Simulacrum

Using a bonus action, you can manifest a spectral copy of yourself that appears superimposed over your body, you decide if it should focus on a nonmagical object that is a suit of armor that you wear or a simple or martial weapon that you carry. Until the end of your next turn or until you let go of the object, the object grants a +1 bonus to AC if it's armor or a +1 bonus to attack and damage rolls if it's a weapon.

You can use this ability once per short rest.
