I wanted to be a healing and death to be a little more gritty than standard 5th Edition. I also wanted falling unconscious to be more dangerous and the possibility of instant death more likely. My desire was to removes some of the pop-tart effect of constantly letting the fighters drop to 0 hit points only to spring back up 6 seconds later. The healers should be doing their jobs before the front line falls unconscious.
When considering the changes, I thought the 7-day long rest variant as outlined in the Dungeon Master's Guide was overdoing it. While want healing magic to become a more important resource to be managed, I did not wish to alter other long rest recharge powers. In that vein, I wrote up a slower healing variant for B/X-5, my own home brew homage to Old School D&D. I think this modification strikes a balance between seemingly fast default healing and overly slow variants I've seen. Healing works essentially the same as in 5th Edition with some minor changes highlighted below.
