Dragonmark, Greater Mark of Handling

Most dragonmarks are small—no more than the size of the bearer's palm—and grant limited magical power. And even these minor marks are rather rare. But rarer and more powerful marks appear on some individuals, both within and outside the dragonmarked houses. Greater dragonmarks manifest only on people who already possess an ordinary mark. When a greater dragonmark manifests, it grows from an ordinary mark and expands outward to two or three times the original mark's size. The dragonmarked houses view greater marks as more significant than ordinary marks in every way—more important to the livelihood of the house, more essential to keep under the house's control, and potentially more significant in terms of fulfilling the Draconic Prophecy that some believe is written in the marks.

You gain the following benefits:

Ability Score Increase. Increase one ability score of your choice by 1, to a maximum of 20.

Improved Intuition. When you use the Wild Intuition benefit of your Mark of Handling feat, you can roll 1d6 instead of 1d4.

Improved Handling. While you are mounted, immediately after you hit a target within 5 feet of your mount with a melee attack roll, your mount can take a Reaction to move up to its Speed or take the Attack action to make one attack only (your choice).

Subdue Animal. As a Magic action, you exert command over one Beast or Monstrosity you can see within 30 feet of yourself. The target must succeed on a Wisdom saving throw (DC 8 plus your Wisdom modifier and Proficiency Bonus) or have the Frightened condition until the start of your next turn. You can use this benefit a number of times equal to your Proficiency Bonus, and you regain all expended uses when you finish a Long Rest.
