Thunder's body double

The caster touches one humanoid creature of their choice, building and tethering an almost exact body double of and to said humanoid, sharing personality, skills and memories.

the rules of this body double are as follows:

• The body double has it's own free will, but must act as close to the target humanoid as possible.
• it has one hit point and temporary hit points equal to the casters spellcasting modifier and shares class/race features, ability scores and armour class with the target.
• it cannot have resistances from any race or class features.
• if the target dies, so does this.
• it cannot have subclass features.
• if the body double dies before the target, the body double becomes inert, the consumables used to make them becoming dead and unusable.
• it can only attack with unarmed strikes and cantrips (if it can cast any)
• The body double is controlled by the DM.

the clone can be distinguished as a clone with a successful intelligence(investigation) or wisdom(insight) check, with the DC equalling the caster's spell save DC.
