An Aghlorv resembles a six-legged, hairless cat with scaly skin and two rows of barbed spines running down its back. Its skin is often a dull amber, and its eyes are generally a deep hazel. Although an aghlorv prefers to crawl on all six legs, it is able to move comfortably on only four (freeing its front paws for attacking) and can move at a reduced rate on its two hind legs, enabling it to attack with the four upper paws. When attacking bipedally, on a successful hit an aghlorv may hold its target with two of its attacking arms; this will give the target the grappled condition and reduce the number of attacks available to the aghlorv to only one claw per round (as long as the hold lasts). Additionally, it is able to climb reasonable terrain easily due to its number of arms and claws.

An aghlorv is highly feared due to its quick speed and ability to move silently. Most commonly, an aghlorv will stalk its prey silently and surprise or else lie in wait, hidden, and spring out to attack at the most opportune time. Because of its lithe and agile nature, it is exceptionally difficult to notice an aghlorv before it is upon you, and even harder to surprise one due to its keen sense of hearing. As such, any creature that encounters an aghlorv has their surprise roll range increased by 2 to all surprise rolls, and any surprise rolls towards the aghlorv has its range reduced by 2 (a minimum of 1).
