Lone Colossus Games will release Tome of Intangible Treasures, a new 5E compatible rulebook, into retail on August 20, 2025.

This new compendium offers players rules on rewarding characters for in-game accomplishments as well as mechanical character growth options. The book sports over 450 ways of rewarding characters for heroism and other such feats, such as boons, blessings, advanced trainings, and more. It also has information that helps smooth out multiclass characters so that they work better with the mechanics, and histories for character flavor.

It will retail for $49.99.

Cubicle 7 also recently revealed a 5E compatible book for retail (see "Cubicle 7 Delves into 'Vault 5E'").
