3 hours/mana
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 5 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).
When you cast this spell, you can designate any number of creatures you can see to be unaffected by it. A creature that moves within 1 meter of the spell’s area for the first time on a turn or starts its turn there must make a Reflex saving throw.
On a failure, it takes 2d12 bludgeoning, piercing, or slashing (based on the weapon associated with your deity) damage.
On a critical failure, it takes twice as much damage.
On a success, it takes half as much damage.
On a critical success, it takes no damage.
The guardian vanishes when it has dealt a total of 50 damage.
Augment
You can increase the damage by 1d10 and the maximum damage increased by 25 for each additional mana expended.
