Oath of Hexes

Those who swear an oath of hexes are sworn to witch covens, fey
creatures, and occult deities of magic, fate, and death. In exchange,
this sacred oath empowers paladins with fickle magic to curse those
who would try to tempt fate or escape the ire of the Old Gods.
Tenets of Hexes
Serve the Occult. Deities with power over the future have
infused you with occult magic. Through your oath, you are
made a mortal vessel for their inscrutable will.
Keeper of Secrets. This world harbors dark secrets which are
best kept long forgotten. You stand as the protectors of those
secrets, preventing them from falling into the hands of weakwilled
mortals who would misuse them to evil ends.
Arbiter of Fate. The strands of fate were woven long ago, and
it is folly to fight them. Misfortune befalls all.
Show No Mercy. Though some think your strange powers are
dark or corrupted, you vanquish evil with the very curses and
magics that they would use against you. Show no mercy to
those who resist their fate.

Channel Divinity
3rd-level Oath of Hexes feature
You gain the following Channel Divinity options:
h Curse of Hexes. As an action, you curse one creature you
can see within 30 feet of you. When you curse a target, choose
an ability score. The chosen creature has disadvantage on
attack rolls, saving throws, and ability checks using that ability
score for one minute or until it drops to 0 hit points or falls
unconscious. At the end of each of the cursed creature’s turns, it
can make a Charisma saving throw against your spell save DC.
On a successful save, the curse ends.
h Curse of Torment. As a bonus action, you curse one creature
you can see within 30 feet of you. Searing pain wracks the target
for one minute. While suffering this pain, it takes necrotic
damage equal to your paladin level at the start of each of its
turns. Each time it takes this damage, it can make a Wisdom
saving throw against your spell save DC. On a successful save,
the pain ends.
Bewitching Aura
7th-level Oath of Hexes feature
You emit an eldritch aura out to a range of 10 feet. When an
enemy hits you or a creature within 10 feet of you with an attack,
you can use your reaction to force that enemy to make a Charisma
saving throw against your spell save DC. On a failed save, you can
magically redirect the attack to another creature of your choice
within 10 feet of you and within range of the attack. The new
target is hit by the attack and suffers all damage and effects.
At 18th level, the range of this aura increases to 30 feet.
