Greater Dragonmark of Death

Prerequisite: 8th level, Character must possess a dragonmark
Your dragonmark has grown in size and power. This enhances your existing dragonmark, and the benefits are based on the mark that you already possess. A greater dragonmark provides the following benefits:
• Your Arcanist's Intiution die increases to a d6.
• Increase either your Intelligence or Charisma score by 1, to a maximum of 20.
• You learn the spells feign death and danse macabre, each of which you can cast once without expending a spell slot or using a material component. Charisma as your spellcasting ability for both. You regain the ability to do so when you finish a long rest.
