Infuser guide
Updated
Board game: Infuser is Astral, or Moon and Star, in the official FAQ. The class-specific questions below are folded for players who have already opened its box.
How this class enters a campaign
Open the class box when your campaign explicitly instructs you. Retirement is not a universal class-unlock recipe. See the unlock guide for verified rules and missing individual prerequisites.
Builds
Editorial recommendation: coordinate shared resources with your party before choosing an opening sequence. Review the infusion rulings below, item timing, and solo restrictions. No item or leveling path is presented as a tested best build.
Questions
Astral spoilers: how do infusions work?
Pay elements when playing an infusion. Its persistent bonus remains active; its on-infusion trigger resolves immediately and when another infusion is played. Paying its elements again on a later turn does not replay the trigger.
Astral spoilers: what sequence and summon limits matter?
FAQ 8.7 illustrates Boon of the Tempest followed by Caress of the Night: active bonuses can improve later triggers. Animated Claymore receives persistent infusion benefits, not infusion triggers. Editorial recommendation: plan the element supply before committing both cards.
