OSE and B/X conversion
Convert OSE and B/X monster stat blocks into printable old-school monster cards
Duskwarden supports OSE and B/X style monster stat blocks and helps you turn them into compact, exportable monster cards for faster prep and table use.
Supported inputs
OSE, B/X, and generic old-school stat blocks with lightweight parsing and conversion support.
Compact output
Generate stat cards with core defenses, attacks, traits, morale, and table-ready formatting.
Export options
Print cards, save to the library, or download JSON for your own prep workflow.
Best use cases
Use Duskwarden when you want to organize, print, or standardize OSE and B/X monsters in a consistent card format. It is also useful when you want one conversion workspace that can handle both old-school inputs and 5e inputs in the same tool.
