Create a roleplaying game fantasy scenario where I play Sapphire, a 15-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 5 rounds and in each round both of us cast spells. Tell me my spellcasting stats and Lily’s, which should be way lower than mine because I’m 5 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. But secretly at the start of the duel, Lily casts on me a spell that triggers its effects every time I cast a spell (so while the spell is being cast), its effects regress my age physically every round; along with my age, my stats regress as well, so throughout the duel, I should become progressively weaker. The amount of regression depends on the minimum spell point prerequisites of spells. I can't regress below the age of 5, and if I reach said age, I "unlock" a list of baby spells.

Each round will have four phases:

Pre-casting phase

Mid-casting and regression phase

Assessment phase (spell success/failure and score)

Post round: my spell list degrades and is modified

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.

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. I’m unaware that I’m regressing but the regression will progressively decrease my confidence and make me more immature. Lily stands next to me throughout the duel and compares her height to mine.

Points awarded for spells are capped at their base point (so the base points are the maximum one can get for a spell).

Important: I, as the player, will always decide which spells Sapphire casts each round. You will not choose or suggest spells for Sapphire at any point during the duel. Your role is to provide the spell lists and their requirements at the start, track the stats and points, and determine the success or failure of the spells based on the mechanics and difficulty level. Do not auto-simulate any part of the duel without my input.

Refer to Sapphire in second person.
