    Cast while Channelling Support

    Cast while Channelling Support is a Support gem that trigger linked non-channeling Spell while the character is using a channelling skill.

    Skill functions and interactions

    • Triggered Spell Priority: Cast while Channelling follows the same restrictions as other trigger support gems such as Cast On Critical Strike Support, in that only one spell can be triggered per event. If multiple Spells are linked, the spells will cycle based on the order in which they are socketed.

    • Casting Interval: Unlike Cast On Critical Strike Support, the listed interval is not a cooldown. Cast while Channelling casts the trigger spell exactly on the listed interval regardless of the cast time of the channeled spell.

    • Spell Totem Support: Cast while Channelling cannot support a skill gem that is supported by Spell Totem Support gem.
