As a full attack action, a Grick may use Tentacle Swarm to attack all creatures in a 10 x 10 foot square adjacent to its space. It rolls to hit once against each foe in the area of effect, and if it hits, it deals its normal tentacle strike damage, plus an additional of precision damage to each foe struck.
Weapon Sense (Su)
If any grick in a combat is damaged by a magical weapon that pierces its DR, all gricks in the combat know which of their enemies have that magic weapon and will target it if possible. If they cannot reach the foe with the magical weapon safely, they will fight normally. Multiple foes with magical weapons will be targeted as evenly as possible, and if there are more magical weapons than gricks, they will flee the battle if possible.

Grick
Gricks are wormlike alchemical abominations which were created eons ago by the same kind of madmen that thought owlbears and bulettes were a great idea. Gricks have a darkly mottled skin texture rather akin to a garden slug, but unlike a slug, a grick is the very paragon of rubbery durability. Even worse, Gricks can change their color, slowly, over the space of hours, to match the territory they inhabit.
Gricks have four sturdy tentacles at the front of their bodies, liberally equipped with rasping bone scutes and octopus-like suckers. These suckers extend to their pale bellies, as well. Mercifully, the suckers are of little use in combat, instead granting the horrible things a climb speed, and allowing them to drag prey with unnerving ease.
An adult grick is about 8 feet long from the tips of its tentacles to the end of its body and weighs some 200 pounds. Its body coloration is uniformly dark, with a pale underbelly, although the exact color varies with their habitat.
Although of animal intelligence, gricks are inherently and utterly evil, and will attack with cruel intent even when not hungry.
Optional Treasure Rules: Roll a d20 on Table 1 below once per encounter (NOT per creature). Any items discovered are in addition to the normal treasure for the encounter.
