D&D 5.5e Monster Manual
Poison
Varies
Creatures whos wounds are exposed to this venom by a creature, object, or weapon must succeed on a DC 11 Constitution Saving Throw, or have the poisoned condition for 1 minute. While poisoned in this way the effected creature is paralyzed.
Effected creatures can repeat the save for this venom at the end of each of it's turns, ending the effect on a success, otherwise they automatically succeed at the end of 1 minute.
Thick and slimy Venom strings like mucus within this glass bottle. Turning the bottle any which way seams to just barely move the Venom of a Grell.
