I'm surprised this one has remained unconverted so long. I'm a huge fan of the under-utilized plane of Pandemonium, and fiends are my favorite monsters, so I guess I must've overlooked them as an ettercap knockoff based on the artwork.

The tener is a grey, hairy, spindly-limbed creature. It is bipedal and has long claws on the hands of its four arms. It has large amber eyes set in a small round head, and spiderlike chelicerae flank its fanged mouth. The tener is greed incarnate and will jealously guard anything of the slightest value. It regards all strangers as thieves, but it itself has all of the abilities of a 9th-level thief except for backstabbing capabilities.
Teners may use the following powers, one per round, at the 9th level of ability (where applicable): bestow curse reverse form of remove curse), darkness 15’ radius, detect invisibility, haste (self only), teleport without error (once per day), and slow (once per day). Teners have both infravision and ultravision. They are immune to poisons, noxious gases, and paralysis, and take half damage from fire and cold. Teners are harmed only by +1 or better weapons, and cannot be petrified or polymorphed.
The tener has a powerful grip. If it scores a hit with two of its hands, it holds its victim, striking at +3 “to hit” with its other two sets of claws and biting (at +3 “to hit”) for 1-2 points of damage. The bite of a tener is venomous and causes paralysis for 6-36 turns (save at -2). Individuals held by a tener attack at -3 “to hit”. A character’s chance of breaking a tener’s grasp is equal to his chance of bending bars, checked on any round that the attempt is made. No other action is possible for the character during such a round.
Teners are better known for their greed than for their malice, and they may be bribed not to harm a party. Such bribery is expensive, however, and not particularly reliable. Teners are native to the plane of Pandemonium and are also found, on occasion, in Limbo or the Abyss. They roam the Astral, Ethereal, and Prime Material Planes in search of treasure.
