8 lvl, go swamplings until around 20, then go rotworms until 30, then elf fortress until 60, then orc fortress until 80-90, and then coryms for the rest of his life. I would suggest to not collect loot from swamplings and rotworms, as he'll re-fill to often and you should focus on getting the chars to lvl 80 to safely bot coryms.

For a knight just use a sword, avenger at 75 and gg wp

Sorc/druid, depends on what you want to do with it, on sorc you pretty much hunt solo, druid needs a knight to hunt or it gets boring easily
