Make a melee spell attack on a creature within range. On a hit, that creature becomes afflicted with whichever magical disease your carrier has, and additionally takes 5d10 necrotic damage. If the creature is unaware of your presence, you can instead make a Sleight of Hand check to afflict them with this disease and damage, but symptoms will only begin showing after an additional 5 days. The DC of this skill check is equal to the target's passive perception.   The magical disease you inflict can only be countered by a remove curse spell of equal level to the slot level used to cast this spell. Additionally, you can choose to not deal any necrotic damage to the target creature.
