You have the training and intuition to administer first aid and other care effectively, granting you the following benefits:

• If you have a Healer’s Kit, you can expend one use of it and tend to a creature within 5 feet of you as an Action. That creature can expend one of its Hit Dice and then roll that die. The creature regains a number of Hit Points equal to the roll plus your Proficiency Bonus.
• Whenever you roll a die to determine the number of Hit Points you restore with a spell, you can reroll the die if it rolls a 1, and you must use the new roll.
