[Monster] Creature from the Lower Planes

I like random monster generators, so today I'm trying a classic: the "Random generation of creatures from the Lower Planes" appendix that appears in the Dungeon Masters Guide. This two-page collection of tables is good for the generation of hybrid hellspawns of a Boschian quality. The results are monstrous, challenging, dangerous foes possibly with several attacks per round...

Behold...

The Essence Abductor 

Frequency: Uncommon
No. appearing: 1
Armor class: 0 (20)
Move: 6"
HD: 7
% in lair: N/A
Treasure type: N/A
No. of attacks: 1 mouth (2d4, only against a grappled target), 2 pincered hands (1d6+2), 1 grappling attack, with 4 extremely effective tentacle arms
Magic resistance: 35%
Intelligence: low
Alignment: Chaotic
Size: Large
Special attack/ability: Gate
Special defense: metal immunity
Strength: 18
To-hit: +1
Damage: +2

The Essence Abductor tears open space-time with its pincers (special ability: Gate), allowing it to appear unannounced in the worst possible moment.

The demon uses its tentacles to grapple the tastiest foe, then attaches its sucker-like mouth to drain the creature's essence.

Appearance:
Head: snake-like
Head adornment: ruff
Overall visage: wrinkled - seamed
Ears: trumpet-like
Eye color: metallic
Eyes: 2 small, multi-faceted eyes
Nose: tiny
Mouth: average, sucker-like
Body: quadrupedal et al.
Torso: bison-like
Body odor: sweaty
Skin: slimy
Predominant color: yellowish - tannish
Back: maned
Arms: 6 (2 human-like with pincered hands, 4 tentacles)
Legs and feet: suctioned


(lousy art by me)

This is a "slow" generator if you roll on every table, but the DM is encouraged to amend as needed. It's perfectly enough to, for example, just roll a body type, a head type, and HD on the fly.
