Mace

Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 5 (1d6 + 2) bludgeoning damage. On a hit the priest can expend a spell slot to deal 7 (2d6) radiant damage plus an extra 3 (1d6) radiant damage for each level of the spell slot expended above 1st.

Web (2nd-Level; V, S, M, Concentration)

Thick sticky webs fill a 20-foot cube within 60 feet lightly obscuring it and making it difficult terrain. The webs must either be anchored between two solid masses (such as walls) or layered 5 feet deep over a flat surface. Each creature that starts its turn in the webs or that enters them during its turn makes a DC 15 Dexterity saving throw. On a failure it is restrained. A creature can escape by making a DC 15 Strength check. Any 5-foot cube of webs exposed to fire burns away in 1 round dealing 5 (2d4) fire damage to any creature that starts its turn in the fire. The webs remain for 1 hour.

Guardian of Faith (4th-Level; V)

A Large indistinct spectral guardian appears in an unoccupied space within 30 feet and remains for 8 hours. Creatures of the priests choice that move to a space within 10 feet of the guardian for the first time on a turn make a DC 15 Dexterity saving throw taking 20 radiant or necrotic damage (high priests choice) on a failed save or half damage on a success. The spell ends when the guardian has dealt 60 total damage.

Insect Plague (5th-Level; V, S, M, Concentration)

A 20-foot-radius sphere of biting and stinging insects appears centered on a point the priest can see within 300 feet and remains for 10 minutes. The cloud spreads around corners and the area is lightly obscured and difficult terrain. Each creature in the area when the cloud appears and each creature that enters it for the first time on a turn or ends its turn there makes a DC 15 Constitution saving throw taking 22 (4d10) piercing damage on a failed save or half damage on a success. The priest is immune to this damage.
