Godmark

You have manifested a Godmark. The DM determines its appearance.You gain the following benefits:

• You learn a cantrip of your choice from the sorcerer spell list. In addition, you gain the Shield spell. 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.
• Your Dirty may also cast the Shield spell through your mark at its discretion. When this happens roll a Hit Dice, the number rolls is subtracted from your Hit Point Maximum until 2 changes of the tides have passed.
