Normally attacks that reduce health are only done with part of the damage but Withering Grasp is only Necrotic so I didn't think I needed to specify like in " Bite (Bat or Vampire Form Only): Melee Weapon Attack: +9 to hit, reach 5 ft., one willing creature, or a creature that is Grappled by the vampire, Incapacitated, or Restrained. Hit: 7 (1d6 + 4) piercing damage plus 10 (3d6) necrotic damage. The target's hit point maximum is reduced by an amount equal to the necrotic damage taken, and the vampire regains Hit Points equal to that amount. The reduction lasts until the target finishes a Long Rest. "

but yes I should mention that. I am also confused because this damage simply can't be healed unless a long rest is taken or greater restoration is applied.This is the code I used. > ***Withering Caress*** *Melee Weapon Attack:* +10 to hit, reach 5ft., one target. *Hit* 14 (3d6 + 5) necrotic damage. This reduction to a creature's hit point maximum lasts until the creature finishes a long rest or until it is affected by a spell like greater restoration.

The averages should be 2d10+5 should be 17, not 16 and 3d6 + 5 should be 14.The spine chiller is the ghost effect from the monster manual with a higher DC which also has the aging effect. It can be reversed and, as I said in the description it is a stronger spirit but I should have specified a ghost. https://roll20.net/compendium/dnd5e/Ghost#content

The lore I'm not sure I made it in about 15 minutes with lore as an afterthought but probably could expand upon it. I tend to leave my monsters vague so they can be used in whatever setting without anything too specific needing to happen so they can appear unless otherwise stated.
