They could uniquely disgorge lava out from their claws.
Magma claws preferred to ambush they prey, hiding in plain sight by posing as mere hunks of volcanic rock. When they felt their opportunity had come a magma claw would rush towards their prey and immobilize it by pouring out sticky lava around its legs. They would then attempt to bludgeon their prey to death with their fiery claws.
Following the Spellplague, many magma claws made their way through elemental vortices and planar rifts into volcanic regions of Toril's and the Underdark. In 1479 DR, magma claws could be found inhabiting Mount Hotenow.
Magma claws could subsist on merely clay, ores, and even minor elementals. Though they preferred to hunt and feast upon organic creatures, savoring the taste of burned flesh. Whenever they killed a humanoid they would devour them whole, including their equipment.
Magma claws were occasionally bullied by magma brutes and magma hurlers into fighting alongside them. They were also often lured into serving fire archons, fire giants, salamanders, and even the occasional eye of flame.
