Ropers inhabit subterranean caverns. They prey upon all forms of
creatures, but humans are their favorite form of food.

Body Mutability: These monsters can
stand upright in order to resemble a pillar or stalagmite or flatten
themselves at full length upon the floor so as to look like nothing more
than a hump.

6 Strands: The roper has six strands of strong, sticky rope-like excretion which it can
shoot from 2”-5”. A hit causes weakness (50% from strength in 1-3 melee
rounds), and the roper then draws its prey into its toothy maw where it is
quickly devoured. The chance for breaking a strand is the same for
opening a door, but every round the roper will drag the victim 10’ closer.

They are unaffected by lightning, take half damage at most from cold, but
are very susceptible to fire (-4 on saving throw).

The roper has a gizzard-like organ which holds 3-18 platinum pieces and can contain 5-20 gems (35% chance).

Description: This yellowish-gray monster appears to be a mass of foul, festering corruption.
The roper is cigar-shaped, about 9’ long, with a diameter of some 3’.

Half-grown roper: AC 3; MV 3”; HD 5;
hp 25; #AT 1; D 2-12; SA 6 sticky strands
that cause weakness; SD 45% magic
resistance, immune to lightning, takes
only 1/2 damage from cold (A4)

Umber hulks.
 

Ah well, that's another original I created, as are ropers and shambling mounds, the latter inspired by The Heao from the old Airboy comics I loved dearly as a lad.

Something similar could be done, with a different name and appearance and modes of attack and defense, but that rather contradicts the purpose,

Cheers,
Gary

The Roper I dreamed up out of whole cloth, like the unber hulk, so WotC could well claim it is unique.
They missed quite a few others that I made up from whole cloth, of course.
