The main body of an adult grick was about 6 ft (1.8 m) long. Including the length of the tentacles, this made a grick about 8 ft (2.4 m) long. A grick's head featured a pair of tiny eyes and a snapping beak surrounded by large barbed tentacles. The tentacles would cover the beak unless the grick was attacking or eating.
Gricks were adept at climbing and could slither up walls with little difficulty. Although they prefer to stay underground or indoors, gricks would venture into the open if food was scarce. Even then, gricks would only do so at night to avoid burning their small and sensitive eyes.
Gricks preferred to hunt in packs but could also be found hunting alone. Gricks hunted by waiting in busy areas and ambushing their prey. Gricks used their natural camoflage to remain hidden in rocky terrain.
If hunting in a pack, gricks would manoeuvre to outflank their pray wherever possible.. Due to their relatively small beaks, gricks could only take small bites of food. As a result gricks preferred to drag prey back to their nest once it was unconscious or dead.
Gricks laid oblong blue/green eggs about the size of a human fist. Young gricks were known as grick wormlings. Grick wormlings were edible and were known to be served in the Dalelands stuffed with rice pilaf and diced celery. Cured and spiced grick tentacles were also eaten.
Due to the grick's constant need to eat, some explorers consider the best way to kill a grick is to seal it inside its nest and wait for it to starve to death.
One of the circle of fangs rings was found on a chain around the neck of a drowned grick.
- Pages 30‒31 of Lost Mine of Phandelver describe the eruption of Mount Hotenow (1451 DR) as occurring "30 years ago", which would place the adventure in 1481 DR. However, pages 103 and 179 of Acquisitions Incorporated, a later source, state that the events described in the adventure happen five years after both Lost Mine of Phandelver and Princes of the Apocalypse. Since the latter is explicitly set in 1491 DR, and considering this answer by Ed Greenwood about dating the adventure, this wiki will use 1491 DR for events related to this sourcebook.
