Types of summoned allies
- Spirit weapons
- Spirit Weapons are ghost-like allies summoned by guardians using utility skills. After creating a spirit weapon, the summoning skill is replaced by a sequence skill that will cause the spirit weapon to perform a powerful attack. Guardians can maintain up to three spirit weapons each of which follow the caster and can be attacked by foes; these allies survive for 20 seconds, or until it is killed.
- Nature spirits are immobile spirit allies summoned by rangers. Each spirit provides a passive buff to nearby allies and enables a sequence skill used to harm foes or support allies.
- Fellow thieves
- Fellow thieves are summoned by thieves using various skills and once summoned they will fight alongside the player until slain or their duration expires.
- Elementals are summoned by elementalists using a Glyph of Elementals or Glyph of Lesser Elementals; the type of elemental is determined by the caster's current attunement: air, earth, fire, and water. Elementals last for 60 seconds or until slain.
- Illusions are mind tricks that mesmers manifest physically using a weapon or utility skill, and they have the same appearance as its caster; although, they are usually directed at a specific target, anyone can see and attack them. They can only exist so long as their target is alive and can only be dispelled by the caster or by foes attacking the illusion(s). Mesmers can maintain up to three illusions at any one time with newer ones replacing the oldest ones regardless of the health of the existing summons.
- Minions are dead flesh and bones animated by necromancers using the power of death. Minions follow the caster with the exception of the wurm. Once summoned, the minion will automatically attack hostile targets, can be influenced using a corresponding sequence skill, and can be resummoned without a corpse if destroyed. Necromancers can create up to six different minions, depending on their build.
- Gyros are mechanical automatons (similar to, but distinct from, the asuran golems) created by the scrapper elite specialization available to engineers. Little is currently known about them, save that they have a limited duration and can be detonated (like turrets), whilst also granting special tool belt skills based on their purpose.

- In the Reddit Guild Wars 2 developers AMA of 14 December 2011, Jonathan Sharp misspoke about elementalists having access to familiars. This was subsequently corrected, but did not rule out summons via elementalist skills as a possibility.
