Greater Mark of Handling
Source: Eberron: Forge of the Artificer p. 43
Prerequisite: 4th
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 dice:1d6|noform|noparens|avg (1d6) instead of dice:1d4|noform|noparens|avg (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.
