a new gimmick. Your hero gets frozen if it does not follow the attack sequence. However, Eikthyrnir inflicts fatal damage on his special attack if there is no frozen character on the field. **You would need to get your character frozen during turn 2 to avoid getting team wiped.** However it can be avoided if you can manage to take out the boss before turn 2.

#### Phase 1 and 3

Similar to Floor 1, Phase 1 and 3 are preparation phases. It should be used to collect the necessary cards needed for Phases 2 and 4 (Same for all floors).

Blue “The One” Escanor, Blue Milim, or Blue Festival Cusack will be the main attacker for Speed-type heroes. Green World Serpent Jormungand replaces the role of Green Arthur if obtained and provides 60% defensive stats stacking with Dark Traitor Meliodas. Red Skadi is a perfect choice because she has two attack cards, which makes the color-match requirement less painful. Red Freyr as well will act as a double red attack skill user and provide a 15% to all basic stats to the team.

#### Phases 2 and 4

**You need to get your character frozen before the boss uses its special attack.**

In Floor 2 Phase 2, the boss will have damage reduction until you complete one rotation of the attribute wheel which can make it impossible to clear the phase by finishing it with a Light and/or Dark attribute units. As such, you should use weaker cards in the first turn and preserve your better cards for afterwards. Conversely, in Phase 4 of Floor 3, the same damage reduction will be in place. **Do not attack when Eikthyrnir uses its stance ability**, it has a damage suppression buff and **counterattacks with a fatal damage returning 1500% of its Attack**. It is best to skip the turn, sustain when necessary, and wait for the stance buff to end before attacking again unless you got a hero with barriers as the counter will automatically miss with hereos with barriers which allows you to attack without being wiped out and will remove the Stance with one rotation. **The Stance is immune to Stance Cancel effects.**

Eikthymir will add an unremovable corrosion debuff at Floor 3 if you do not follow the correct color order. However, the corrosion debuff will not stack and it is manageable if you have Jormungand buffing your Lifesteal stat. Furthermore, Eikthymir adds an Ignite debuff at Phase 4, 3 turns in when it uses it's stance if you get the Grounded Attitude passive which can pose a issue to your units if you choice to wait out it’s stance as it will deal more damage to your units though it can be avoided if you have a cleanse unit or a unit with Ignite Immunity such as Green Valentines Melascula and Red Freyr

It is important to note that the boss will heal all its HP with an increase to its basic stats if the boss falls below 20% during the final phase of Floor 3. It is recommended that you attempt to kill the boss before the stance can be used unless you got a hero with barriers. In all honesty, while it isn't impossible to beat the stage after the Stance is used, it is such a pain and hard to beat that you might as well reset the stage unless you got a hero with barriers as the counter will automatically miss with heroes with barriers which allows you to attack without being wiped out.

One neat trick you can use if you accidentally make the boss fall below the 20% threshold is you can close the game and log back in to reset the turn. Also, if you happen to use a unit with a Death Ultimate, you can actually use it during turn 1 if you have a second card for that unit. For example, if you want to use Blue "The One" Escanor's Ultimate Move, use one of his normal skills, followed by the respective attributes, and then in the fourth attack slot, use his Ultimate to get significant damage on the boss. This is pictured above.

Another neat trick is you can actually remove the stance by completing one rotation of the color order but however either you need a hero with barriers as the counter will miss with heroes that have barriers or 3 Heroes that are Speed, Attack and HP attributes that have their ult moves ready as counters doesn't get triggered by Ult moves though the latter will be more difficult to pull off due to the boss frequently using deplete ultimate move. The former strategy shown below shows heroes with barriers casted by Green Valentines Melascula completes one color rotation sequence and the one after shows it gone after completing one rotation.
