Over the course of the casting you craft a suit of spectral armor around a willing creature, inlaying the suit with runic sigaldry meant to bind and protect. Until the spell ends the target's base AC becomes 13 plus your Intelligence modifier. The spell ends early if the target dons armor.
Choose one of the following types of creatures: Aberrations, Celestials, Dragons, Elementals, Fey, Fiends, or Undead. The armor affects the target in the following ways related to the chosen creature type;
Attack rolls made by the target against the chosen creature type are made with advantage,
Saving throws made by creatures of the chosen type against spells or effects originating from the target are made with disadvantage,
The target cannot be Charmed, Frightened, or Possessed by creatures of the chosen type,
Attack rolls made by the chosen type against the target are made with disadvantage,

The target is restrained,
The target makes a Charisma saving throw against the caster's spell save DC when attempting to cast a spell or similar effect, the attempt failing upon a failure,
