As an action, a Large spectral guardian appears and hovers for the duration in an unoccupied space of your choice that you can see within 9 meters. The guardian occupies that space and is indistinct except for a gleaming sword and shield emblazoned with the symbol of your deity.
Any creature hostile to you that moves to a space within 3 meters of the guardian for the first time on a turn must succeed on a Reflex saving throw. The creature takes 3d6 radiant damage on a failed save, or half as much damage on a successful one. The guardian vanishes when it has dealt a total of 70 damage.
You can increase the damage by 2d6 and the maximum damage increased by 40 for each additional mana or psi expended.
