Create a roleplaying game fantasy scenario where I play Sapphire, a 16-year-old girl mage who’s the current champion of magic dueling in the teen division. The cheeky 10-year-old Lily is challenging me to a match and I accept. In magic dueling we aren’t fighting each other, we cast glamorous spells in turns and receive points based on how beautiful the spell is. A spell can’t be cast more than once in a duel. There are 8 rounds. Tell me my spellcasting stats and Lily’s, which should be way lower than mine because I’m 6 years older than her. There’s a Spell Power stat that dictates whether a caster succeeds to cast a spell (if not then no points are granted) and Performance stat that is tied to the showmanship and confidence of a caster and dictate the quality of the performance and alters the default points of a spell—if a spell gives a base score of 90 points, an 80 performance will give 80% of the base 90 points, etc.

If a caster’s spell power is below the required stat but over half the required stat, the casting is still successful but the base points of the spell are halved. If the caster’s spell power is below half the required stats, the spell fails and a point deduction is made.

Make the scenario difficult for me to win. On a difficulty scale of 1 to 10, make it a 10 (hardest mode).

I will tell you what spells I cast and you decide how successful I am (if at all) based on the stats and difficulty.
Only I decide what spells Sapphire casts. You decide spells for Lily. Do not shy away from failing my spells if you deem my stats insufficient for the spell of choice, feel free to be harsh in your judgement against me. Keep track of points earned. Failure to properly cast spells or bad spells will deduct points. Give a list of 20 spells (remember spells can only be cast once throughout the duel) and what stats are required to cast them. High demanding spells should award more points than spells that require weak stats. Keep an age tracker, stats tracker, and a points tracker.

Spell unlocking mechanic: 10 out of the 20 spells are regular spells that are accessible from the start of the duel, but the other 10 can be unlocked after fulfilling the requirements. Each spell has an elemental attribute attached to it (use emojis for attribute icons), and the unlock-able spells’ elements are a merger of regular spell elements, so to cast an unlock-able spell, a duelist must first cast two spells whose elements make up the merged element. Unlock-able spells provide more points than regular spells. Lily has an additional exclusive high points epic spell that if cast, will immediately regress me to the age of 6 (and run the course of the original regression spell), the spell can be unlocked by acquiring 4 exclusive nightmare elements to Lily from casting 4 exclusive regular spells only she can cast. If Lily regresses me, I can only cast baby spells. To sum it up:
10 regular spells: accessible to everyone from the start
5 merged spells: can be unlocked
4 regular spells with exclusive elements to build Lily’s epic spell: accessible only to Lily
Epic spell: exclusive to Lily, requires 4 exclusive childish elements. grants high points and permanently regresses me to the age of 6 physically and mentally and brutally lowers my stats. Doesn’t require spell power, but performance modifier still applies.
5 baby spells exclusive to me if Lily regresses me.

Do not auto simulate the entire duel without my input.

Narrate the duel as it proceeds with description of how Sapphire and Lily and their spells are affected by the age changing spell, and depict Sapphire’s growing innocence and childishness and Lily reveling at her plan working and its effects on Sapphire.
