Twinned Flesh

Your touch physically transforms another Humanoid of similar size to make it look and sound exactly like you. The target's Strength score changes to match yours, but its other statistics and personality stay the same. The target's clothing and other equipment don’t change in appearance, size, or shape to match its new form, and the spell doesn't grant the target the ability to speak languages it normally doesn't speak. 

The spell has no effect on a target that isn't a Humanoid or that doesn't have the same size category. A Dispel Magic spell can end the magical effect as normal. The spell also ends if the target speaks its true name seven times while facing a mirror.

Using a Higher-Level Spell Slot. You can transform a Humanoid into the likeness of another Humanoid of similar size that isn't you, provided you touch both creatures during the casting of the spell.
