create a minecraft item that has the following description: 'Create an Undertale AU system where players start by randomly receiving one of three races: Human, Half-Monster (human-skeleton hybrid), or Monster (skeleton). Players begin as base characters—Frisk or Chara for Humans, Sans or Papyrus for Half-Monsters and Monsters—and unlock their AU identity only after their first reset. Supported AUs include canon and fan-recognized types such as Underswap, Underfell, Outertale, DreamSwap, SwapDream, Fellswap, Swapfell, Swapfell Emerald, MafiaTale, Xtale (Cross), Horror, Ink, Error, Nightmare, Geno, Insanity, Chicken’s Insanity, Infected, Error404, Omnipotent, Alpha, and Alphatale versions of Frisk and Chara. Players select a route with commands: /pacifist, /neutral, /genocide, /insanity, /error, or /determination (Sans-only), with /route showing their path. Pacifists gain spare points (max 1000) via /spare; Genocide and Insanity gain EXP (max levels 20 and 40); Neutral gains both EXP and spare points (levels 10 and 500); Error advances through glitch milestones; Determination evolves Sans into Geno Sans (Pacifist) or Dust Sans (Genocide), progressing through Dusttale stages like Snowdin, Waterfall, Hotland, and Corridor. Players can only /reset after maxing progression on their route to ensure mastery before evolving.
After 20 resets, /true_reset unlocks, wiping prior resets and evolutions but granting permanent buffs and faster progression. Specific true reset counts unlock Transcendent AU forms and a power scaling hierarchy with unique custom AUs per tier and character, ensuring diversity and no repeats.

Specific characters evolve preset paths: William → Error404 Sans, Adam → Alphatale Sans, Jacob → Infected Sans, Ares → Omnipotent Sans. Cosmic Essence, Nexus Code, and Conduit Souls (soul replacements embodying fundamental reality laws) unlock at specific true reset counts regardless of AU, are one-time-use, soulbound, and persist through death and resets. Occasionally, Cosmic Essence and Nexus Code combine for powerful effects.
The system begins with a one-time-use Fated Soul item that determines player race and permanently binds upon use; the same applies to Conduit Souls, Cosmic Essence, and Nexus Code. Monsters and Half-Monsters have stamina for toggleable automatic dodging (/dodge) and mana. Sanity drops on Genocide, Insanity, and partly Neutral routes, causing voices and killing urges managed by AI with custom effects. Insanity progression involves chaos tasks and instability milestones. Players get notifications for EXP, spare points, sanity, resets, and evolutions. Error and Insanity characters are glitchy, unstable, and near-unkillable at high tiers.
Players receive notifications for EXP, spare point gains, sanity effects, resets, true resets, and AU unlocks. The /status command shows full details: race, AU, route, EXP, spare points, soul type, resets, true resets, sanity, stamina, mana, active buffs, conduit status, Nexus Code, and Cosmic Essence. Switching from Genocide to Pacifist forces Neutral with unique dialogue. Error and Insanity evolutions reflect instability, with high-tier forms near-unkillable or chaotic. The AI ensures all commands, evolutions, items, reset logic, route conditions, sanity penalties, buffs, dodge mechanics, scaling, and progression work as a balanced, permanent system. Progression is locked to route-specific caps; all unlocks function exactly as specified.
Every AU has multiple evolutions per route with scaling buffs, soul traits, and conduit effects. The /status command provides a full summary. Players trying to switch from Genocide, Insanity and or Error to Pacifist get unique dialogue and fail. Make sure that everything gives the correct buffs and that whenever the player kills a mob they gain the correct exp for genocide and or insanity and also for error and determinations unique route they get whatever point you decide for them. Pacifist must look at a mob to spare and that will instantly despawn that mob. Notify the player whenever they level up. Each kill should tell the player how much exp they got and once they get enough exp they will level up. When the player types /spare at a mob it rewards spare points and despawns the mob.'
