Revision as of 16:56, 16 October 2023

This guide provides tips and strategies for the thirteenth strike mission and how to defeat Dagda in the Cosmic Observatory. If your group is struggling, the guidelines in the Introduction to Raiding will apply here as well. Check out the glossary page if you're not familiar with a term used in this guide and make sure to run an optimal build from our list of recommended builds for this encounter.

Introduction

Though the barrier, Dagda awaits. She is a relatively simple boss with only a few key mechanics, but punishment for repeated failure is quite high.


Dagda will only ever move as part of mechanics, and many of her attacks only hit players in melee range. A group that is really struggling to survive could stack a short distance away from the boss and range her, but this is quite an extreme approach.


Note that while Dagda becomes untargetable during split phases, she never becomes invulnerable, which means that condis will continue to do damage and may be more optimal here as they allow new phases to start at lower health.


Unlike most raid and strike encounters, this fight does not have a boon rip at the start, nor will it refill class-specific resources such as Life Force.


Strategy

The fight starts as soon as someone attacks Dagda. Dagda will target the closest entity (including pets etc.) with her auto chain, so players taking a lot of damage can back away slightly to gain a respite.


Dagda's basic attack chain is Strike Vengeful Strike Starburst. The final attack of this chain fires a cosmic projectile that can be blocked, or reflected for a bit of damage.


Shooting Stars

Every 1-3 auto chains, Dagda targets a random player with a large green arrow that will deal 90% of that player's max health as damage after seven seconds. The targeted player receives a target symbol above their head and an on-screen message: "Beware the Shooting Stars. Hide behind your allies!"

If at least five players stand between Dagda and the targeted player, then each of them will instead take 10% of their max health, while the target takes 20%. Otherwise, every player other than the target will take 50% of their max health as damage and receive a stack of Infirmity Infirmity for 30 seconds, reducing incoming healing by 25% per stack.

The targeted player should take a few steps back (at least to max melee range) and remain stationary, while every other player should stand in front of them.


Spinning Nebula

Every so often, rather than , Dagda will spin in place, firing out multiple projectiles in all directions and pulsing heavy damage in the area around her. The projectiles can be blocked or reflected, though they deal no damage to Dagda when reflected.

If Dagda is below 90% health, she may teleport a short distance away to perform this attack, but she will teleport straight back to the center afterwards so it may be worth just waiting for her to return.


Demonic Blast

At 90% health, Dagda will become untargetable for a few seconds, then fire out a conal attack in eight directions after a three-second delay, dealing very heavy damage to everyone hit. [does it also apply debilitated and residual agony?]

This attack repeats at 75%, 50% and 25% health (coinciding with phases), but is often skipped if she is performing another attack when the threshold is passed.

[does this attack also spawn tormented?]


Demonic Fever

Below 90% health, seven players are targeted with a medium-sized AoE that will explode after five seconds, dealing 20% of the targeted player's max health as damage to anyone inside. Players hit by multiple AoEs will take a further 200% of the their max health as damage, downing them.


Split Phase 1

At 75% health, Dagda becomes untargetable, repeats (maybe) and starts pushing players towards the edge of the arena while filling the middle with a large red AoE that ticks for 20% of a player's max health. The red AoE takes a long time to start dealing damage, and the split will frequently coincide with other mechanics so prioritise handling other mechanics correctly.


Groups with a lot of condi damage may wish to start moving towards the edge when Dagda hits 76%, to make mechanic overlaps easier to handle.


Two Tormented spawn near to each other at a random spot near the arena's edge. Kill them both to start the next phase.


Phase 2

Phase 2 is very similar to phase 1, with the addition of one new mechanic:


Soul Feast

Approximately 30 seconds into the phase, a random player becomes the target of , and receives the on-screen message: "You are targeted by Soul Feast. Run!"

A targetable, but undamageable, red puddle spawns on the player and follows them around for 15 seconds, dealing a small amount of damage and applying a stack of Residual Anxiety Residual Anxiety and Infirmity Infirmity to each player hit.

At the same time, two small white AoEs spawn nearby, and any player can run into them to receive a Special Action Key called [Purifying Light]. This ability is a single-use attack that will destroy the if it hits. Be aware that the attack can be body-blocked by Dadga, so aim carefully.

The puddle is difficult to see, and the targeted player only receives a text notification that they have been targeted. As the attack is also very dangerous, everyone should be alert for this mechanic.


The mechanic in this encounter applies stacks of Residual Anxiety Residual Anxiety, which last for three minutes. This debuff has no inherent effect, but if a player reaches 10 stacks they will switch sides and become hostile to the group. While hostile, players retain control of their movement but will be repeatedly Taunt Taunted onto other players. The hostility will end early if the player is downed, and it appears that the effect can be condi cleansed. Stunbreaking the Taunt Taunt will prevent the forced attacking, but the player will remain hostile and be Taunt Taunted again after a short duration.


s that have been hit by [Purifying Light] will remain visible until they expire, but no longer have any effect.


Unlike Phase 1, Dadga's attack patterns are fairly reliable in this phase:

Auto Chain x2 Auto Chain x2 Spinning Nebula Soul Feast Auto Chain Repeat


Split Phase 2

At 50% health, Dagda becomes untargetable again and repeats the split phase as before, only this time four Tormented spawn. As they spawn across a large area, it may be worthwhile sending half the group to one side of the arena, and the other half to the opposite side.


Phase 3

Phase 3 begins much the same as Phase 2, though spawns at around 25 seconds.


Rain of Comets

Approximately 30 seconds into the phase, Dagda raises an arm above her head and summons a Rain of Comets to pelt one half of the arena for five seconds, indicated by a large red AoE. For the entire duration, this area ticks for 25% of a player's max health.


Planet Crash

Approximately 45 seconds into the phase, Dagda raises her sword high and summons a massive orb of energy. The group has 10 seconds to break her defiance bar (strength:3600) or she will slam the orb into the ground, dealing 90% of each player's max health across the entire arena.

Breaking the bar will instead cause the orb to shatter, raining down energy around Dagda, but only dealing minor damage. Dagda will be Exposed Exposed for 6.5s after being broken.


In this phase, her attack pattern is:

Auto Chain x2 Auto Chain Spinning Nebula Soul Feast Auto Chain x2 Rain of Comets Auto Chain x2 Planet Crash (only if not stunned) Auto Chain x3 Spinning Nebula Rain of Comets Repeat


Split Phase 3

At 25% health, Dagda becomes untargetable again and repeats the split phase as before, only this time six Tormented spawn. As they spawn across a large area, it may be worthwhile sending half the group to one side of the arena, and the other half to the opposite side.


Phase 4

The final phase is identical to Phase 3.
