FFXIV Phantom Armor Guide: How The Arcanaut Set Works

Phantom Armor, officially the Arcanaut's Armor, is item level 745 gear that only matters inside Occult Crescent, boosting your main stat and adding a Special Attribute that scales up your Phantom Job action damage. It syncs above the zone's normal item level cap, so materia melds get ignored, but the raw stat bump more than makes up for that. If you have been ignoring this system because it "does not matter outside the zone," patch 7.55 is the moment to stop ignoring it, since North Horn adds further upgrades to the same gear.

This guide covers how FFXIV Phantom Armor currently unlocks and upgrades in South Horn, since the North Horn additions in 7.55 build directly on top of this same system rather than replacing it.

How To Get Your First Set Of Phantom Armor

The base Arcanaut's Armor is purchased from the Expedition Antiquarian in South Horn, with each piece costing 4,000 Enlightenment Silver Pieces. Silver Pieces come primarily from completing FATEs and Critical Encounters, so this currency builds up naturally while you are doing basically anything else in the zone, including your relic weapon grind.

The Final Upgrade And Forked Tower

The last upgrade tier is by far the hardest to obtain, since it requires Sanguinite, a material tied almost entirely to The Forked Tower: Blood. A full clear with all personal coffers opened hands out a solid chunk of Sanguinite, and defeating the Sanguine Recluse enemy in the overworld gives a smaller amount as an alternative source. In theory you can gather enough Sanguinite from the Recluse alone without ever entering the raid, but realistically it would take an extremely long time compared to just running Forked Tower.

If you have not touched Forked Tower yet, do not panic about the final armor tier right away. The +1 upgrade alone is a meaningful stat boost, and Forked Tower: Magic in patch 7.55 is being built with an easier normal mode specifically so more players can get through it without the coordination nightmare Forked Tower: Blood became known for.

Once you own a base piece, the Expedition Armorer can upgrade it to +1. Each upgrade costs the base piece itself, plus 3 Aetherspun Silver and 3 Aetherial Fixative. Aetherspun Silver is bought with Silver Pieces, while Aetherial Fixative costs Enlightenment Gold Pieces, the currency earned mainly by chaining mob kills rather than FATEs. Budget for both currencies if you want to push through this stage quickly.

Occult Accessories: The Other Piece Of The Puzzle

Beyond armor pieces, there are special item level 745 accessories split into disciple of war and disciple of magic sets, five each. These drop very rarely from Critical Encounters, overworld treasure coffers, Magic Pot coffers, and Happy Bunny coffers, and they are tradable on the market board, unlike most Occult Crescent rewards. Wearing a full set of five gives an additional bonus on top of each individual accessory's stat boost, making them a long term chase item rather than something to expect quickly.

What Changes In North Horn

Patch 7.55 confirms additional Phantom Armor upgrades tied to North Horn, continuing the same gear progression rather than starting a new system from scratch. Expect a similar pattern to what South Horn established: a purchasable base tier, a currency and material based mid upgrade, and a harder final tier likely tied to Forked Tower: Magic. Exact costs and materials for the North Horn tiers have not been detailed in official patch notes yet, so treat any specific number floating around before release as unconfirmed.

Final Word

Phantom Armor is not optional if you want your Phantom Job actions to actually hit hard, since the Special Attribute stat directly scales that damage. Get your base set and +1 upgrade sorted now using currency you are already farming for other reasons, and let the final upgrade tier come naturally once you are comfortable running Forked Tower content.
