Lesser Aberrant Dragonmark

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

• Increase a score of your choice by 1, to a maximum of 20.
• You gain the active ability Dragon Fervor. Once active, your attacks gain a +1 to hit or +1 spell attack, and an addittional 3d6 to attacks or 3d6 force damage to magical attacks.
• You gain 3d10+ tour constitution modifier of temporary hit points for the duration of Dragon Fervor.

Dragon Fervor lasts for 10 minutes.

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 percent chance of gaining an epic boon from among the options in chapter 7 of the Dungeon's Master Guide. If the character fails to gain a boon, they have a 10 percent 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.
