Almudron

This creature usually keeps to itself deep in the mountains, but recently it has been approaching human habitation and attacking hunters, perhaps because of the Rampage.
It's adept at using mud to attack, and even defends itself by sticking it on its body.
From its tail oozes a strange golden fluid, which it uses to dissolve the ground beneath its prey, arresting them in a mire so that it can drag them under.
