This system becomes available after you talk with Shiftrix the first time. You need to flag Darkness Beckons before you can enter Reisenjima.
Augments in FFXI are placed into "slots" on items.
In the case of augmenting armors from Reisenjima with Pellucid Stones ( P), Fern Stones ( F), and Taupe Stones ( T), there are 5 slots that are used whose caps and probability of occurring varies between the different stones.

Oseem in Norg (I-7) is in charge of this process and is also able to store the stones.

The slots used for augmentation are:

• Slot 1: 60% chance of this slot occurring.
  • When it occurs, the distribution is approximately Attack (40%), Accuracy (40%), or Attack / Accuracy (20%)
  • Forced to occur (100% chance) via Pellucid Stones.
    • There is no immediately apparent additional effect of Pellucid Stones, although they may make the combined Attack / Accuracy augment more common.
  • Cap is 30 for on-path Accuracy and Attack, and 25 for the combined augment and off-path Accuracy and Attack.
  • Distribution is flat. You are just as likely to get the maximum value as the minimum value.
  • Varies based on path (ie. Magic path would have Magic Attack, Magic Accuracy, and Magic Attack/Accuracy).
  • "Off-path" augments occur with a 10% rate. The combined Attack/Accuracy off-path augment is not possible.

• Slot 2: Job-trait or "special" stats, like Physical Damage Taken, Store TP, DA or TA, WSD, etc.
  • Forced to occur via Fern Stones.
  • Cap varies from stat to stat, and are increased by 1 when using Fern Stones.
  • Higher values are less likely than lower values. With Fern Stones, the probability of a maximum potency augment is approximately 3%.
  • There are 8 different augments for each armor that depend on the path.
    • "Off-path" augments (10% rate) manifest in the form of Physical Damage Taken, Magic Damage Taken, and Damage Taken augments.

• Slot 3: Base stats
  • Forced to occur via Taupe Stones.
  • Cap is 10 normally, or 15 under the effect of Taupe Stones.
  • Distribution is flat. You are just as likely to get the maximum value as the minimum value.
  • The 3 on-path base stats vary based on path and armor, but off-path augments are possible with a low probability (10% rate).

• Slot 4: Accuracy
  • Cap is 15.
  • Probability of occurrence is 40% and cannot be forced.
  • Distribution appears flat.
    • It is possible that if the combined total of Slot 1 and Slot 4 exceed 40 Accuracy, the Slot 4 augment will be dropped.
  • There are no off-path augments for this slot.

• Slot 5: Attack
  • Cap is 15.
  • Probability of occurrence is 40% and cannot be forced.
  • Distribution appears flat.
    • It is possible that if the combined total of Slot 1 and Slot 5 exceed 40 Attack, the Slot 5 augment will be dropped.
  • There are no off-path augments for this slot.

• Dark matter: Specialized augments
  • Dark Matter, which has its own category called "technique" currently has very little information available due to the high cost of dark matter which is used in upgrading equipment to iLv119 and crafting.
  • Current known information is that it provides stats from all category such as melee,magic,ranged and pet completely randomly whiling mixing stats (E.g. Ranged attack with pet attack with int stat) with a chance to go over the cap set on normal stones (Be aware that its extremely rare)(E.g. WS dmg +9 or Mattack +50)
  • Currently suspected that all 5 slots can have any stats appear that would normally stay in a certain slot.
  • It makes every stat type from all armors available to any armor type (e.g.Valorous stats on Merlinic armor).
  • It also has specialized stats including but possibly not limited to, quadruple attack +1-3, Phalanx +1-5, TH +1-2, refresh +1-2, weaponskill damage +1-10%, etc

In the augment tables below, On-path augments are indicated using the bold font weight, while F and T indicate cap changes based on Fern and Taupe stones respectively.

Note! All of the equipment below has the "AugSendable" tag. This means that they can be sent to alternate characters on the same PlayOnline account, even after they are augmented!

Monthly Adventurer Campaigns

There is one type of campaign that may run any given month. Either below may be running, but both dont run at the same time.

Dark Matter Arcane Glyphics Campaign

• When this Monthly Adventurer Campaign is active, six free "Technique" augments are available every earth day via Oseem.
  • Through the power of Arcane Glyptics, Reisenjima armor drops can be engraved for free up to six times per earth day at no charge. The only requirement is that you are on or past Rhapsodies of Vanadiel Mission 3-1.
    • Dark Matter augments are highly random, and sometimes surpass the maximum values of Taupe, Pellucid, and Fern stones. This is the way players obtain Treasure Hunter and Refresh on pieces that normally do not have it.
  • The equipment will receive the same benefits as if they were engraved with Dark Matter.
  • Visit Oseem in Norg at (I-7) to engrave your equipment. This resets every day at JP Midnight.
  • Note: This campaign usually starts at 1AM Pacific time on the months it runs. This essentially gives six extra augments before the JP Midnight reset 6-7 hours later after the campaign starts. Be sure to take advantage of this!

Dark Matter Arcane Glyphics Campaign - PLUS!

• When this Monthly Adventurer Campaign is active, twelve free "Technique" augments are available every earth day via Oseem (instead of six from the NQ campaign).
  • The other details of this campaign are the same as the NQ version described above.
  • Note: As of the September 10, 2020 version update: On the day of the switchover from the normal Dark Matter Arcade Glyphics Campaign to Dark Matter Arcade Glyphics Campaign PLUS, the number of times you may augment an item will increase even if you have already augmented items that day.
