Dungeon Walkthrough

Mt. Gulg can be attempted using the Trust system, which will allow you to enter the dungeon with three Scions of your choosing. While considerably slower than other players, the Trusts are useful for helping you learn the mechanics of the dungeon. They will move to safe spots and give call-outs for dangerous mechanics, which can be helpful on the first run-through of the dungeon.

Later in the dungeon, you will encounter the Forgiven Revelry mini-boss. This enemy will raise its left or right hand in preparation for a large attack to that side of the arena. Move accordingly to avoid taking damage. Additionally, white orbs around the arena will periodically fire line AoEs at party members which need to be dodged.

Forgiven Cruelty

The first boss of Mt. Gulg is Forgiven Cruelty. Vauthry's pet sin eater will be the first challenge of this dungeon, whose attacks and mechanics are detailed below.

  • Rake: Deals high damage to the Tank. Use defensive abilities to mitigate the damage of this attack.
  • Lumen Infinitum: Forgiven Cruelty will fly into the air and target a random player. Then, the boss will fire a beam at the targeted player's direction, dealing massive damage in a line. When the boss flies into the air, move away from its front to avoid this attack.
  • Typhoon Wing: The boss will fly into the air and create wind spheres in a pattern immediately beneath the boss. As the boss lands, the wind spheres will fire, dealing damage in a cone shape away from the boss. Position yourself between the spheres to avoid being hit.
    • Orbs: Later in the fight, when the boss casts Typhoon Wing, additional wind orbs will appear around the arena, including directly underneath the boss. These will explode in a large circular AoE at the same time as the wind spheres from before, so you will need to position yourself between both sets of AoEs to avoid being hit.
  • Cyclone Wing: Deals damage to all party members. Use AoE heals to recover.

Forgiven Cruelty will repeat these attacks until it is defeated. Subsequent uses of Typhoon Wing can take a while to get used to, so try to play cautiously during this attack.

Forgiven Whimsy

The second boss of Mt. Gulg is Forgiven Whimsy, who takes the appearance of a sin eating Rubix cube. You may notice the arena has a similar appearance, which will be used throughout the fight. Forgiven Whimsy's attacks and mechanics are listed below.

  • Sacrament of Penance: Deals damage to all party members. Quickly recover with AoE heals.
  • Exegesis: Forgiven Whimsy will use this attack throughout the fight. The boss will change its shape, moving its faces around the cube before settling on one pattern. Then, after a moment, the squares on the arena that correspond with a face on the boss will take damage. You will need to watch the pattern on the boss, determine which squares will be attacked, and move accordingly to deal with this attack. There are several different forms the boss can take, so watch carefully.
    • Orbs: Later in the fight, white orbs will additionally appear on the arena during Exegesis. These will cast large ring-shaped AoEs, further limiting the safe area during the attack. Avoid the orb's AoE attack while also moving to the safe spot out of Exegesis.
  • Catechism: Deals damage to the Tank. Use defensive cooldowns to mitigate.
  • Judgment Day: The boss will call down two meteors to the arena. At least one player needs to stand underneath the meteor's AoE zone to absorb the damage of it, otherwise, the meteor will explode and deal high damage to all party members. Make sure two players are on top of running underneath the meteors as they appear.

Forgiven Whimsy will repeat these attacks until it is defeated. Exegesis can be difficult to get used to, but after a few uses of the attack you should be able to get the hang of it. After defeating Forgiven Whimsy, only one boss remains.

Forgiven Obscenity

The final boss of Mt. Gulg is Forgiven Obscenity. This enemy will use a variety of AoE attacks, so prepare to move. Listed below are each of the boss's attacks and mechanics.

  • Orison Fortissimo: Deals damage to all party members. Heal as necessary.
  • Divine Diminuendo: Creates a point-blank AoE around the boss. Move away from Forgiven Obscenity to avoid.
    • Vauthry's Blessing: Vauthry will grant his blessing to the boss, adding a mechanic to Divine Diminuendo. Now, as soon as the point-blank AoE explodes, a second ring-shaped AoE will also explode. There will be a small safe area between the point-blank AoE and the ring AoE, so try to stay just outside the point-blank AoE to avoid both of these attacks.
  • Conviction Marcato: Forgiven Obscenity will begin charging an attack that hits in five directions; one line AoE to her front, and four line AoEs to her intercardinal directions. These AoEs will be indicated by golden circles that appear around the boss. Move away from the area the circles are facing to avoid this attack.
  • Penance Pianissimo: The boss will cover the edges of the arena in a puddle AoE, limiting the safe zone to a circle.
  • Feather Marionette: Forgiven Obscenity will summon four clones around the arena that will repeat her AoE attacks. Keep in mind that the true Forgiven Obscenity will still have Vauthry's Blessing for this attack, indicated by the glowing halo on the boss. Forgiven Obscenity and her clones will use both of the following attacks before the clones disappear.
    • Clone Divine Diminuendo: All five clones will deal damage in a point-blank AoE around themselves. The clone of the boss that has Vauthry's Blessing will have the additional ring AoE from before, which must be avoided in the same way. Move close to the clone with Vauthry's Blessing (but not too close) to avoid these AoEs.
    • Clone Conviction Marcato: All five clones will deal damage in line AoEs to their intercardinal directions. Stand to the left, right, front, or back of the clone in the center of the arena to avoid these AoEs.
  • Solitaire Ring: Forgiven Obscenity will move to the top of the arena before summoning six glowing orbs at the edge. Then, she will place a ring in front of each orb at varying distances. The orbs will then travel slowly down the arena, and when they reach a ring, will explode in a line AoE. Move in front of the ring that is furthest from its orb to avoid the first orbs, then move into the previously unsafe area to avoid the rest.
  • Sacrament Sforzando: Deals high damage in a line towards the Tank. Use defensive cooldowns and face the boss away from the rest of the party for this attack.

Forgiven Obscenity will repeat these attacks until she is defeated. There is a lot to keep track of during this fight, but if you play it safe you should be able to defeat her.
