This spell becomes a cantrip to a paladin only if the paladin gets a holy symbol blessed by a cleric. Cleric must in turn bless both paladin and holy symbol. Holy symbol/artifact must remain on paladin at all times.

A white orb of crackling energy streaks toward a creature within range. Make a ranged spell attack against the target. On a hit, the target takes 1d8 radiant damage. Undead, zombie, fiends and enemies of an evil nature or makeup,  take 1d12 radiant damage.

The spell creates more than one orb when you reach higher levels: two orbs at 5th level, three orbs at 11th level, and four orbs at 17th level.

You can direct the orbs at the same target or at different ones. Make a separate attack roll for each beam.
