Mark of the Shadowfell

Your exposure to the Shadowfell’s magic has left a cursed mark on your body, granting you the following benefits.

Ability Score Increase. Increase your Intelligence, Wisdom, or Charisma score by 1, to a maximum of 20.

Shadow Magic. You always have the spells suggestion and mirror image prepared. You can cast each of these spells without expending a spell slot. Once you cast either spell in this way, you can’t cast that spell in this way again until you finish a Long Rest. You can also cast these spells using spell slots you have of the appropriate level. The spells’ spellcasting ability is the ability increased by this feat.
