Tentacles were an enemy class encountered by Raziel in Legacy of Kain: Defiance. They were a unique creatures that were apparently associated with the Elder God that rose from the ground to strike and grab and could be found in a variety of locations in the events of Blood Omen.
Each individual enemy appeared as a single human sized tentacle above ground with the 'body' of a tentacle covered in a sickly green gnarled skin through which bony barbs poked through, and a number of eyes could be found along each tentacle. Their extremities had a tridactyl claw made out of the same bony material as the barbs which they used to rake at their prey. They didn't appear to have souls of their own, though they did bleed regular Red blood[Defiance][Defiance/2][Defiance strategy guide]
Tentacles spent most of their time underground but could easily burrow through the ground - leaving a distinctive digging pattern on the surface - before bursting upwards into the air to catch and swipe at their prey with their claws and barbs. Primarily attacking through claw strikes and slaps, another tactic they used was to burst up as normal, then wrap their 'bodies' around the victim and both crush them and lacerate flesh with their barbs in a special attack dubbed Tentacle Grab. They seemed to detect movement through the vibrations of their prey on the surface.[Defiance][Defiance/2][Defiance strategy guide]
These cross-planar creatures are one of the many extraplanar beings that have found their way slowly into Nosgoth as the pillars have decayed. Normally they reside within the spectral realm, however the weakened boundaries between dimensions have allowed them to enter into the material world. Normally resting hidden beneath the ground they wait patiently for a helpless victim to wander by unbeknownst of their presence.
Special Attacks • Tentacle Grab: The tentacles are able on a successful hit to wrap around Raziel or Kain and use their massive strength to hold them vulnerable in place. These grasping arms can slowly drain your health so rapidly tap attack to escape.
Strategy If you are caught in its deadly grasp, hit attack to break free quickly. These are nuisance enemies that generally cause more trouble than harm. Walk in a circle to entice the limbs to appear and then sever them quickly.
The Tentacles are not directly named in game however they are identified as such in manuals and the official guide - which also names their special attack.[Defiance manual][Defiance strategy guide] Tentacles are listed as "tentacle" and "s_tentacle" in game files.[Defiance]
Although visually the Tentacles appeared to be a part of the Elder God, they were in fact quite separate creatures although they were associated with it - this is implied by their descriptions in official sources as "minions of the Elder God" and evidenced by their different color blood. The full size and appearance of the individual tentacles is ultimately unknown as the Tentacles are only seen from above ground.[Defiance strategy guide][Defiance manual][Defiance]
The summoning of Tentacles by the Original Nature Guardian suggests that the tentacles were natural creatures like other Animals. Their summoning and attacks in the battle against the Nature Guardian was given its own special attack title - Nature's Grip. Theoretically, since she could animate plants and change other natural creatures, the spirit of the first vampire nature guardian could have originally created them to help protect the fire forge.[Defiance][Defiance/6]
