Trigger

Trigger effects causes a supported skill gem to activate when a specified condition is met, without spending its mana cost or requiring a cast animation. They have slightly different behaviour depending on whether they are an active gem or linked to a trigger gem or item.

Active and support trigger gems

• Active trigger skills (counter-attacks) will, when their condition is met, trigger an automatic melee attack to occur. This attack uses no mana and does not interrupt the players other actions. They do not require any supports to function, but any supports linked will apply to the melee attack. Active trigger skills can be supported by trigger support skills which require an attack skill as part of their triggering condition.

• Support trigger skills must be supporting a spell and will, when their condition is met, trigger the casting of that spell without requiring a cast animation or mana. Some support trigger skills must also be supporting a second active skill as the basis for their trigger condition. For example, must be linked to both an attack gem and a spell gem to function - When the attack crits, the spell will be cast. In this case, supports in the chain will support both the triggering attack and the triggered spell, if applicable to both. When an active skill is linked to a trigger effect, it cannot be cast by the player manually. Supported skills also have a 500ms cooldown between each trigger.

Interactions

Multiple trigger supports: A single attack skill cannot be supported by multiple trigger support gems or item - a chain which contains more than one trigger condition will cause active skills in the chain to be disabled.

Multiple triggered skills: Only one supported skill will be cast per trigger. The spell that is triggered is determined based on the order in which it is socketed, and will cast supported spells in sequence, even across multiple attacks. For example, a MjölnerMjölner

Traps and mines: Spells that are made into traps/mines by the use of the or gems cannot be triggered by any trigger effect but will still be disabled when linked to an applicable trigger gem. The Detonate Mines skill gem, however, can be linked to a trigger gem. Traps, mines, and totems also cannot trigger .

Cooldowns: Trigger effects cannot bypass cooldowns such as that of .

Targeting: Directional spells will cast towards the triggering enemy. If the enemy was killed by the triggering attack, it will cast towards the cursor or in a random direction.

Totems: It is not possible to summon any kind of totem using trigger gems. Totems can not trigger any further effects themself as well.

Vaal gems: Trigger effects cannot trigger vaal skill gems, even if the player has the required amount of souls.

Warcries: Since warcries are neither spells nor attacks, there are currently no trigger effects which interact with them.

Order

Generally the order in which skill gems are linked only holds importance for trigger gems and for rounding the mana cost. The order for sockets used is:

1	⇒	2
		⇓
4	⇐	3
⇓
5	⇒	6

If multiple trigger gems are socketed in several equipped items the order will be:

Main hand ⇒ Amulet ⇒ Helm ⇒ Off hand ⇒ Body armour ⇒ Gloves ⇒ Boots

Gems

There are several trigger gems present in the game. Some are offensive, some defensive, and some are counter-attacks:

Let the frigid air engulf your soul. Embrace the eternal cold, And it will embrace you back., only one skill can be triggered per trigger event. The damage of Cast on Critical Strike and Cast on Melee Kill has been increased, as described in "Active Skill Gem Balance" below. The spell that is triggered is determined based on the order in which it is socketed, and will cast supported spells in sequence, even across multiple attacks. These items and skills also have cooldowns which limit how often a skill is cast. These cooldowns apply per-triggered-skill, rather than applying to the trigger gem itself. All unique items that trigger skills, now and going forward, follow the rule that if a skill is triggered, it can only be used by that trigger and cannot be directly cast by the player as well. Previously, only the trigger support gems limited the use of the triggered skills this way, while skills triggered by unique item properties could be self-cast.

1.3.0	Added Reckoning, Riposte, and Vengeance (Counter-attacks) to the game.
1.2.2	We have restricted skills to only work with a single trigger gem at a time. Skills supported by multiple triggers will be disabled and won't work with any of them.
