Valetta

As a bonus action, Valetta can expend a spell slot to cause her melee weapon attacks to magically deal an extra 10 (3d6) radiant damage to a target on a hit. This benefit lasts until the end of the turn. If Valetta expends a spell slot of 2nd level or higher, the extra damage increases by 1d6 for each level above 1st.

Valetta is a 5th-level spellcaster. Her spellcasting ability is Wisdom. Valetta has the following cleric spells prepared:

Cantrips (at will): light, sacred flame, thaumaturgy

Level 1 (4 slots): cure wounds, guiding bolt, sanctuary

Level 2 (3 slots): lesser restoration, spiritual weapon

Level 3 (2 slots): dispel magic, spirit guardians

Valetta can use her action to exhale a 5-foot-wide, 30-foot line of lightning (but can't do this again until she finishes a short or long rest); each creature in the line must make a DC 11 Dexterity saving throw, taking 2d6 lightning damage on a failed save, or half as much damage on a successful one.

Melee Weapon Attack: +2 to hit, reach 5 ft., one target. Hit: 3 (1d6) bludgeoning damage.
