Combos, also called skill combinations, happen when skills interact with each other to create an additional effect. A skill must be a combo field or a combo finisher to be combined, which is an effect that is included in the skill description. For a combo to occur a combo field skill is used creating an area effect and then one or more combo finishers can interact with the field to create a combo. The largest number of combos are available through two characters of different professions working together but combos can also be created with two of the same profession or a single character.
- The combo field or initiator is a skill that creates an area effect of a particular type. The type is a recognizable element or characteristic which determines the effect they cause on a finisher; for example, a Flamewall will allow some eligible finishers to inflict burning. The relevant skills will interact so long as the finisher passes through the combo field at any point; for example, a projectile finisher will combo with a field so long as it passes through the field on the way to the target.
- The combo finisher is a skill which causes movement through or within the initiator's field such as creating a projectile or spinning or performing a leap. An eligible initiator augments the finisher by adding damage or creating other effects. For example, using Cyclone Axe near a Flamewall throws fire projectiles in different directions. Finishers can only interact with one initiator at a time. The finisher will trigger on the oldest initiator; a blast finisher will give Might instead of Healing if a water field overlaps an existing fire field.
Whenever a combo is created, a notification will show on the player's screen, indicating the effect that was generated by the combo.
 Combo effects
The four types of finishers each apply their effects differently:
- Blast finishers apply their effect to all foes or allies in the area where the blast occurred with radius 360.
- Leap finishers apply their effect either to the target foe or to yourself.
- Projectile finishers apply their effect either to the target foe or to allies adjacent to the target.
- Whirl finishers cause multiple projectiles to be launched in random directions.
When applicable, the stats of the character that activated the finisher are used to calculate the combo effects. This is most relevant to combos that inflict damaging conditions, as well as the healing effects of water fields.
|Field||Professions||Blast finisher||Leap finisher||Projectile finisher||Whirl finisher|
|Dark||Area Blindness||Blindness||Life stealing||Leeching Bolts|
|Ethereal||Area Chaos Armor (3 s)||Chaos Armor (5 s)||Confusion (5 s)||Confounding Bolts (5 s)|
|Fire||Area Might (x3, 20 s)||Fire Armor||Burning (1 s)||Burning Bolts|
|Ice||Area Frost Armor||Frost Armor||Chilled||Chilling Bolts|
|Light||Area Retaliation (3 s)||Retaliation (5 s)||Remove Condition||Cleansing Bolts|
|Lightning||Area Swiftness (10 s)||Dazing Strike||Vulnerability (x2, 5 s)||Brutal Bolts|
|Poison||Area Weakness (5 s)||Weakness (8 s)||Poison (2 s)||Poison Bolts|
|Smoke||Area Stealth (3 s)||Stealth (3 s)||Blindness||Blinding Bolts|
|Water||Area Healing||Healing||Regeneration (2 s)||Healing Bolts|
Some projectile finishers (most skills in the first slot of the skill bar as well as multiple projectile skills) only grant a 20% chance of applying the effect for each projectile; this is usually noted on the tooltip for the skill.
