Due to a player shortage tonight I had to quickly roll a healer. Due to time I let the DM do most of it for me as I'm still pretty new. I did the naming and rolled for my stats but I let him pick my spells and cantrips. One that he gave me is Spare the Dying.
Now that we're done playing I'm reading up on the spells and even class to see if I want to change anything should I need to play the Healer again. Some websites say Spare the Dying makes no sense when you can just use Healer's Kit.
In the PHB on page 151 the Healer's Kit reads:
This kit is a leather pouch containing bandages, salves, and splints. The kit has ten uses. As an action, you can expend one use of the kit to stabilize a creature that has 0 hit points, without needing to make a Wisdom (Medicine) check.
That last clause, without needing to make a Wisdom (Medicine) check, is interesting to me. It seems to imply if you are proficient in Medicine there is a way to stabilize someone without the kit. I did become proficient in Medicine and History. Is there a way for me to stabilize without using the Healer's Kit? If not, then what is the point in the clause about Medicine check?
