Legion Boss Guide: Helya

As usually, these tactics are my own and does not mean they are the most optimal.

Helya is the last Raid boss in Trial of Valor, patch 7.1

Background Story

Though she once served as Odyn´s right hand, the vengeful Helya will stop at nothing to ensure her ancient curse binds the titan keeper to the Halls of Valor. No longer satisfied with ruling her shadowy realm, Helya now commands her vast kvaldir army to plague the lands of the living.

Overview

The platform is divided in one main in the middle and 2 smaller ones on left and right side of stairs.
The fight is divided in 3 phases
Phase 1: Boss has 5 abilities.
Phase 2: Boss swims away but does some abilities. Main event is the adds that spawns and tentacles that needs to destroyed to get the boss back again.
Phase 3: Is a combination between phase 1 and phase 2 abilities/events.

Phase 1 – Low Tide

Helya has 5 abilities in this phase

Positioning Phase 1

Tanks
Stand on each side of boss opposite from each other.

Melee
Stand spread on the center of boss.

Ranged
Stand spread on the center further back from boss.


Orb of Corruption

Boss targets several players and shoots an Orb at them
This Orb fixates that player and does pulsating dmg while moving.
Taking dmg from an Orb gives a stacking debuff that increases dmg taken from orbs by 100%.

Tactic: Orb of Corruption

Move away from the Orbs, away from raid.
Beware of the Breath boss does on tank direction so you don’t get hit.

 


 

Bilewater Breath

Boss does a breath on main tank location in a frontal cone that does very high dmg.
The breath does 2 things:

  • Applies a debuff on tank (anyone getting hit) by breath.
    This debuff decrease armor by 100% for 30 sec.
  • Several slimes (Bilewater Slimes) will land on the breath location.
    Each slime does dmg within 5y when they land on the ground.
    Each slime will burst after 20 seconds and do deadly dmg to ALL players.
    The health left of a slime reduces the dmg a slime does when bursting.
    After bursting, each slime leaves a pool (pool size also depends on health left).
    The pool does moderate dmg every second for 45 s, if a player stands on it.

Tactic: Bile Water Breath

Tanks
One tank on each side of boss.
The breath will hit the left or right side of the platform depending on who is tanking.
Tank swap after each breath.
Use def CD at breath.

DPS
Every single dps needs to focus on the slime and kill them asap.

Healers
Get ready to heal up players after slimes burst if not all are killed.
Some player/s will maybe touch the pool afterwards and needs a lot of healing.

Raid
Move away from the pools on the ground after slimes burst.


 

Tentacle Strike

A big Tentacles spawns either in front of the boss or on the opposite side of platform.
The tentacle slams the ground doing deadly dmg but is shared amongst players.
If no one takes the slam, the slam will send a shockwave that does deadly dmg to all players.

Tactic: Tentacle Strike

Melee
Stack in front of tentacles when they spawn near boss.

Ranged
Stack in front of tentacles when they spawn behind on the opposite side of boss.

Raid
Help front/back tentacles slams as well. Especially depending on how many melee/ranged you have in the raid.

 


 

Taint of the Sea

Boss puts a debuff on random player that does Frost dmg every second.
When the debuff is dispelled, it explodes does low dmg to all players.
When the debuff is dispelled it will also leave an essence under the player that explodes after a while and does high dmg to anyone within 8 yards.

Tactic: Taint of the Sea

Everyone stand spread at least 8 yards.
Dispel the taint directly.
Player dispelled moves away from the essence and then moves back after explosion.


 

Corrosive Nova

If no players are in melee range, the boss will cast Corrosive Nova which does 2 things:

  • Blasts every player with Frost damage
  • Gets a buff that increase Helyas dmg by 3% and stacks

Tactic: Corrosive Nova

Melee and tanks

Make sure there is ALWAYS someone in melee range on boss.

Corrupted Breath

Boss breath Shadow, dealing high dmg.
If the breath doesn’t hit any target, it will explode and do dmg to all players instead.

Breath causes shadow pools to spawn on random locations on the platform (Axions).
The Pool does dmg and a healing absorption to players within 5y of affected player for a few seconds.
If no player stands on the pool, it will apply Axion dmg to all players instead.

Tactic Corrupted breath

Make sure you are on left side with breath, use def CD for breath.
No other player behind/close

Healers
Beware that tank gets high dmg from the breath.

Run to a shadow pool fast and soak it.
If a player is ready to soak and gets Orb targeting that player, be ready to take over the soak so that player can run away with Orb instead.

This Orb fixates that player and does pulsating dmg while moving.
Each pulse leaves a green pool on the ground (Decay) that does dmg if you stand on it.

Plan your path so you use as much of right side of the platform as possible.
Use the bottom side of the platform as well when needed.
Leave left side and middle free from pools.
