Okay, I've been creating, scripting, and writing a relatively basic quest on and off for the last two weeks or so. In the end, I chopped it down to the following, which is more or less how it will come out in the end:
Author's Note: Keep in mind that this quest was scripted using the most basic variables and flags as possible. In other words, I'm not stupid, I'm lazy.
The quest begins inside my "house." Nothing spectacular, just your average, solidly-designed, Classic playerhouse. Inside, order five shots from the mini-bar (a cook gives you the hint to do so) and you become "drunk." After a blacking-out sequence, you are warped, and wake up in a bed inside the servants quarters(though every time, the player lands on the bed instead of in it. Hmph.) The nurse tells you to get some Addvil ("What? No, that's not a typo. That's copyright evasion at its finest.") from Xythar's medicine closet, and sets the flag "xythardunnyopen" which allows access to the previously occupied bathroom.
Inside, you'll find the Addvil, which cures your hangover (fail to get the Addvil, and you steadily lose hearts, a la the lava caves) and a lever. Pull the lever and be warped to the dungeons, where Xythar announces his plans for Graal domination using his line of "s00p3r n00by" robots ("th3y r 1337!"). Defeat Xythar, a relatively simple mini-boss reminiscent of Ryven --- but with downs syndrome, and inferior scripting. Search his body for the key to the underground factory.
Go upstairs, and use the key on a previously locked door. Shut down the assembly line of s00p3r n00bys by hitting the switch, and witness my amazing usage of putexplosion. Then face s00p3r n00by, the final boss.
Actually, that's the only thing I'm having trouble with. I want him to be somewhat difficult, but also want him to resemble a n00b. It's impossible to do both.

Listen to his dying words ("No! Don't PK me! Please, I'll give you 14 gelat if you please don't kill me!") The prize is undecided; but I've been messing around with the code for a "Cherry Bomb", a small bomb that explodes the second it hits the ground.
That's it, really. And thoughts, suggestions, rotten tomatoes to throw at my head? All are appreciated --- especially advice on how to handle the final boss. Right now, I'm thinking of having him just be very annoying, as in he runs out of the water, hits you, then jumps back in so he can't be hurt.

Stuff like that. I'm hoping to finish it and submit it to Classic by school, or a little bit afterwards.
