Homebrew:Infusion: Armor of Emergencies

(OOC: This is an implementation of the Armor of Emergencies infusion from Tasha's Crucible of Everything Else volume 2)

Prerequisite: 6th-level Artificer

Item: a suit of armor (requires attunement)

When you finish a short or long rest, you can cast a cantrip or a spell of 1st level with a casting time of 1 action, and describe a circumstance. For example, you could set up the armor to cast cure wounds on the person wearing this armor when they are reduced to zero hit points. The spell takes effect when the circumstance you described is met, rather than when you cast it. The spell can only affect the person wearing and attuned to this item, even if it can normally target others. Once the spell is cast, the armor loses this ability until the next dawn.
