Not Enchanter, like the wizard, the Enchanted. That basic idea is this, the class grants that character to absord and make certain spells cast on them permanent. They are like humaniod magic items. So at each level they can accept a choice of an enchantment. Like at level 5 instead of just getting an extra attack like a fighter or Paladin does, they are under a permanent and undispellable Haste spell. And these aren't spellcasters, they are instead simply the perfect living enchantable material for Wizards, Sorcerers, Clerics, Artificers, Bards and Druids. Living magic items that learning master their bodies enough to accept more enchantments and more powerful enchantments. Maybe even a few other quirky abilities, like anyone touching the character can use them as a spell casting focus even if they normally don't use such focuses like Rangers. Some spells cast on them would change to fit being placed on a character instead of say a sword. And subclasses would be based around gaining the same magics as a particularly interesting magic item.
