1.1.

Dungeon Bonuses and How to Obtain them

Right when you defeat the first handful of non-boss-enemies, down to the library, there is an Arcane Tome which upon interaction gives you Arcane Empowerment Icon Arcane Empowerment buff, increasing your haste by 5% for 30 min (persists through death as well).

1.2.

Arcanotron Boss Guide

Arcanotron
1.2.1.

All Roles

  • If your Healer hasn't dispelled your Ethereal Shackles Icon Ethereal Shackles, use your defensives. Note that any immunity or self-dispel (like Stoneform Icon Stoneform) helps.
  • Be mindful of the Arcane Expulsion Icon Arcane Expulsion damage done, as well as the AoE knockback afterwards. This can be extremely dangerous if there is Arcane Residue Icon Arcane Residue left behind.
  • During Refueling Protocol Icon Refueling Protocol, do make sure to soak Energy Orb Icon Energy Orbs so they don't get consumed by the boss (it will trigger Arcane Empowerment Icon Arcane Empowerment, dealing group-wide AoE damage). Be cautious about how many Energy Orb Icon Energy Orbs you soak as they leave a stackable Unstable Energy Icon Unstable Energy debuff.
  • During Refueling Protocol Icon Refueling Protocol phase, the boss takes 20% increased damage, so use it to your advantage.
1.2.2.

Tank

  • Use your defensive cooldowns during Repulsing Slam Icon Repulsing Slam ability.
  • Move the boss away from any Arcane Residue Icon Arcane Residue so your melees can have better uptime.
1.2.3.

Healer

  • Dispel as many players as you can from Ethereal Shackles Icon Ethereal Shackles.
  • Top up players before each Arcane Expulsion Icon Arcane Expulsion.
1.3.

Seranel Sunlash Boss Guide

Seranel Sunlash
1.3.1.

All Roles

  • Use your defensives during Runic Mark Icon Runic Mark and get into the Suppression Zone Icon Suppression Zone to trigger Feedback Icon Feedback and clear the debuff (dodge the incoming arcane barrages on the ground). Be mindful of the following Null Reaction Icon Null Reaction stackable debuff, as that will make it much more difficult to dodge any ground ichors.
  • Before Seranel Sunlash finishes its Wave of Silence Icon Wave of Silence cast, be sure to be under the Suppression Zone Icon Suppression Zone to avoid being silenced and taking unnecessary damage.
1.3.2.

Tank

  • If your party doesn't help you dispel the Hastening Ward Icon Hastening Ward from Seranel Sunlash, use your major defensive cooldowns.
1.3.3.

Healer

  • Spot-heal people that have Runic Mark Icon Runic Mark debuff and use your externals where appropriate.
1.4.

Gemellus Boss Guide

Gemellus
1.4.1.

All Roles

  • At the start of the fight and at 50% of its HP, Gemellus, will cast Triplicate Icon Triplicate. All of its copies share health so the more you attack, the faster the boss will die.
  • If you get Neural Link Icon Neural Link debuff, make sure to hug the right copy of the boss to remove its shield and clear the debuff.
  • During Astral Grasp Icon Astral Grasp channel, use any movement-increase effects to avoid being hit by the Cosmic Radiation Icon Cosmic Radiation aura, which is within hit range of the boss.
1.4.2.

Tank

  • Try to get close to as many copies of Gemellus as you can to speed up the boss fight.
1.4.3.

Healer

  • Be mindful when Cosmic Sting Icon Cosmic Sting happens as the follow-up effect of Void Secretions Icon Void Secretions will hurt if people are slow to reposition.
  • Spot-heal people that get inside the Cosmic Radiation Icon Cosmic Radiation, as not every class has the movement-speed increase to help overcome the Astral Grasp Icon Astral Grasp channel.
2.

Degentrius and Trash Mobs in the Area

2.1.

Degentrius Boss Guide

Degentrius
2.1.1.

All Roles

  • Spread your team-mates through the entire room, each covering 1 of the "pizza-slices" around the boss, so you can bounce the Unstable Energy Icon Unstable Energy ball. Do keep in mind that if you miss, the whole party will get Void Destruction Icon Void Destruction stackable debuff, more than 1 stack usually results in a wipe.
  • Make sure to never touch the Void Torrent Icon Void Torrent beams outlining the "pizza-slices".
2.1.2.

Tank

  • Be mindful not to "clip" your party during Hulking Fragment Icon Hulking Fragment cast as it will likely one-shot them. Try to have good space management when you're trying to get rid of your Umbral Splinters Icon Umbral Splinters debuff as it leaves Stygian Ichor Icon Stygian Ichor and can be tough to walk through as a DPS.
2.1.3.

Healer

  • Use your major healing cooldowns during Devouring Entropy Icon Devouring Entropy debuff, as this can be particularly difficult on any DPS players if they have to soak simultaneously Unstable Void Essence Icon Unstable Void Essence.
