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)
