Brand of the Blood Hunter

You have endured the Hunter's Bane. To mark your initiation, you have been branded with the sigil of the Blood Hunters. You gain the following benefits:

• Increase your Constitution score by 1, to a maximum of 20.
• You learn a cantrip of your choice from the sorcerer spell list. In addition, choose a 1st-level spell from the sorcerer spell list. You learn that spell and can cast it through your brand. Once you cast it, you must finish a short or long rest before you can cast it again through the brand. Constitution is your spellcasting ability for these spells.
• When you cast the 1st-level spell through your brand, 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 necrotic damage equal to the number rolled. If no other creatures are in range, you take the damage.
