Final Fantasy 14: The Porta Decumana Trial Guide

The climax of the A Realm Reborn expansion in Final Fantasy 14 used to be a bit different from what it is currently. Players would go through a huge dungeon filled with tons of dialogue that could last for a literal hour to witness the story's final moments in The Praetorium.

But this was changed during the Endwalker expansion, where this huge dungeon was split into a more condensed version, with the final fights now available in the Porta Decumana Trial. Available through the Main Scenario Roulette, this story-based Trial is a fitting end to the game's very first storyline.

How To Unlock Porta Decumana

The Trial is automatically unlocked after completing The Praetorium dungeon. Both are obtained during The Ultimate Weapon quest, the final one in the A Realm Reborn MSQ, so you'll automatically have access to it by simply advancing in the game.

You can enter it through the Duty Finder, and can also randomly get it during Main Scenario Roulettes. Some cutscenes are unskippable.

Porta Decumana doesn't appear in the regular Trials Roulette.

Porta Decumana Guide

Porta Decumana is a bit different from other Trials so far as it's more of a final spectacle than a proper fight during its first minutes. The first phases are semi-automatic, and damage is only really required for the final phase.

The Ultima Weapon will use its three Primal's attacks, cycling between them after exhausting their powers in an attempt to defeat you. Once it's out of Primals, the battle shifts to the final phase after a cutscene. Here are all the attacks for the whole encounter:

Primals Phase

At the beginning of the battle, you'll face the Titan-enhanced Weapon:

Attack	Type	Description
Earthen Fury	AoE	Raidwide damage on all players.
Geocrush	Proximity AoE	Marks a point on the arena to deal AoE damage. Move away from the marked point to reduce damage taken.
Landslide	Line AoE	Summons Titan to use its signature smash on the ground. The Weapon itself will later repeat the attack.
Weight of the Land	Circle AoE	Various circle AoEs appear across the room. Dodge them as needed.
Granite Interment	Special	Used once it reaches 80% HP. Locks down all players inside gaols. It later attempts to use Earthen Eternity, but fails and loses Titan's powers.

After losing Titan, it'll shift to Garuda:

Attack	Type	Description
Aerial Blast	AoE	Raidwide damage on all players.
Eye of the Storm	Circle AoE	Covers part of the arena with a blue circle, leaving only a safe spot in the middle.
Mistral Shriek	Circle AoE	After using Eye of the Storm, summons Garuda to use an AoE around herself. Stand away from her but inside the safe zone in the middle.
Vortex Barrier	Special	Used around 55% HP. Becomes invincible to all attacks. It attempts to use Headman's Wind, but fails and loses Garuda's powers.

Attack Type Description Aerial Blast AoE Raidwide damage on all players. Eye of the Storm Circle AoE Covers part of the arena with a blue circle, leaving only a safe spot in the middle. Mistral Shriek Circle AoE After using Eye of the Storm, summons Garuda to use an AoE around herself. Stand away from her but inside the safe zone in the middle. Vortex Barrier Special Used around 55% HP. Becomes invincible to all attacks. It attempts to use Headman's Wind, but fails and loses Garuda's powers.

Lastly, it'll use Ifrit against you:

Attack Type Description Hellfire AoE Raidwide damage on all players. Radiant Plume Circle AoE Similar to Titan's Weight of the Land, but fire-themed. Dodge in a similar fashion. Vulcan Burst Knockback Ifrit appears in the center of the arena and pushes all players back. Stay next to him at the center after he appears. Radiant Blaze AoE Used once the Weapon is around 30% HP. Launches an unavoidable attack covering the whole area. You'll be shielded once again, and can burst down the Ultima Weapon. Attack	Type	Description
Hellfire	AoE	Raidwide damage on all players.
Radiant Plume	Circle AoE	Similar to Titan's Weight of the Land, but fire-themed. Dodge in a similar fashion.
Vulcan Burst	Knockback	Ifrit appears in the center of the arena and pushes all players back. Stay next to him at the center after he appears.
Radiant Blaze	AoE	Used once the Weapon is around 30% HP. Launches an unavoidable attack covering the whole area. You'll be shielded once again, and can burst down the Ultima Weapon.

You can still attack the Ultima Weapon during his Radiant Blaze cast. Once Ifrit is out, keep attacking the boss. After it loses enough health, it triggers a new unskippable cutscene, entering the final phase of the fight:

Ultima Weapon Phase

The Weapon uses a variety of moves here, but none are considerably lethal:

Attack	Type	Description
Homing Lasers	Tankbuster	Attacks the main target with lasers. Must be mitigated.
Homing Ray	Target AoE	Targets all players with a circle AoE. Stay away from each other and heal after it explodes.
Tank Purge	AoE	Raidwide damage on all players.
Aetheric Boom	Special	Pushes all players back and summons two pairs of orbs tethered to each other. Touch them to pop them before they encounter each other.
Laser Focus	Stack AoE	Stack damage targeted at the healer. The whole party must stack with them.
Citadel Buster	Point-Blank AoE	A direct laser in front of the weapon, immediately after the previous attack.
Magitek Bits	Special	Summons various mechanical laser shooters across the room. Dodge them as usual.
Explosion	Proximity AoE	Uses four proximity markers at each corner of the arena. Run center and wait until they explode, then dodge again as the Weapon follows up with another Citadel Buster.

After Explosion, the Weapon simply repeats its attacks with nothing new, sometimes overlapping some of these attacks, so be careful. It only gets a final attack once it reaches 30% HP:

Attack Type Description Ultima AoE After reaching around 30% of its HP, the Ultima Weapon attempts to use Ultima again. At the same time, you'll be granted a full Limit Break 3. Any DPS (Melee preferably) should use it to defeat the Weapon once and for all. Don't bother about healing and just kill it. Attack	Type	Description
Ultima	AoE	After reaching around 30% of its HP, the Ultima Weapon attempts to use Ultima again. At the same time, you'll be granted a full Limit Break 3. Any DPS (Melee preferably) should use it to defeat the Weapon once and for all. Don't bother about healing and just kill it.

Once it starts its final Ultima attack, you'll receive the Limit Break bars once the dialogue ends. A DPS Limit Break 3 must be used to meet the DPS check. Otherwise, you'll be wiped and have to restart from the Ultima phase once again.

Porta Decumana Rewards

There are no specific rewards for clearing Porta Decumana. However, the Main Scenario Roulette is notable for granting some of the best experience points out of all Roulettes in the game. It can take a bit longer than other duties, but it's worth it when leveling your Jobs.
