create a minecraft item that has the following description: 'Create a Minecraft mod where the player begins as a normal human. Upon using a one-time-use item, they unlock the /deal command, allowing them to form a pact with a female version of Nightmare Sans. This pact grants the ability to gain experience from defeating mobs and to begin leveling from level 1 to 20. When the deal is made, the player becomes half-monster and gains the passive ability to perfectly dodge all incoming attacks. Dodging consumes stamina from a visible stamina bar that regenerates over time and only appears while dodging. Dodging is active by default but can be toggled off with /dodge. The player's max HP is set to 10 using attribute modifiers, not potion effects. Each level-up increases attack, defense, and health via scaling attribute buffs. Nightmare regularly communicates with the player in a calm, intelligent, slightly manipulative, and increasingly affectionate tone. Her interest in the player deepens as their power grows.
At level 20, the player unlocks the /reset command, which resets their level to 1 and grants a permanent EXP boost. After their first reset, the player becomes Half-Monster (Something New) and gains access to the Determination mechanic. A Determination bar appears in the /status screen, and it rises with every mob killed. At 100% Determination, the player reaches Soul Stage 2, Killer, becoming stronger and faster. At 200%, they reach Soul Stage 3, Crazy, gaining more power with increasingly erratic behavior. At 300%, they enter Soul Stage 4, Uncontrollable, becoming berserk and ignoring player commands as they attack all nearby targets. These soul stage transitions reflect the player's growing instability, and Nightmare's dialogue becomes increasingly intense and obsessive as the stages evolve.
After completing 10 resets, the player unlocks /truereset, which returns them to level 1, resets their reset count, and increases the level cap to 40. Once the player completes 5 true resets, they become Killer!Killer (God Slayer), the strongest variant of the Killer!Killer archetype. Upon transformation, the /status command is replaced with /killerstatus, displaying current level, Determination, max HP, attack, defense, buffs, and tier. From this point onward, /reset and /truereset are replaced with /erase, which destroys the current timeline, resets the player to level 1, and increases their tier level.
There are six total tiers. Each time the player reaches their current maximum level and uses /erase, their tier advances. Tier 1 begins at level 40. Tier 2 increases the level cap to 80. Tier 3 raises it to 120. Tier 4 pushes it to 160. Tier 5 extends it to 180. Tier 6 unlocks the final level cap of 200. Upon reaching Tier 6 and maxing out at level 200, the player gains access to /TotsukaSlash, a powerful attack exclusive to Killer!Killer that cleaves through all enemies and is capable of killing even gods in a single strike. Only Killer!Killer can use this ability. With each tier gained, Nightmare’s obsession and reverence toward the player deepen to unnatural levels, constantly reflecting her awe and worship for what the player is becoming.
All progression systems, soul stage behavior, tier scaling, stats, and commands must function correctly. Include working versions of all required commands: /deal, /dodge, /reset, /truereset, /erase, /status, /killerstatus, and /TotsukaSlash. Fully functional cheat/debug commands must be included for manually adjusting player level, Determination, tier, form, and EXP.'
