As two actions, 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 weapon it wields which is emblazoned with the symbol of your deity. The weapon is a weapon associated with your deity (as St. Cuthbert is known for his mace and Thor for his hammer).
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 2d10 bludgeoning, piercing, or slashing damage on a failed save (based on the weapon associated with your deity), or half as much damage on a successful one. The guardian vanishes when it has dealt a total of 50 damage.
You can increase the damage by 1d10 and the maximum damage increased by 50 for each additional mana or psi expended.
