Conjure Creature – Import Custom D&D Monsters into Roll20

Skip the tedious Roll20 form-filling and get back to running your game.

If you’ve ever built a custom monster and spent 20 minutes typing every stat, trait, and attack into Roll20’s NPC sheet, you know the pain. This extension bridges your monster creation workflow between cros.land and Roll20.

WHAT THE EXTENSION DOES

🐉 Create monsters on cros.land: Use the AI-powered statblock generator to build D&D 5e monsters (5 free per day).
🔄 Auto-sync to the extension: Saved monsters automatically appear in the extension popup.
📤 Export to Roll20: Open a Roll20 NPC sheet, pick a monster, and click Export to Roll20.
⚡ Auto-fills everything: Name, stats, AC, HP, saves, skills, traits, actions, legendary actions, spellcasting metadata, and more.
🧙 Supports complex creatures: Spellcasters, multi-attack monsters, and monsters with many abilities all work.

ABOUT ROLL20

This extension is designed for homebrew monsters you create yourself. It fills standard NPC form fields, the same ones users type manually. It does not access or modify marketplace content. Not affiliated with or endorsed by Roll20.

WHY I BUILT THIS

I’m a longtime Game Master and the creator of the AI tools at cros.land. Entering custom monsters into Roll20 was one of the most frustrating parts of prep, so I built something to make that process instant.

Create once. Import instantly. Run your game.
