Earth Mastery (Ex): This thomil gains a +1 bonus on attack and damage if both it and its foe touch the ground. If an opponent is airborne or waterborne, the elemental takes a -4 penalty on attack and damage.

Engulf (Ex): For this thomil, the Reflex save DC to avoid the engulf attack is 17. The thomil can attempt to engulf Small or smaller opponents. See the template description for more information.

Push (Ex): This thomil can start a bull rush maneuver without provoking an attack of opportunity. The combat modifiers granted by earth mastery also apply to the thomil's opposed Strength checks.

The sample thomil uses a medium earth elemental as the base creature.

Earth Subtype

This subtype usually is used for elementals and outsiders with a connection to the Elemental Plane of Earth. Earth creatures usually have burrow speeds, and most earth creatures can burrow through solid rock.

Native Subtype

A subtype applied only to outsiders. These creatures have mortal ancestors or a strong connection to the Material Plane and can be raised, reincarnated, or resurrected just as other living creatures can be. Creatures with this subtype are native to the Material Plane (hence the subtype's name).

Unlike true outsiders, native outsiders need to eat and sleep.
