Dragonmark Reservoir

Dragonmark Reservoirs are always embedded with a Siberys dragonshard, but come in many forms, most commonly an amulet or bracelet bearing the design of the house crest. Each reservoir 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.
A Dragonmark Reservoir has 7 charges. While wearing it, you can use it to cast any spell on your Spells of the Mark list at 1st or 2nd level, expending a number of charges equal to the level of the spell you cast. The reservoir regains 1d6 + 1 expended charges daily at dawn. Your spellcasting ability for this spell is the same as the spellcasting ability for the spells you can cast with your Dragonmark feat.
