Earth Glide (Ex)
An elder magma elemental can burrow through stone, dirt, lava, or any other kind of earth except metal like a fish swims through water. This leaves no trace or tunnel. The area feels warm for 1 round after its passing and often retains a smooth feel as if it had been polished.
Lava Puddle (Su)
Once per day, a magma elemental can extrude a puddle of lava as a full-round action, filling its space to a depth of 3 inches. This counts as difficult terrain. A creature that moves through the lava takes 2d6 points of fire damage. The damage continues for 1d3 after the creature leaves the lava, though these additional rounds only deal 1d6 damage. After 2 minutes, the lava solidifies and is safe to touch. At the GM’s discretion, while the lava is hot, it can start secondary fires.
Environment any (Plane of Fire)
Organization solitary, pair, or gang (3–8)
