One of my concerns about dming OotA is that my players are all low level. Escaping from a Drow prison seems like too high stakes of a way to learn how to play, and having the characters to a tutorial mission sacrices the ease of PC introductions that OotA offers. Luckily, I thy hink I've stumbled onto a great solution.
I'll make the "hard labor" portion of chapter 1 a tutorial. I can create a combat tutorial by making the pcs fight in mini-stadium. I could either have them fight eachother or have them pair off against a monster. This would be an obvious opportunity to have JimJam place a bet, too.
I'm not sure how to introduce mechanics outside of combat. Maybe the Drow could force them into some sort of mini dungeon. Maybe they'll have to do some mining work and the mine could be a dungeon.
The arena fighting wouldn't offer any chance of death on the justication that the Drow don't want to waste their slaves. The mine dungeon could offer some real although small danger. After that I can start taking off the training wheels.
This sounds highly workable. You could have the drow drop the characters into a pen/cage or arena with one or more beasts... just for their entertainment. The drow may let the characters get knocked unconscious, but rescue them before they could actually die. They could start off with one on one matches and work up to group matches. I could see the drow capturing creatures from surrounding areas and bringing them to Velkynvelve for arena matches.
