Kobold+ Fight Club

Kobold+ Fight Club turns a party description into an encounter budget and a searchable monster list. A game master chooses character levels, difficulty and source books, then adds creatures manually or asks the generator for a combination that fits. Filters reduce a large bestiary by challenge rating, type, environment or source. Custom monsters can be imported from JSON, CSV files or a Google Sheet. The site now includes separate strategies for the 2014 and 2024 D&D encounter rules as well as supported third-party approaches.

The displayed difficulty is arithmetic, not a prediction of the table's experience. Action economy, terrain, surprise, control magic, player skill and depleted resources can move a fight far from its label. Source listings may also include material a user does not own, so the builder is not the rules text for every monster. Imported data deserves inspection before play. Kobold+ is most useful as a fast constraint checker and search interface; a game master must still assess whether the encounter is interesting, comprehensible and survivable for this particular group.
