Boon of Cartoony Camaraderie

Whenever a friendly creature other than yourself within 30 ft of you that you can see receives damage, you can use your reaction to give a quick motivational speech or invoke a flashback of your memories spent together and spend 2 of your hit dice to heal that creature for that amount.

However, if the chosen creature is currently at or reduced to 0 hit points, you instead spend 2 of your hit dice to grant a bonus equal to your proficiency bonus on their death saving throw until they become either stable or regain 1 hit point.

The chosen creature must be able to see or hear you to receive this benefit.

You can use this feature a number of times equal to half your level (rounded up) between long rests.
