A sigil is a type of upgrade component used in weapons. Like all upgrade components, attaching a sigil to a weapon of masterwork, rare, or exotic rarity will make that weapon soulbound; fine or basic weapons will become account bound. You can replace a sigil with a new one or attempt to recover it by salvaging the item.
 Sigil tiers
There are three tiers of sigils, Minor, Major, and Superior, each with its own minimum level requirement.
- Minor sigils have no minimum level.
- Major sigils require a level 39 weapon or above.
- Superior sigils require a level 60 weapon or above.
- Certain sigils can be crafted by artificers, huntsmen, or weaponsmiths. Most of these can be learned through discovery, but several require obtaining the relevant recipe.
- All crafted and most salvaged sigils can be purchased on the Trading Post.
- Some sigils are available from the dungeon equipment vendors.
- Most sigils can be recovered from armor by salvaging it; only Black Lion Salvage Kits are guaranteed to produce the sigil.
- You can combine four sigils of the same tier in the Mystic Forge, with an 80% chance of receiving a random sigil from the same tier and a 20% chance of it being the next higher tier. While all minor and major sigils can be combined this way, the forge only returns a subset of those sigils.
 Sigil interaction
A character can always equip two sigils at a time (either one sigil each on a main-hand and off-hand weapon, or two sigils on a two-handed weapon). In general, the two sigils will both provide their effects independently as long as the base sigil is different. The exceptions to this are the stacking sigils: only one stack effect can be active at a time.
- A warrior is wielding a greatsword with both a Superior Sigil of Air (chance to deal additional damage to target on hit) and a Superior Sigil of Earth (chance to inflict Bleeding on hit) attached to it. Both sigils will roll their chance to activate on every attack the warrior makes, and each sigil will run its own cooldown timer after it activates.
- A thief is wielding a main-hand dagger with a Minor Sigil of Agony (+5% Bleeding duration) and an off-hand pistol with a Major Sigil of Agony (+7% Bleeding duration). Only the major sigil's effect will apply, giving the thief +7% bleeding duration.
- A mesmer is wielding a scepter with a Minor Sigil of Bloodlust (gain a stack of +Power for every kill) and a focus with a Major Sigil of Perception (gain a stack of +Precision for every kill). The main-hand's stacking sigil will take precedence, and the mesmer will only gain stacks of Bloodlust.
