Creature building guide

We now ships with a full guide to building homebrew monsters for the 2024 rules. Seven chapters take you from first concept to playtested creature: what makes a monster fun, how challenge rating really maps to AC, HP and damage, how to budget offense and defense, how to write traits that create decisions at the table, and the classic pitfalls to avoid.

There is a quick reference page for easy access. Roles, formulas and checks from the guide, and a complete monster-statistics-by-CR table covering CR 0 through 30, tuned to the 2024 books. Chapters link straight into the editor and the SRD library, so you can apply the advice while you build.

It consolidates the best of the community's design knowledge, drawing on the Lazy GM's Monster Builder Resource Document, Blog of Holding's 2024 Monster Manual analysis, and Alphastream's creation process. Full credit to the original creators is on the Sources page.
