What is Kobold Plus Fight Club?

Updated

Kobold Plus Fight Club (koboldplus.club) is a web tool for tabletop role-playing games, primarily Dungeons & Dragons 5th Edition. It is a community-built successor to the well-known encounter-building tool "Kobold Fight Club," and its tagline — "The first rule of Kobold Fight Club is 'Yip Yip!'" — is a direct nod to that heritage. If you are a Dungeon Master looking for a fast way to build and balance combat encounters, this is the kind of site you would visit. Note that the available page data for this site is very limited, so the specific feature set should be confirmed by visiting the site directly.

What "Kobold Fight Club" refers to

Kobold Fight Club is a long-standing fan-made encounter builder for D&D 5e. It lets a DM select a party size and level, then add monsters to see whether the resulting fight is trivial, easy, medium, hard, or deadly according to the official encounter-building guidelines. The original tool became a staple of DM prep because it automated the math that the Dungeon Master's Guide describes in prose.

Kobold Plus Fight Club carries that name forward. The "Plus" suggests an updated or extended take on the original, which is common when a popular fan tool goes unmaintained and the community rebuilds it.

What a tool like this typically does

Based on the genre of the original, an encounter builder of this type generally lets you:

  • Set the party — number of player characters and their levels.
  • Add monsters — search a monster list, often filterable by challenge rating, type, or sourcebook.
  • See the difficulty — an automatic rating (trivial / easy / medium / hard / deadly) that updates as you add or remove creatures.
  • Adjust the count — increase or decrease how many of a given monster appear in the fight.
  • Save or share — some versions let you export an encounter or keep a list for later.

The exact set of features on koboldplus.club is not documented in the available page evidence, so treat the list above as the expected baseline rather than a confirmed feature list.

How to check whether it fits your needs

  1. Open koboldplus.club in a browser.
  2. Look for party inputs (size and level) and a monster search field — these are the core of any encounter builder.
  3. Add a monster and confirm the difficulty rating changes as you adjust the party or the monster count.
  4. Check whether the monster list matches the sourcebooks your table uses, and whether you can filter by them.
  5. If you need saved encounters or exports, verify those options exist before relying on the tool for campaign prep.

If the site loads and responds to those inputs, it is functioning as an encounter builder. If it does not, it may be down, moved, or repurposed.

Things to keep in mind

  • It is a fan tool, not an official product. Encounter difficulty ratings are a planning aid, not a guarantee — actual fights depend on tactics, terrain, and party composition.
  • Rules versions matter. D&D 5e and its 2024 revision handle some encounter math differently. Confirm which ruleset the tool's numbers assume.
  • Availability can change. Community tools sometimes go offline or move domains. If koboldplus.club does not load, search for the current home of the project.
  • Verify before you prep. Because public information about this specific site is thin, test it with a throwaway encounter before building a session around it.
