Mace

Melee Weapon Attack: +3 to hit, reach 5 ft., one target. Hit: 4 (1d6 + 1) 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.

Sacred Flame (Cantrip; V, S)

One creature the priest can see within 60 feet makes a DC 13 Dexterity saving throw taking 9 (2d8) radiant damage on a failure. This spell ignores cover.

Guiding Bolt (1st-Level; V, S)

Ranged Spell Attack: +5 to hit, range 120 ft., one target. Hit: 14 (4d6) radiant damage and the next attack roll made against the target before the end of the priests next turn has advantage.

Dispel Magic (3rd-Level; V, S)

The priest scours the magic from one creature object or magical effect within 120 feet that they can see. A spell ends if it was cast with a 3rd-level or lower spell slot. For spells using a 4th-level or higher spell slot the priest makes a Wisdom ability check (DC 10 + the spells level) for each one ending the effect on a success.

Spirit Guardians (3rd-Level; V, S, M, Concentration)

Spectral forms surround the priest in a 10-foot radius for 10 minutes. The priest can choose creatures they can see to be unaffected by the spell. Other creatures treat the area as difficult terrain and when a creature enters the area for the first time on a turn or starts its turn there it makes a DC 13 Wisdom saving throw taking 10 (3d6) radiant or necrotic damage (priests choice) on a failure or half damage on a success.
