TL;DR
7/10. The companion to the flaw guide, covering the half most writers skip: 100-plus virtues with their roots, behaviors, and the friction even strengths throw off. Its real lesson is that a virtue is a story engine, not a compliment. Useful and well made, but the less essential of the pair.
Everyone remembers to give a character flaws. Far fewer think as hard about virtues, and that imbalance is exactly the gap The Positive Trait Thesaurus fills. It is the companion to the flaw volume, and it does the half of the job most writers skip without realizing they are skipping it.
It explores over a hundred positive attributes, the obvious ones like courage, loyalty, and discipline, and the subtler, more useful ones like being perceptive, adaptable, patient, or disciplined under pressure. For each it covers the definition, where the trait tends to come from, the behaviors it produces, and how it shapes relationships and conflict.
The insight that makes it worth owning
The repeated, genuinely useful idea is that a strength is not automatically good for a character’s life. Loyalty can trap a character in a relationship or a cause long after they should have walked away. Honesty can wound the people around them and cost them allies. Discipline can curdle into rigidity. Even a virtue generates friction, and that friction is what makes it worth a writer’s attention rather than a gold star pinned to the character’s chest.
Take the entry on loyalty. It does not just praise the trait. It shows how loyalty can put a character in conflict with their own interests, how it can be exploited by someone who does not deserve it, how it can force an impossible choice between two people the character is loyal to. That is a story engine, not a compliment, and seeing virtues that way changes how you build a cast.
The book is also useful for the secondary cast, where it does some of its best work. A protagonist usually gets enough authorial attention to develop a real personality on their own, but the supporting characters are where writers cut corners, handing them a single trait and calling it done. Pulling a defining virtue from this volume, and then showing how it complicates the character’s life, turns a flat sidekick into someone who feels like they have an existence off the page. The mentor whose patience is also an inability to push the hero hard enough, the friend whose generosity leaves them perpetually broke, these are the small touches that make a world feel populated rather than staffed.

How it pairs with the flaw volume
I reach for it when a character is all damage and no spine. A protagonist built only from flaws is exhausting and hard to root for, a misery with legs. Finding the genuine strength underneath, and the way that strength sometimes works against them, gives the character a center to stand on and a reason a reader keeps following. The best characters usually have a virtue and a flaw that are two faces of the same trait: the loyal friend who cannot abandon a sinking cause, the honest colleague who cannot keep a necessary secret. This book and its companion together help you build that kind of two-edged character on purpose.
Verdict
It is slightly less essential than the Negative Trait volume, only because writers tend to need flaw help more often than virtue help in practice. But as a pair the two give the complete picture, and this is the half most likely to be missing from your work. A well-made, focused reference that quietly fixes the all-damage protagonist.

Frequently Asked Questions
What is The Positive Trait Thesaurus?
A reference cataloging more than 100 positive character attributes, each with its causes, behaviors, and effects on relationships and conflict. It is the companion to The Negative Trait Thesaurus.
Why would strengths need a whole book?
Because virtues are as revealing as flaws and create their own friction. Loyalty, honesty, and discipline can all work against a character, and the book shows how each strength becomes a story engine rather than a compliment.
Should I get this or the Negative Trait Thesaurus first?
If you can only get one, most writers need the flaw guide more. But the two are designed as a pair, and the strongest characters often have a virtue and a flaw that are two faces of the same trait.
Who is it for?
Writers whose characters are all damage and no strength, or anyone building a cast that needs distinct, balanced personalities with strengths that complicate rather than simply flatter them.
