A Bonus Web Enhancement for Draconomicon: The Book of Dragons

Draconomicon is the ultimate D&D game accessory about the legendary creatures that give the game its name. Packed into the pages of this book are new dragon prestige classes, spells, feats, dragonlike monsters, and full statistics for 120 sample dragons-all ten of the chromatic and metallic dragons at all 12 age categories. A few pages of new material on half-dragons round out the book’s offerings, but there just wasn’t room to include samples of those.

This article presents ten sample half-dragons, one spawned from each of the ten true dragons presented in the Monster Manual. Each description includes a brief personality profile and some background notes, plus a full statistics block for the creature and sample treasure appropriate for the encounter.
