After running my daughter through the Choose-Your-Own-Adventure module, I thought she'd need some pointers on playing anything other than a fighter so I made up a little adventure where she played a rogue. The first thing I did was show her her hit points, armor class, and weapon damage on the Merisiel pregen sheet and ask her to compare them to what the numbers she was using as a fighter. She noted the numbers were all lower, and I told her that rogues don't want to walk right up to a goblin or a skeleton king and just trade blows; they want to be sneaky. She likes being sneaky anyway, so this was good. I showed her how a rogue could do more damage than the fighter by flanking or attacking from Stealth, and then I set Merisiel walking down a road near sunset and finding an inn that had been ransacked by orcs. She had to use Stealth to hide from the orcs until the main group went out to find more food and Perception to overhear their plans to eat the people locked in the barn in the morning. She failed her Stealth roll to sneak past the sentry left behind in the inn, and her first instinct was to go stab him; when I reminded her she was a rogue, not a fighter, and she could dash down the basement stairs instead, she got locked in the basement where she had to fight a dire rat. She picked the lock on the cellar door to get outside, sneaked past the guard at the barn door, climbed up the ladder on the silo to get into the barn, and got the prisoners out of the locked stall in the barn. One of them was Valeros, and she had to sneak back into the inn to get his armor and weapon. Then he created a ruckus in the barn to draw the guard in, she flanked with him, and they all rode away on the horses to Sandpoint to bring back soldiers to defeat the orcs.
Next I taught her to play a wizard. Ezren's mentor Gandalf (yeah, I know, I'm terrible at coming up with names, but she thought it was cool) had lost his favorite pen while picking mushrooms to make potions with in a cave outside Sandpoint and sent Ezren and Valeros to find it for him. Fortunately, he had arcane marked the pen so Ezren could use his detect magic cantrip to find it. While Ezren was concentrating, it was Valeros's job to protect the wizard, and he noticed movement over behind a stalagmite. I asked what Ezren did, and she said, "I'm going to sneak up and see what's over there." I said, "Okay, you're a wizard, and you're smart enough to know that the big, dumb figher is here to protect you. What you want to do is send him over there and use him as bait so you can cast a spell at the monster." She turned the Ezren mini to the Valeros mini and explained (in a silly accent, no less), "You know, I only have 7 hit points. If I die, it's your fault." They fought a troglodyte and a giant centipede before finding the pen, but she wasn't a fan of playing the wizard, as the fighter got more of the action. She did insist that she keep finding giant centipedes until she had no more magic missiles to cast.
