This is a homebrew review request for the "dying"-condition, but the different exhaustion plays a part in that.
Exhaustion: There are 10 levels of exhaustion, each level of exhaustion a character has gives a stacking -1 penalty to all of their D20 rolls(So at level 1 you get -1, at level 5 you get -5 etc.). At exhaustion level 10 the character dies. A short Rest recovers 2 levels of exhaustion, a long Rest recovers 5 levels of exhaustion.
Dying: A Character that gets knocked down to 0 HP is now considered dying. A dying character is prone and cannot stand up. At the start of their turn, a dying character loses concentration and has to make a death saving throw. A dying character can perform one action, one bonusaction or take their movement. Taking an action while dying inflicts 3 levels of exhaustion, taking a bonusaction inflicts 2 levels of exhaustion. Taking your movement while dying does not inflict exhaustion. A dying character can not take reactions and therefor can not ready an action.
My goal is to give a dying character something meaningful to do other than rolling death saves and waiting to be healed/stabilized or die.
What do you think?
