Greater Dragonmark, Variant (Detection)

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

• The die type of your dragonmarked Intuition Die increases by one (from d4 to d6, for instance).
• Increase your Charisma 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.
