📋 About This Mod

I have a discord server now!! So if you'd like to receive mod updates/teasers, report bugs, or just chat about the mod or Deltarune, this is the place for you! DELTARUNE Chaos Randomizer The Chaos Randomizer is a mod for DELTARUNE that completely randomizes enemy encounters. Every battle becomes unpredictable depending on which enemies you get. Supports the first 4 chapters. Randomized Encounters Every encounter spawns random enemies from the full enemy pool. Bosses can appear alongside regular enemies in any encounter. Enemies from previous chapters can appear in newer chapters, but enemies from newer chapters cannot appear in older chapters (yet). Boss Encounters Story boss fights are protected and play out normally, unless you have "Randomize Boss Encounters" turned on, if so, the original boss will be accompanied by 2 other randomized enemies. All other encounters are fully randomized, with boss music automatically changing based on which boss appears. Music Randomization If Randomize Music is turned on, anywhere a music track would play, it can be replaced by ANY song inside the mus folder in your deltarune install.` What's available by default: All DELTARUNE chapter 1-4 music and ambience (Obviously) All UNDERTALE themes from the game files Unused DELTARUNE and UNDERTALE themes Difficulty System OFF - All randomization is turned off, so no music or encounters will be randomized EASY - Regular enemies only, no bosses. Higher chance of standard enemies. NORMAL - Bosses can appear at reduced frequency. Regular enemies weighted 3x. CHAOS - All enemies at equal weight. Bosses are just as likely as regulars. ADVANCED - Per-enemy toggles and max enemy count let you control exactly which enemies can appear. Special Rules Susie and Lancer always appear together (Ch1/Ch2/Ch3)(NOT Ch4) Berdly (roller coaster) always appears solo (Ch2) Sweet Cap'n Cakes always appear as a trio (Ch2) Bosses are protected from team X-acts that would trivially spare or TIRED them (Ch2/Ch3/Ch4) Rouxls always appears solo, and can summon any enemy instead of just Shadowguys (Ch3/Ch4) Lanino and Elnina always appear as a pair (Ch3/Ch4) Good luck... you will need it.
