I like characters that protect others. Let’s make a cantrip for clerics who do less damage but help a bit more.
Shield the Faithful
Casting Time: 1 action
Range: 50 feet
Choose a creature in range. That creature get +1 to armor class until the start of your next round, and then choose a creature engaged with the primary target to make a Constitution saving throw. On a failure, that creature is bathed in scorching light and takes 1d6 radiant damage.
The spell’s damage increases by 1d6 when you reach 5th level (2d6), 11th level (3d6), and 17th level (4d6).
