Command Elemental (Stone Sage)

Using powers of elemental energy, you can command elemental creatures, making them into your servants.
Prerequisites: Channel energy class feature and Elemental Channel feat, or the stone sage dwarven racial archetype.

Benefit: As a standard action, you can use one of your uses of channel energy to enslave elementals within 30 feet. Elementals receive a Will
save to negate the effect. The DC for this Will save is equal to 10 + 1/2 your cleric (or stone sage) level + your Charisma modifier. Elementals that fail their saves fall under your control, obeying your commands to the best of their ability, as if under the effects of control undead. Intelligent elementals receive a new saving throw each day to resist your command. You can control any number of elementals, so long as their total Hit Dice do not exceed your cleric level. If you use channel energy in this way, it has no other effect (it does not heal or harm nearby creatures). If an elemental creature is under the control of another creature, you must make an opposed Charisma check whenever your orders conflict. You can only command elementals of the same subtype chosen for the Elemental Channel feat.

Special: If you have the stone sage dwarven racial archetype, you can command earth elementals a number of times per day equal to 3 + your Wisdom modifier. A stone sage does not have the channel energy ability.
