I am currently trying the xp to level 3 unconscious rules and its going decently. I had to change it a bit, but it allows players to do actions even at 0 hp for a price. Hard to test since they are over level 12 and they are hard to hurt.
If you drink a healing potion outside of combat its full effect.
Bottled inspirations. They get one in their inventory if they still have one.
Present players play abseetees and get xp as a reward, so I dont redo encounters 10 minutes before the start.
