As a Magic action, you present your Holy Symbol and expend a use of your Channel Divinity to infect a creature you can see within 30 feet of yourself, which must succeed on a Constitution saving throw or have the Poisoned condition for 1 minute. While the creature has the Poisoned condition, it suffers the effects of one of the following magical contagions. At the end of each of the Poisoned creature's turns, the creature repeats the save, ending the condition on itself on a success.
Bloodmore
Whenever the creature takes Bludgeoning, Piercing, or Slashing damage, it takes an extra 1d6 Necrotic damage.
Joint Lock
The creature's Speed is reduced by 15 feet, to a minimum of 5 feet.
Ruby Eye
The target can see normally out to a range of 5 feet, but has the Blinded condition beyond this range.
