Greater Aberrant Mark

Your aberrant mark has increased in size and power. You gain the following benefits:

• Increase your Constitution score by 1, to a maximum of 20.
• Choose a 2nd-level spell and a 3rd-level spell from the sorcerer spell list. You learn these spells and can cast them through your mark. Once you cast a spell in this way, 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 2nd or 3rd level spell through your mark, you can expend one of your Hit Dice and roll it. If you roll an even number, you gain a number of temporary hit points equal to the number rolled. If you roll an odd number, one random creature within 30 feet of you (not including you) takes force damage equal to the number rolled. If no other creatures are in range, you take the damage.
