Astrologian Job Guide for FFXIV — Endwalker 6.55

Astrologian (AST) is a healer that draws inspiration from tarot and astrology, using cards from its divining deck to bolster its allies' damage.

Astrologian has a fast-paced, interactive playstyle with the busy and random nature of cards. Drawing, optionally redrawing, and playing each card takes several inputs and fast target swapping, making Astrologian one of the busiest jobs in the game. The randomness of cards also means that some decisions must always be made in the moment. Cards are all about making the best of what you have in any situation, which makes the job very dynamic, as no two pulls are exactly alike.

To unlock Astrologian, you must gain access to the city of Ishgard by completing the final Main Scenario Quest of A Realm Reborn, "Before the Dawn." The Astrologians' guild (the Athenaerium Astrologicum) can be found in Ishgard in The Pillars (X:15.2, Y:10.0). Accept the quest "Stairway to the Heavens" from Jannequinard. Upon completing the quest, you will unlock Astrologian, which starts at level 30.

The Arcana Gauge displays your currently held cards from Draw (major arcana) and Minor Arcana, as well as the astrosigns (sometimes called "seals") you have accumulated.

There are six cards you can Draw. Three of them are for melee jobs (including tanks), and the other three are for ranged jobs (including casters and healers). Each card provides a 6% damage buff for 15 seconds when played on a job of the matching role. If the card is played on someone of the opposite role, the buff is reduced to 3%.

Ranged/caster/healer cards have a purple outline and circular symbols to the sides in the Arcana Gauge, as shown on the left ( The Bole, The Ewer, and The Spire).

Melee/tank cards have a light blue outline and plus-shaped symbols to the sides in the Arcana Gauge, as shown on the right ( The Balance, The Arrow, and The Spear).

Starting at level 50, each card also has an associated astrosign, which is displayed at the top of the card in the Arcana Gauge, as shown above. There are three different signs, with one melee and one ranged card for each. It may help to think of the cards in melee/ranged pairs, with one pair for each sign. When you Play a card, its sign is added to the top of the gauge, as long as you and the recipient are both in combat.

Once you have three signs, you can use Astrodyne, consuming them in the process. Astrodyne always provides MP regeneration. It can give additional buffs based on the number of unique (non-duplicate) signs you have, providing all three buffs when used with one of each sign.

At level 70, you unlock Minor Arcana, which adds the smaller space on the right side of the Arcana Gauge. Using Minor Arcana will give you a Lord of Crowns or Lady of Crowns, at random.

The Lord or Lady of Crowns is displayed on the right side of the gauge once it has been drawn. It can then be played by pressing Minor Arcana again, as the button is replaced with the Lord or Lady.

Ever has man coveted knowledge, and none more so than that of his fate. Thus did he labor to master the skill of foresight—but initial efforts bore little fruit. That is, until he looked to the stars above, which foretell the coming seasons, and learned to read the heavens.

Though this gift is known today as astrology, the people of Sharlayan saw fit to not only read the stars, but to write their movements as well. By attuning their aetherial energies to that of constellations, they learned to wield magicks with heretofore unseen properties.

Thus was astromancy born—a new form of magick which grants its users power over fate. Employing a star globe and divining deck in their miraculous deeds, fortune always smiles upon these masters of arcana.
