Increase your Constitution score by 1, to a maximum of 20.
You have manifested an arcane mark. Determine its appearance and the flaw associated with it. You gain the following benefits:
- You learn a cantrip of your choice from the sorcerer or druid spell lists. In addition, choose a 1-st level spell from the same spell list. You learn that spell and can cast it through your mark. Once you cast it, you must finish a short or long rest before you can cast it again through the mark. Constitution is your spellcasting ability for these spells.
- When you cast the 1st-level spell through your mark, roll and expend one of your Hit Dice. If you roll an even number, gain a number of temporary hit points equal to the number rolled plus your Constitution modifier. If you roll an odd number, every creature in a 30 feet radius (including you) takes force damage equal to the number rolled.
You also develop a random effect from the Arcane Mark Effects table. The effect changes based on what spell list used when choosing the mark cantrip.
