Aberrant Dragonmark (WGE)

Wayfinder's Guide to Eberron p. 112

Description

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

You learn a cantrip 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 at its lowest level. Once you cast it, you must finish a long rest before you can cast it again. Constitution is your spellcasting ability for these spells.

You can increase the power of your aberrant spells at the risk of your own vitality. When you cast a spell with your aberrant mark, you can use one of your Hit Dice to increase the spell's level by 1. Immediately after you cast the spell, roll the Hit Die. You take damage equal to the number rolled.

You also develop a random flaw from the Aberrant Dragonmark Flaws table.
