Magma Elemental

A magma elemental’s slams deal half fire damage and half bludgeoning damage. In addition, on a critical hit, the fire elemental’s strikes deal an amount of burn damage based on the creature’s CR, as listed in the table below.

Once per day as a full action, a magma elemental can discharge a pool of lava that covers its space and spaces within its reach to a depth of 3 inches. Covered spaces are difficult terrain, and creatures that move through a space or that occupy a space at the time of the burst take fire damage and gain the burning condition. The fire damage equals that of the elemental’s slam and the condition deals the same amount as the elemental's burning strikes ability. An affected creature can attempt a Reflex save to halve the damage and negate the burning condition. The lava cools after a number of rounds equal to the elemental’s CR, causing the spaces to revert to normal terrain. At the GM’s discretion, this lava can start fires.
