A sigil is a type of upgrade component that can only be used on weapons. Like all upgrade components, attaching a sigil to a weapon will make that weapon soulbound, it will replace any existing component in the upgrade slot, and it has a chance of being recovered when the weapon is salvaged. Sigils can be crafted by artificers, huntsmen, or weaponsmiths.
 Sigil tiers
There are three tiers of sigils, Minor, Major, and Superior, with the higher tiers having stronger effects. Each tier has a level requirement, which refers to the minimum level of weapon to which the sigil can be attached.
- Minor sigils have no minimum level.
- Major sigils require a level 39 weapon or above.
- Superior sigils require a level 60 weapon or above.
 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.

For professions that do not have access to weapon swapping:
- Elementalists trigger these sigils when changing attunement.
- Engineers trigger these sigils when equipping or stowing a kit.
|Sigil of Battle||Gain 2 / 3 stacks of Might for 20 seconds on weapon swap|

- Sigil effects are not restricted to the respective weapon's skills. For example, a Sigil of Force on an off hand weapon will also increase the damage of mainhand skills or utility skills.
- Sigils continue to function while holding a bundle, such as engineer kits. In several cases, both equipping and dropping them in combat also counts as a weapon swap.
