Ghoul Touch (5e Spell)
From D&D Wiki
|Casting time:||1 action|
|Components:||V, S, M (a small scrap of cloth, wrapped around your hand when you touch the target)|
|Duration:||Concentration, up to 1 minute|
You touch a living creature to imbue a minor magical strain of undeath, paralyzing it. The target must succeed on a Constitution saving throw or become paralyzed for the spell's duration. Constructs and undead automatically succeed on this saving throw.
A creature paralyzed with this spell exudes a terrible stench that effectively nauseates all other creature within proximity. During the spell's duration, when a creature first enters or starts its turn within 5 feet of the paralyzed creature, it must succeed on a Constitution saving throw or become poisoned until the start of its next turn. Constructs and undead automatically succeed on this saving throw.
