In the Wight thread I propose this.
life drain should be replaced with exhaustion.
wight
Constitution Saving Throw: DC 13, one creature within 5 feet.
Failure: 6 (1d8 + 2) Necrotic damage, and gain a level of exhaustion
vampire
Bite (Bat or Vampire Form Only). Constitution Saving Throw: DC 17, one creature within 5 feet that is willing or that has the
Grappled,
Incapacitated, or
Restrained condition.
Failure: 6 (1d4 + 4) Piercing damage plus 13 (3d8) Necrotic damage. and gain 2 levels of exhaustion. .
So what monsters should exhaustion damage, and we are using the 2024 exhaustion.
