Creature Statblock

Turns any creature from any world, book, film, game, myth, or song into an original, playable 5e-style stat block.

Overview

Turns any creature from any world, book, film, game, myth, or song into an original, playable 5e-style stat block. Returns AC, HP, ability scores, challenge rating, traits, and actions as original game statistics (not a copied published block). Optionally target a challenge rating. Bridges the bestiary and rollforge clusters. Use it as a creature stat block generator API or a source of homebrew monster stats for any being.
