How to Avoid Death Sentence

Heliber Mechanics
Reduce the Damage by Stacking Use Salvation Chain to Pull Allies

Reduce the Damage by Stacking

You can reduce the incoming damage of the Death Sentence by grouping together within its radius, sharing the damage among all the players inside.

Use Salvation Chain to Pull Allies

Players using the staff can activate the Salvation Chain to pull teammates out of the Heliber's range, helping them dodge its attacks. Since this attack can deal massive damage, be mindful of your teammates' positioning at all times to save them when the Heliber is about to swing its scythe.

Heliber Attack Patterns

AoE Cone Attack

Heliber raises its scythe and slams it into the ground, releasing projectiles that fan out in a cone. You can immediately morph and strafe sideways to move out of the cone's range.

AOE Fury Attack

Heliber releases a fury attack that damages players over a wide area. You can mitigate the damage from this attack by successfully parrying with your defensive skills.

Specter's Abyss Walkthrough

	Specter's Abyss Sequences
1	Defeat Elite Arkeum Shadowmancer After clearing the first room of enemies, proceed into the hallway. There, players will find a smaller group of enemies. Defeating them will spawn the Elite Arkeum Shadowmancer. Defeat the miniboss to progress further into the dungeon. ┗ How to Defeat Elite Arkeum Shadowmancer
2	Pull the Levers Entering the hall past the corridor, the path forks in two. Clear the enemies in both areas and pull the levers in the middle of the rooms. This will make the area in the middle accessible.
3	Defeat Elite Arkeum Riot Squad Captain Before proceeding to Heliber, clear out the room of any enemies, including the Elite Arkeum Riot Squad Captain standing guard at the entrance to the boss room. ┗ How to Defeat Elite Arkeum Riot Squad Captain

How to Defeat Elite Arkeum Shadowmancer

When fighting the Elite Arkeum Shadowmancer, the only attack of note is the one that inflicts Silence on a player in the party, causing them to become immobile and unable to perform actions. Inflicting CC on the Shadowmancer will dispell the silence.

How to Defeat Elite Arkeum Riot Squad Captain

The Elite Arkeum Riot Squad Captain has a tendency to perform an attack that could potentially wipe teams. To counter this, when it begins charging, burst the shield with skills. When it breaks, inflict CC on the Riot Squad Captain to interupt the attack.

Alternatively, if the team cannot break the shield in time, gathering around the Healer or Tank for them to cast a team-wide shield can help the team survive..
