Infusion

Some Skills create Elemental Infusion Remnants when specific conditions are met. Picking up the Remnant grants you the Infusion for 20 seconds or until it is Consumed by another Skill. You can have up to 3 of each Infusion by default.

Skills that can Consume Infusions specifically mention the type(s) of Infusion they can Consume and the benefits for doing so. If a Skill repeats or reoccurs, each of them must Consume an Infusion separately to gain the effect.

Infusions are a stackable buffs which can be consumed by certain spells to gain additional effects. They are generated as remnants that spawn from certain skills.

Mechanics

There are three different types of Infusions, one for each element: Fire Infusion, Cold Infusion, and Lightning Infusion.

Elemental Equilibrium randomizes the element type of Elemental Infusions generated.

Refracted Infusion gives a 50% chance to gain an additional Infusion each time you collect one.

Scouring Winds creates a copy of any remnants after a 3 second delay.

Skills that create remnants

Snap generates a remnant based on any ailments on enemies caught in the explosion.
Living Bomb creates Fire when it explodes.
Frost Bomb creates Cold after explosion.

Version history

Version	Changes
0.3.0	Added a new mechanic called Elemental Infusion that many Elemental Spells interact with. Some skills create Infusions of a specific element as Remnants on the ground, which can be picked up to grant you the Infusion. Other skills can consume Infusions of a specific type to grant additional bonuses depending on the skill. Some skills consume infusions that match the skill's elemental type, while others have cross-elemental infusions. The Lightning/Cold/Fire/Chaos Infusion Support Gems have been renamed to Lightning/Cold/Fire/Chaos Attunement. The following have been renamed to avoid confusion with the new Elemental Infusion mechanic: Amazon's Infuse Weapon Skill has been renamed to Elemental Surge. Spire of Ire's Chaotic Infusion Unique Skill has been renamed to Chaotic Surge. The Charge Infusion Skill has been renamed to Charge Regulation.
