Dragonmark Channel

This brooch is embedded with a small Siberys dragonshard, usually depicting the crest of its dragonmarked house. Each Dragonmark Channel is tied to a specific dragonmark, such as the Mark of Healing or the Mark of Making, and you can only attune to it if you possess that dragonmark.
While wearing a Dragonmark Channel, you can use it to cast any level 1 spell on your Spells of the Mark list. Once you use the channel, it can't be used again until you finish a Long Rest. Your spellcasting ability for this spell is the same as the spellcasting ability for the spells you can cast with your Dragonmark feat.
