Practitioners of magic well know the power of names, but wizards who follow the tradition of Onomancy use their magic to manipulate the words that encompass existence. Onomancers expand their study into language itself, searching for threads of magical significance that weave through names. Something that is named stands out in the multiverse, distinct from the tapestry of creation all around it.
That distinction creates power that onomancers seek to tap. By speaking a target’s true name, the wizard’s spells slip between the cracks of the target’s defenses, conforming to its essential nature through the power of its name. To protect themselves, wizards who follow this tradition often hide their true names, typically by adopting monikers and pseudonyms.

At 2nd level, you learn one language of your choice and gain proficiency with calligrapher’s tools.
At 2nd level, you can magically compel a creature to divulge its true name. As a bonus action, you target one creature you can see within 60 feet of you. The target must make a Wisdom saving throw against your spell save DC. On a successful save, you discern that this magic failed, and you can’t use this feature on the target again. On a failed save, the target is charmed by you until the end of your next turn, and you mentally learn the charmed target’s name or the fact that the target lacks a name.
You can use this feature a number of times equal to your Intelligence modifier (minimum of once), and you regain all expended uses of it when you finish a long rest.
Starting at 2nd level, you can bend magic to assist or hinder creatures through the power of their true names, and even use those names as an anchor to affect others around them. The Bane and Bless spells are wizard spells for you, and you add them to your spellbook. You always have them prepared, yet they don’t count against the number of spells you can prepare.
You can cast either spell without expending a spell slot if you speak the true name of one target of the spell as part of casting it. You can cast the spells in this way a number of times equal to your Intelligence modifier (a minimum of once), and you regain all expended uses when you finish a long rest.
At 6th level, you learn words of power called Resonants, which allow you to tailor your spells through the use of a target’s true name.
Resonants Known. When you gain this feature, you learn two Resonants of your choice, which are detailed in the “Resonant Options” section. Each time you gain a level in this class, you can replace one resonant you know with a different one.
Using a Resonant. You can use one Resonant when you cast a wizard spell with a spell slot and speak the true name of one creature targeted by the spell. Speaking the name is part of casting the spell.
You can use Resonants a number of times equal to half of your wizard level (round down), and you regain all expended uses when you finish a long rest.
Resonant Options. Here are your options when choosing a Resonant:
At 10th level, you learn two new Resonants of your choice from your Resonant Utterance feature.
At 14th level, you have learned how to bypass a named creature’s defenses against certain types of damage. When you cast a spell that deals damage to a creature whose true name you speak as part of casting the spell, you can cause the spell to deal force or psychic damage to the creature, instead of the spell’s normal damage type.
