THE 10TH ANGEL (EOB) GUIDE

OVERVIEW

Echoes of Battlefield is a time limited Guild-Event that allows players and their guilds to test their coordination, patience, and mechanics. This special round of Echoes of Battlefield is a EVA-themed boss that features ‘The 10th Angel’ wreaking havoc with it’s AT Fields and Sector-Wide attacks, leaving parties tumbling and dodging for their lives.
Players in this gamemode are able to freely pick and swap their class of choice at any point within the event. This event features Fixed Level Characters, meaning all Players and Classes sport the same stats while in the event stage. This lets players experience other classes and allows for more in-depth strategizing.
The event also features a new system that we will coin “Bonus Buffs” that allows players to gain extra effects/modify their skills to their advantage.
All in all, these changes allow a fair competitive environment while expanding it strategically.
In this quick guide we'll be breaking down the obtainable rewards, Optimal Class Compositions, Builds, Bonus Buffs, and the boss' mechanics.

LEADERBOARD & REWARD

There is a great bounty and glory for those who want to compete in this game mode. There are the rewards which come from clearing for the first time, and Glory for those wanting to chase the Leaderboards.
Completing this event for the first time awards the player with 500 Stellarite, 10 CC4 Skill Summons, 3 Melomon Summon Selection, 3000 Basic Resonance Stone, and 1000 Ringed Leaf.
During the first and subsequent clears, The player is eligible to be put into two Leaderboards. The Guild Leaderboard, and the Adventurers Leaderboard. Both of these leaderboards are cross-server, based within the same region.

Guild Leaderboard

First and foremost, players are only eligible to rank within the Guild Leaderboard when all participating party members belong to the same Guild. Only the fastest clear time is registered within the Guild Leaderboard, representing their Guild.
Guilds ranging in the top 1-200 are rewarded with cosmetic rewards. These cosmetics have small distinctions based on the specific ranking of the party. These changes appear in brackets listed below.

Rank	Reward
1-10	Guild Banner (Peerless Climber) Chat Frame (Roar of Lions)
11-50	Guild Banner (Pierce the Firmament Chat Frame (Tide of Rage)
51-100	Guild Banner (Tempest of Blades) Chat Frame (Bloodbound Glory)
101-200	Guild Banner (Valor's Anthem)
2 Parties Cleared Challenge in Guild	Guild Banner (Iron Heart)

Adventurers Leaderboard

Within the Individual Leaderboards, all parties participating are entered and recorded based on their fastest clears when running with any team. This leaderboard does not provide any ranked rewards, though acts as a record for those who have cleared it before.
This leaderboard also provides some rewards to the whole regional server based on how many unique parties have cleared the Echoes of Battlefield. Rewards are unlocked at 1, 5, and 10 unique party clears.

1	100 Stellarite 100 Runes 10000 Gold
5	300 Stellarite 20 Recharge Crystals 50000 Gold

Optimal Ringed Leaf Usage

We recommend players to spring for the Melomon Small Puzzle Box Selectors as they are quite limited in availability and the other items in the shop are common rewards within other systems / events.
Players can opt to go for the Benevolent Beast Point Cards if they do not need the extra melomon shards, as is the case for some spenders.
The Fluttering Leaf Items are too overpriced compared to their value. Players may find some use out of Inspiration and Basic Resonance Stones only if they have a massive surplus of Fluttering Leaves.
If the player does not have much excess leaves, do not touch this portion of the store.

CLASS COMPOSITION & BUILDS

General Information

Before Heading into battle, having a proper team composition and the right skills equipped is paramount when trying to clear this content. All characters and classes in this gamemode are CC3 Level 135, although stats reflect the characters being around CC0. They also have a predetermined Pet / Melomon. Players are able to adjust their Tactical Skills and Passives to maximize their damage.
In terms of Team Compositions, we recommend running with 1 Healer, 1 Tank, and 2 of any DPS. This boss requires Healers for their use of Purification to cleanse the DoT and Divine Healing to survive boss's wipes, while the tank's purpose is to absorb the bosses' high single target damage without getting one shot.
All players come pre-equipped with Turning Point allowing for some mistakes while learning the mechanics.

Team Composition

A Standard Composition for this fight would be 1 / 2 / 1, or 1 Tank, 2 DPS, and 1 Healer.
This composition allows the players to safely engage with the 10th Angel and can easily draw its attacks to the places where the party wants them to be, due to the tank’s taunt mechanics.
A Speedrun Composition will comprise of 0 / 3 / 1, or no Tank, 3 DPS, and Healer.
This composition will deal much more damage when compared to the above but will require tighter mechanics due to not having a dedicated tank, needing to make sure the healer has Divine Barrier to block the Tank Busting Attack.

Bonus Buffs

Every Class Type (Tank, Healer, and DPS) can equip 1 of 3 special buffs that can modify skills to provide extra effects, or provide buffs when certain conditions are met. These bonus skills will aid greatly with clearing, making runs much faster / safer when utilized properly.
Below is a list of Bonus Skills each Class Type can equip.

This effect can only be triggered once per instance of Self-Discipline, and when activated, reduces the DMG dealt of the ally affected by this skill by 40%, persistent until the end of Self-Discipline.

Vengeful Wrath	Every 10 seconds, increase all DMG dealt by 2% and DMG taken by 5%. Up to 10 stacks

Class Build

With all of these factors at play, below are builds that fulfill the required mechanics while maximizing damage. Keep in mind that only one DPS will need to carry interrupt so be sure to coordinate within the party.

Tank

Healer

Healer (Hybrid)

Swordbearer (DPS)

Wayfarer

Scholar

Shadowlash

Acolyte (DPS)

Role Summary

Below are the recommended Skill for the roles :

Role	Mandatory Skill	Bonus Buff
Tank	Stalwart Shield, Taunt	Tactic Shift (Buff 2)
DPS	-	Vengeful Wrath (Buff 3)
Healer	Purification, Restoration	Tactic Shift (Buff 2) )

In terms of DPS Compositions, Eagle Eye and Nightweaver reign supreme as the top choice for the highest output out of the 5 classes. Swordmaster is overshadowed by the other two options, and Archmage does not have the correct passive equipped for dealing damage, making her obsolete. Thaumaturge has fairly high DPS but is a lower priority when compared to the aforementioned classes.

THE 10TH ANGEL (BREAKDOWN)

Molten Seal Dragon only have one phase, the players will have to familiarize themselves with to triumph against this boss. These movesets are explained in the order that the player will encounter them, leading to a smoother learning experience.

General Information

The Mechanics within this fight are quite simple. The fight takes part within a circular arena, where the players can move around and dodge the bosses’ attacks.
The 10th Angel’s Attacks are all Sector-Based, meaning all if not most of them can be dodged by moving.
The goal within this fight is to dodge and move together with the team to avoid overlapping attacks over multiple sectors.
Players will want to move in groups of four, to bait Reject-Type Offense, making the boss use Circular Destruction less.
TL;DR Pick a direction to move and move as a team of four.
For a more in-depth breakdown, check out the boss breakdown below.

Reject-Type Offense

The 10th Angel will form an AT Field in Sectors with more than 2 players, isolating damage. Players in this Sector will have their attacks weakened by 100%. Afterward, the angel will cause the field to crush forward, dealing massive damage to all targets in that sector.
Players should stay in groups of 4 and avoid the move so that damage is not reduced by 100%, to prevent the boss using harder move such as Circular Destruction.

Terror Pressure

A terrifying aura from another world causes nearby targets to suffer continuous internal bleeding; all players lose 5% of the max HP per seconds, stackable and can be cleansed.
Healers will need to bring purification to cleanse this ongoing effect.

Laser Blast

Casts Laser Explosion on the current target, dealing massive damage.
Tanks will need to use Stalwart Shield during this effect to reduce incoming damage. Teams with no tanks will need to bring a healer with Radiant Barrier to block the one shot.

Circular Destruction

The 10th Angel spins to attack surrounding sectors, dealing massive damage to affected targets.
Stay in the safe spot, and move together towards a certain direction indicated around the boss.

Rending Shock

Locks onto a random direction and begins charging, then unleashes a shockwave that deals massive damage to all targets within that sector, and applies 10 stacks of bleed. Bleed deals massive damage over time and can be cleansed.
This attack is randomly deployed in one direction and should be dodged easily.

Homing Crush

During Recitation, randomly locks onto 1 to 2 players. When Recitation ends, forms an AT Field above their current position, then rapidly crushes onto the ground, dealing Lethal damage to targets in the sector. IF a locked player moves any 1 random step, they will be tracked again, and a new AT Field will form above the new position for a second crush. Sectors crushed by an AT Field leave behind a shockwave that continues to deal damage for 9s.
Players should position themselves together in one sector, and move together to avoid spreading too much DoT behind (at most 2 if done correctly).

Core Weakness

When HP drops to %, the 10th Angel becomes disabled and its Core can be attacked. If the core is broken, the body will be knocked back. IF the core is not broken, the body will recover 10% hp within 15s. The core can only be attacked from the sector directly in front of it.
Players should position themselves in front of the core right before the boss’ HP drops below to 1% to instantly knock it out.
