By means of this spell the caster draws upon the fury of Aya herself to lay waste to their enemies.  This spell causes massive spikes of earth to erupt in a 20 ft. burst from the caster, striking all enemies in the burst.  These spikes of earth affect only targetable enemies in the burst and does not affect allies as each target is attacked by the spell individually.  
The caster must roll a touch attack against each target in the burst that would be affected by the the spell for the attack to hit.  Those struck by the spell are dealt 1d6 earth damage per level to a maximum of 10d6.  Damaged targets are entitled to a Reflex saving throw for half damage.  Targets that take full damage from the spell however are subject to a Combat Maneuver check by the caster using their level to calculate the base attack bonus [same as high to-hit bonus] plus their pertinent caster stat [Wisdom, Intelligence, or Charisma] instead of their Strength score.  If the maneuver check passes, the target must roll a Fortitude saving throw.  A successful roll indicates that the target is staggered for one round while a failed roll indicates that the target is stunned for one round.  
The damage incurred by Aya's Strife counts as bludgeoning and piercing damage as if from an adamantium weapon for determining damage reduction effects.
