At our table (where I DM) we do the following:Long Rest = One Hit Die + CON Mod of healing (so a Fighter with 14 CON would get 12 HP back), Hit Die Recovery as Normal.Being reduced to 0 HP = One level of Exhaustion and an Injury. The Injury you take reflects the amount of damage on the hit that reduced you to 0 HP.We feel the above makes non-rest healing (spells, potions, magic items, magic places, Healer feat, etc) much more valuable and getting hurt badly enough to be making Death Saves actually mean something. So far we have all really enjoyed the added tension and grittiness it adds without it feeling too arbitrary.Has anyone else done something similar and what were your results?
