Twin Destinies

Using this powerful incantation, you can split off a portion of your consciousness into a duplicate Vessel, which can move an act independently of you. The Vessel is inextricably linked to you and a copy of you in every way, except as otherwise stated here. It can move and take bonus actions, actions, and reactions as you can. All non-magical items on your person are also "copied" to the Vessel, but magical items are not copied.

The Vessel 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. It shares your personality, alignment, and demeanor. The Vessel is also subject to the following limitations:

1. The Vessel cannot concentrate on spells or other effects which require concentration.
2. When either you or the Vessel casts a spell, the other expends the appropriate spell slot.
3. When either you or the Vessel uses an ability which can be used a limited number of times per short rest or long rest (including abilities such as Ki, Sorcery Points, or Lay on Hands), the other is also deemed to expend the same amount of that resource.
4. When either you or the Vessel takes any damage or healing, the other takes damage or healing in the same amount, which may not be reduced or modified in any way.
5. When either you or your Vessel are subject to the Blinded, Charmed, Deafened, Exhausted, Frightened, Invisible, Incapacitated, Paralyzed, Petrified, of Poisoned conditions, the other is also affected.
6. You are affected by any spell which affects your Vessel, and vice versa.
