Aberrant Dragonmark

You have manifested an aberrant dragonmark. Determine its appearance and the flaw associated with it. You gain the following benefits:

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 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 develop a random flaw from the Aberrant Dragonmark Flaws table.

Option: Greater Aberrant Powers

At the DM's option, a character who has the Aberrant Dragonmark feat has a chance of manifesting greater power. Upon reaching 10th level, such a character has a 10 chance of gaining an Epic Boon from among the options in chapter 7 of the Dungeon Master's Guide. If the character fails to gain a boon, they have a 10 chance the next time they gain a level.

If the character gains a boon, the DM chooses it or determines it randomly. The character also permanently loses one of their Hit Dice, and their hit point maximum is reduced by an amount equal to a roll of that die plus their Constitution modifier (minimum reduction of 1). This reduction can't be reversed by any means.
