Greater Dragonmark, Variant (Warding)

Your dragonmark has grown in size and power. This enhances your Mark of Warding dragonmark, giving you additional benefits:

• The die type of your dragonmarked Intuition Die increases by one (from d4 to d6, for instance).
• Increase your Dexterity or Intelligence score by 1, to a maximum of 20.
• Choose a spell of 4th level or lower from your Spells of the Mark racial feature. You can cast this spell once per long rest without expending a spell slot or using material components*. Intelligence is your spellcasting ability for this spell.

*To cast Leomund's secret chest using this feat and the Mark of Warding, you must have a Siberys dragonshard with a value of at least 100 gp. While you have this dragonshard in hand, it serves as the spell's focus, and you can use it to summon and dismiss the chest.
