Agares, Truth Betrayed
  
Agares died at the hands of his allies for a wrong he did not commit. As a vestige, not only does he give binders the ability to weaken foes and knock them prone, but he also makes his summoner fearless.

Vestige Level: 4th
Binding DC: 22
Special Requirement: You must draw Agares’s seal upon either the earth or an expanse of unworked stone.

Influence: Agares’s loyalty in life and his anger at the betrayal perpetrated by his lieutenants has become a hatred of falsehood. When influenced
by Agares, you speak forthrightly and with confidence. You cannot use the Bluff skill, and when asked a direct question, you must answer truthfully and directly.

Granted Abilities: 
Agares gives you the power to exalt yourself and your allies, to make the earth tremble beneath your feet, and to render foes weak.

Earthshaking Step: As a standard action, you can stomp on the ground, causing every creature within 10 feet of you to make a Reflex save or fall prone. 
Once you have used this ability, you cannot do so again for 5 rounds. You and your summoned earth elemental (see below) are never knocked prone by the use of this ability.
