DnD Sex Edition

Ropers are large tentacled monsters that camouflage themselves as stalactites (that hang “tite” to the ceiling) and ambush their prey. It is unlikely that a PC would know a roper is around and able to be seduced, but if the PC thinks these monsters are sexy, maybe they’ll just be attempting to seduce every stalactite or stalagmite they come across. Not kink shaming. They are pretty phallic looking. Ropers prefer to ambush their prey and may also enjoy congregating in small groups to debate pain and terror. 

You walk into the cavern. There has to be a roper in these caves somewhere you think. You’re momentarily distracted by thoughts of six tentacles caressing your body. Maybe four would be used for capturing your wrists and ankles while the remaining two explored your body… You forcibly focus your thoughts on the task at hand: attempting to seduce any willing looking stalactites. 

Make a DC 15 Performance check (or DC 10 for 5e since ropers are only CR 5 in that system).

On a success:The darkness of the cave ceiling is damn near opaque, even to your eyes. Still, you present what you know of roper seduction techniques and release the bottled pheromones you spent too much money on. A large sticky object comes sailing out of the darkness at startling speed, striking you in the face. 

PC takes 2d8 bludgeoning damage from the hit.

It feels as though you’ve been punched. You reach up and grasp the thing adhered to your cheek. It pulls away from your skin with a squelch, leaving behind a moist, tacky residue.  It’s long and thin, curving to a delicate bulbous end.

Make a DC 15 Knowledge Dungeoneering or Nature check.

• On a success: It’s a phallus. You’ve heard of creatures that can throw their phallus at potential mates. You just didn’t know ropers were one of them! You lift your prize in victory and immediately decide that you’ll leave the swiftly forming bruise on your face unhealed until it fades naturally over the next several days. It’s a badge of honor, after all.
• On a fail: It’s sticky and gross and that’s about all you know. You drop it to the cavern floor and proceed forward, slightly more alert for additional projectiles, but none come.

The PC passes through this cave unmolested by ropers.

On a fail: The darkness of the cave ceiling is damn near opaque, even to your eyes. Still, you present what you know of roper seduction techniques and release the bottled pheromones you spent too much money on. It smells off. Like it has rotted in the time since you purchased it from a fast talking salesman. You gag and your eyes water, causing you to miss the creature that drops from the ceiling to land on top of you. 

Roll for Initiative. The PC starts the combat with the roper grasping the PC and no weapons drawn. The PC must either make a DC 15 strength save to escape or a pass a DC 25 Fort save to avoid taking 1d6 Strength damage.
