Mark of The Witch Fang of The Frunglywood (V2)

 Your soul has been sold to Molgarax and with it your skin branded with her mark. You gain the following benefit's from this mark:

• You learn a cantrip of your choice from the draconic sorcerer's spell list. In addition, choose a 1st-level spell from the sorcerer 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, 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.

You also gain the following drawbacks:

• Your cursed nature puts the natural world uneasy, your animal handling checks are made at disadvantage.
• You have horrific nightmares after you use your mark based around whatever is tormenting you most. These nightmares have a 25% chance of seeping into the minds of those around you.
