4 More 5e Magic Items

I love making these!

Blurring Cloak
Wondrous Item, very rare (requires attunement)
While wearing this cloak, you can speak its command word as an action to gain the effect of the blur spell, which lasts for 10 minutes or until you remove the armor or use an action to speak the command word again. This property of the cloak can’t be used again until the next dawn.

Horn of Arctic Air
Wondrous Item, rare
The horn has 3 charges and gains 1d3 expended charges daily at dawn.
You can use an action to speak the horn’s command word and then blow the horn, which emits a blast of freezing air in a 60-foot cone. Each creature in the cone must make a Constitution saving throw. A creature takes 8d8 cold damage on a failed save, or half as much damage on a successful one.
A creature killed by this effect becomes a frozen statue until it thaws.

Potion of Contagion
Potion, very rare
When you drink this potion, you suffer the effects of the contagion spell (save DC 16). The potion’s light green color masks its nature.

Ring of the Reaper
Ring, rare
The wearer has a measure of protection from death. If the wearer would drop to 0 hit points as a result of taking damage, the target instead drops to 1 hit point, and the ring loses a charge.
If the wearer is subjected to an effect that would kill it instantaneously without dealing damage, that effect is instead negated against the target, and the ring loses a charge.
The ring has one charge per day, renewed at dawn.
