Rajhin's Mantle (5e Equipment)
From D&D Wiki
Wondrous Item, legendary (requires attunement)
You can use a bonus action to create an illusory duplicate of yourself. The duplicate is a creature, partially real and formed from shadow, and it can take actions and otherwise be affected as a normal creature. It appears to be the same as the original, but it has half of your hit point maximum and is formed without any Equipment. Otherwise, the Illusion uses all the same Statistics as you.
The duplicate is friendly to you and creatures you designate. It obeys your spoken commands, moving and acting in accordance with your wishes and acting on Your Turn in Combat. The duplicate lacks the ability to learn or become more powerful, so it never increases its level or other Abilities, nor can it regain expended Spell Slots.
If the duplicate is damaged, when you use a hit dice to heal yourself, the duplicate regains an amount of hit points equal to half of the rolled value. The duplicate lasts until it drops to 0 hit points, at which point it reverts to shadow and disappears instantly.
You may only have 1 illusion active at any point in time. If another illusory duplicate is created, the previous one vanishes.
The mantle regains use of this effect at dawn.
If this item is removed from your person, any currently active duplicates that were created by this item are instantly destroyed.
