Enchanter
An Enchanter is a form of Specialist Wizard in Dungeons & Dragons. Specialized in the school of Enchantment, this is one of those cases where D&D fans are practically talking a different language to other fantasy fans; in most fantasy, "enchanting" is used as the term for transforming mundane items into powerful magical items - but, in D&D, this is the providence of the Artificer. The Enchantment school is instead focused on mind-fuckery; these wizards excel at seizing control of the will of other beings and reducing them to puppets.
Ironically, despite the fact that this is obviously a pretty evil thing to do when you think about it (not to mention a really /d/oor-opening power-set), enchanters traditionally aren't looked upon as evil in D&D - although there was an article in Dragon Magazine pointing out that, if anything, enchanters should be regarded with just as much fear and distrust as Necromancers. There's a reason the Undead Master, a necromancer kit from Advanced Dungeons & Dragons focused on being an archetypical pulp-style evil wizard, is essentially a threeway Conjurer/Enchanter/Necromancer hybrid.
This might be because, after 3rd edition came out, Enchantment took a huge nose-dive in terms of potency; almost every single monster type in the game is immune to Enchantment school spells.
5th Edition's Arcane Tradition
Enchanters have their ability to hypnotise others enhanced through their specialization; Hypnotic Gaze (2nd level) lets them effectively make a free charm attack on a creature within 5 feet, Instinctive Charm (6th level) lets them try and bewitch an attacker and so redirect its attack as a reaction, Split Enchantment (10th level) lets them hit two creatures with a single 1-target Enchantment spell, and finally, Alter Memories (14th level) lets them not only make a charmed creature unaware of its being charmed, they can also try to blank out its memories of some of the time it spent under their control.
