Veldrin's Smoke Clone

Smoke emits from your outstretched palm and creates a grey smoky duplicate of yourself. For the duration, your smoke clone stays no farther than 5 feet from you and imitates your every action. The smoke clone has the same spell and attack modifiers as you and cannot be targeted by any spells. Your smoke clone cannot cast spells higher than 1st level (if you cast a 1st-level spell at a higher level, the clone instead casts the spell at the 1st-level) and can only take 1 attack action. Your clone takes these actions on your turn, after you've taken your actions. If your clone cannot carry out an action that you are doing, it instead gives you 1 of these 3 benefits.
Help. The smoke clone gives you advantage on a skill check you make.
Block. Your smoke clone gives you +2 to your armor class.
Attack. Your smoke clone makes an attack action.
