I'd like to see a Random Adventure cave (maps, creatures, etc...) whose main purpose would be for leveling up additional characters instead of having to play the original Adventures. Maybe it unlocks when you get a character to level 20. Adventure level and loot rewards would be based on the party you take. That, or allow low level characters into a special MP section which gives XP.
You got your wish. Go to Caverns of Chaos. (You need to complete a level 15 single player adventure to reveal it).
Not quite - CoC gave me the idea though. They are level 21 adventures which are going to be rough for say level 10 characters. MP with low level characters (for experience and loot) would be really cool as well.
No, Caverns of Chaos gives you random characters. The only battle that uses your team us the first one, which I beat with level 11 elf wiz team.
It's pretty simple to level up parties in the original campaign - just always do adventures that are 2 levels above your current party level, that guarantees a levelup after each adventure. That said, I can see the appeal of just getting a random level-appropriate adventure instead of having to play the same old modules.
Yeah, that's what I do. I don't have a big beef with the current system but a random 3 or 4 battle adventure generator (that scales to your party level) still would be nice. I also like the idea of playing lower level MP matches for XP - that would be trickier to implement.
