Description
Blazing arachnids are ambush predators, stalking their prey either on the Elemental Plane of Fire or near volcanoes and lava flows on the Material Plane. Peeking up from lava flows, their eight red eyes glow with lethal intelligence as they observe their prey waiting for the opportune moment to strike. These elemental spiders prefer to attack with their web first, entangling their opponent in the sticky flaming strands before they leap on their opponent and inject their victim with a venom that roasts their victim from the inside out. Unlike typical spiders who prefer their prey still living, the blazing arachnid prefer to consume the charred remains of their victims.
