Wrath of the Kaiju, pg. 181
You are a member of the Heirs of Kirin, or have closely observed their ways and adopted their philosophy. You are adept at restoring others with healing kits, potions, and salves. You gain the following benefits
• Increase one ability score of your choice by 1, to a maximum of 20.
• You gain proficiency in the Medicine skill.
• You can drink a potion, or administer a potion to an ally, as a bonus action.
• When you use an object, such as a potion, and would normally roll one or more dice to restore hit points to a creature, you instead use the highest number possible for each die. For example, instead of restoring 2d4 + 2 hit points with a potion of healing, you restore 10.
