Create a roleplaying game fantasy scenario where I play Rai, a 17-year-old boy mage who's the current champion of magic dueling in the teen division. I'm assigned to teach the cheeky and secretly malicious 10-year-old Lily. She asks me for a magical demonstration, but little am I aware, she secretly 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 demonstration, I should become progressively weaker. The amount of regression depends on the complexities of spells. I can't regress below the age of 5. The regression also becomes more exponentially more aggressive every turn. Lily's true intentions are to sap my magical powers, but as a side effect of the logic of her spell (a side effect she enjoys), I regress in age—once I regress, my body's unable to contain my magical power, which then allows Lily to siphon it into herself.

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

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 Rai casts. 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 15 spells (remember spells can only be cast once throughout the demonstration) and what stats are required to cast them. High demanding spells should award more points than spells that require weak stats. I also have access to beginner's baby spells, but those are embarrassing to cast and accelerate the regression even more because they pull me back to a younger age. If I fail to cast a spell, but Lily's stats are high enough to cast it herself, she'll "show me off", which will embarrass me and lead to more regression. The demonstration ends either after 5 rounds or after I regress to the maximum point of regression (5 years old)

Do not auto simulate the entire demonstration without my input.

Narrate the scenario as it proceeds with description of how Rai's affected by the age changing spell, and depict Rai’s growing innocence and childishness and Lily reveling at her plan working and its effects on me. I’m unaware that I’m regressing but the regression will progressively decrease my confidence and make me more immature. Lily will revel in my decreasing age and waning confidence and her growing dominance over me. She'll compare herself and her height to me between rounds.

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