Khaaven:
It works the why I want at least we can unlock 0 and 1 with the first retire at least.
Next question is at what level will there be henchman at.
I also liked that at the one level we could go to the arena and fight and get free pet henchman.
What do dwarves, halflings, and elves get that we would want to play them.
Not that easy, you still need to unlock something you can start at 1st level (D&D classes only, robbers only start at 1.)
I'm thinking I'm making the standard buildings you'd find in a small town available as soon as you get out. Tavern (henchmen), Market (cheap adventuring items, a few things you need someone working for you like "oil") Doesn't mean you'll have the money to buy anything. For the colosseum, I'm thinking of making that a fighting pit at level 8 with druid unlock.
Elves are fighter/magic users (str & int? or dex & int? not sure.) so they get to wear armor, use swords, and cast wizard spells. I'll have to figure out a way to make that fit with the other PDF classes without being too overpowered. OD&D uses level limits to balance which I'm not fond of, nor do I think it works well.
Dwarves will require str & con and are basically fighters that have bonuses against goblinoids and giants, and can avoid certain traps, and always know how deep they are.
Halflings are str & dex sneaky fighters with some similar bonuses as dwarves.
