Sentient Weapon/Filigrees

Filigrees are ingredients, found during questing, that can be added to a Sentient Weapon to increase its power. They work in a similar manner to augments, i.e. a filigree fits into an open slot on the weapon. A weapon can only have one of each filigree: two of the same filigree cannot be slotted in one weapon (rare and non-rare versions of the same named filigree count as the same for slotting purposes).

Filigrees are unbound, and can be traded and auctioned. Filigrees can be (auto-)collected into an augment bag, and can be found under "Item Augments" in the Auction House and Shard Exchange.

A Sentient Weapon is created by adding a sentient jewel to an eligible weapon, and starts with one open filigree slot. More filigree slots are created by feeding named items to the sentient jewel, to a maximum of 7 slots. An 8th slot can be unlocked using.

Filigree Sets
Filigrees are grouped into sets. When more than one filigree from the same set is added to a single weapon, additional Set Bonus benefits are gained. Further benefits are gained as more filigrees are added. Some sets only grant Set Bonuses for the first 3 pieces of a set added to the weapon; other sets grant additional Set Bonuses at 4 and 5 pieces. There are always more pieces to a set than there are set bonuses, allowing choice in the filigrees slotted to achieve the Set Bonus.

There are well over two dozen different filigree sets: Unless specifically noted, all bonuses listed are unique bonuses and stack with everything, including other unique bonuses: Several powerful raid filigrees can be purchased for Threads of Fate. Unlike regular filigrees, each raid filigree belongs to two filigree sets.
 * Each set has from 4 to 9 unique filigrees in it
 * Different filigrees vary in rarity - some sets are less common than others
 * Filigrees from rare sets are not labelled as such - they are, however, noted in the list below
 * All filigrees can drop with a rare bonus effect in addition to the standard one e.g. Celerity: Dexterity can also drop as Celerity: Dexterity (Rare)
 * Filigrees with rare bonus effects are labelled (Rare) in the item name, with the bonus effect listed in addition to the standard effect
 * Filigrees with the same effect from the same set cannot be added to the same Sentient Weapon and thus do not stack
 * Filigrees with the same effect from different sets can be added to the same Sentient Weapon and do stack (unless noted otherwise)

Generations
Over time new groups or Generations of filigree sets are released. Each Generation of filigrees drops in the chests from a limited series of adventure packs (listed in the tables below).
