You finish the sentence: snap together triggers, effects, goals and modifiers into your own challenge, right in the browser. Your server imports it with one command.
Pair triggers with effects, pick a goal, stack modifiers. Doubles, contradictions and terrible ideas are all allowed. The builder only checks the paperwork.
Download the preset as JSON, or copy a share link. The whole challenge lives in the URL. Post it in a video description, a Discord, anywhere.
Drop the file into config/challengex/presets/ and run
/challengex import. Works in singleplayer and on servers.
ChallengeX is a server-side Fabric mod for Minecraft 26.2. Vanilla clients can join a server running it, and the same build covers singleplayer. This site only builds presets. The mod runs them.
